CHALLENGE: I want someone
to give me a surefire way to hydroponically grow Wheatgrass, easy on
effort and time, no media to use, free of mould even in summer. I have
so many people trying to do it coming into my store everyday, all moldy
rubbish.
I get people with all sorts of health issues from cancer and diabetes, heart disease, all sorts of things like lupus, chronic asthma and so on. I can get a lot of them healthy again, and most problems are fixable. Wheatgrass is a great booster especially those who don't eat enough veggies and I need an easy way to do it. PS if you have anyone with any kind of sickness, give me a try, and I might be able to put you onto a few cures. I live to help people. Scott

Your Experiences 14 Apr 2004 I wish to put a question or two to the people growing hydroponic fodder, firstly are you experiencing any new problems?
I am throwing these questions out there to get people talking again, how many people have given up and shut down their sheds? I am certain that with good communication between interested people we can help each other solve our problems with growing hydro fodder. For instance, at one talk I was giving regarding the benefits of hydroponic fodder, a fellow from Europe suggested freezing the seed for up to two hours before sowing, he believes that this delays the mould growth by enough days to no longer be a problem, has anybody tried this? We have not yet, but will be giving it a go, after all Queensland has its own peculiarities regarding climatic conditions such as high humidity etc and as such we seem to have more hassles than those who grow down south! But I do not believe they are insurmountable. So please, anyone that has an experience to share lets have it. Post it direct to this site so we can all read it. Cheers, Lesley lesleyt1@bigpond.com PS. Some people who have contacted me privately, address the question to Lesley and Scott! Please let me say that I have no affiliation with hydrocentre other than an interest in Hydroponic Fodder and am a grower myself (and my husband Ian!) I really support the forum that Scott has provided for us and have been very happy with any answers Scott has been able to find for me. Aww shucks Lesley (blush).... Thanks for that. I don't charge for any advice. Actually, I don't even remember making any money from fodder growers so I guess its free too! I mostly like to help people find out the answers for themselves, so get in there and try it. Scott |

Mould in Barley
29 Jan 2004 Hi Scott, Lesley here again. Andrew
Olley's reply was quite right, the asp.clav mould spores are present on
the grain. We have found that it is very important to get the pH of the water right, and keep the growing temperature down, after all, barley is a winter crop. I am pleased that we have this forum to exchange ideas, thank you Scott. Another tip:- the quality of the seed is of the utmost importance, I would not by a huge quantity of seed until I had tried a sample, seed quality varies greatly and so does germination percentage, grain is not cheap and storage systems must be considered. If anybody has any experiences with different types of grain, I would be very interested in hearing from them, my e-mail address is lesleyt1@bigpond.com Regards, Lesley |

Hi Scott,
Noticed you had a couple of people reporting cattle deaths and Aspergillus in November. I phoned Dr. Ross McKenzie from DPI to see if he had heard anything about a recent outbreak, but he hadn't heard of any reports. He requested Queensland farmers who find an outbreak to send him an email at ross.mckenzie@dpi.qld.gov.au so he can track the problem. Thanks Dr. LF |

Sorry to hear about your cattle deaths recently. (I saw your letter on Scotts discussion page).
We
have been involved as consultants with hydroponic barley now for a
couple of years and have seen many failures along the way but also
some good success. Our main business is agronomists / technical design
and support to large scale commercial greenhouse hydroponic growers in
all areas of Aust and overseas however we have become involved with
barley systems last couple of years and have been astounded at the
lack of technical knowledge from most system suppliers into hydroponic
crop production and environmental control systems and basic plant
production management management.
In
relation to the mould the key is to sterilize the grain on entry to
your growing system.
The
first mould that attacks the grain is Rhizopus spp which is common
bread mould. This mould is present on all cereal grains to varying
degrees. Many of the production systems utilize very fine climatic
control in an effort to limit the amount of mould spores that can
germinate. We have seen Rhizopus infected sprouted barley fed to
cattle with no side effects. However if the Rhizopus is
allowed to progress rapidly early in the growing system it then
becomes a feed source for more dangerous pathogens such as bacteria
and Aspergillus which will cause problems in cattle.
We
have found that if the grain is surface sterilized on entry to growing
system the climatic conditions can be greatly widened (out to 16
degrees night and 28 degrees day with high humidity) as no mould
spores are on the grain itself and hence only chance of infection then
comes from outside the system.
In
terms of sanitizers for the grain we have found Sodium Hypochlorite
(Liquid Pool Chlorine) to be the most effective used at a high rate
and hence short contact time to surface sterilize the grain. It is
essential that the grain is fully covered with the chlorine and then
washed with clean water after treatment.
Another
important management tool is surface sterilization of all surfaces in
the growing area. Surface spray with chlorine on walls, floor roof and
racks etc should occur every 5-7 days and it is really important that
the growing trays are heavily sterilized between crops.
For
washing walls, trays, floors etc liquid chlorine should be used at 0.1
% concentration ie 100 mls in 100 litres of wash water.
To
treat the grain the rate should be approx twice the above rate to
ensure good kill of pathogens on the grain. The chlorine should be in
contact with the grain for 5-10 mins before rinsing with clean water.
Even your clean water should have a small chlorine amount eg 10
mls per 100 litres to kill any pathogens that are present.
Essential
that all the water used in the system is clear and contains no colour.
If colour is present could be due to Iron or fine colloidal clay in
the water which may use up the chlorine prior to it doing its
sanitizing job. If water is coloured tainted it may need to be
initially chlorinated in a tank then passed through a sand filter to
remove the clay / iron and then re chlorinated to treat the grain.
I
hopes this helps you with your problems.

A.clavatus 29 Nov 2003 Hi. I am involved in hydroponic fodder production in WA and am having difficulty in finding people who know anything about A.clavatus as it affects fodder sheds. The trouble is that all Ag Departments in Australia except for Qld seem to be anti hydro fodder production and will not spend any money to research A.clavatus. We have had a mini breakthrough in WA - a well respected nutritionist and an Ag Dept./university research officer are about to do some serious feed trials here on cattle and sheep, and the senior officer in the Ag dept is keen to carry out real life testing of A.clavatus at the same time. I have just manufactured a mobile fodder shed - based upon Peter Ryan's fodder factory principles - and it will be used for the trials from February. Further to that, I am conducting my own trials on tray types, different nutrient types, different grain types and have come across a water conditioner (German technology) that has controlled an array of algae and moulds in differing situations. I have installed one in my mobile shed and expect it to assist me with general hygiene on the trays, walls and ceiling. If it can assist in the control of A.clavatus then I have a bonus. My second hand experience over here with A.clavatus is that three different people have lost cattle with feeding barley - all in high humidity situations where the temperature climbs. One fodder factory that has been operating for four years without problems has always kept the temperature below 24 but there have still been A.clavatus present - but seemingly dormant at low temperatures. If I have any success with any of this in the next three months I will be making the findings quite public - not because the findings will be conclusive, but because it would be some comfort to people like you and me who are currently starved of any information. Cheers BG |

Mould and lighting problems 22 November 2003 Hi Scott, I am not in a panic (well I tell myself this!) but we have found aspergillus clavatus in our sprouting barley grain. We have dumped all infected product and want to know what we can spray to ensure that there are no spores left in the coolroom or on shelving and trays. Also our current lighting is very dull, what type of wattage do we need to replicate daylight? Our coolroom may have been a bit warm, hence the mould, I am thinking 18-20 deg. Celsius, what do you think. Thanks in anticipation, Lesley Thomson Qld. 1. Cleaning with Pool Chlorine is most commonly used and most cost effective. Check with Dept of Ag for any better tips. Its pretty difficult to remove I have been led to believe. 2. Lighting is usually good fluros like ACTIVA 98% Colour rendition (4ft tube $19.50), kept very close to the plants, or Metal Halides 400Watters every 1mx1m, 1000Watters every 2mx2m. Electricity and water generally mix badly, so think about protection for the lamps. Some sort of shield or waterproof fitting would be advisable. Or skylights - but then heat is an issue. Scott |

CATTLE DEATHS - lanes1111@hotmail.com 19 Nov 2003 Dear Scott We have a small farm with a fodder shed in southern Victoria. We have had severe mould problems with about 20 out of 100 die on us and a lot more seriously ill. We had the fodder tester for toxicity but at the time it free from A. Clavatus. A couple of weeks later it developed and we have found ourselves in trouble. We understand that there is nothing we can do for our cattle but wait it out and hope for the best. It sure was a huge morale boost to finally find your site and discover that we are not alone with this problem. We would really like to get in touch with others that have been through this or have found solutions to this problem but we don't know where to start. Can you put us in touch with those who have experienced this situation. Thank you so much. Lainie I am sorry to hear about your situation. I'll pop this up onto the site and ask them to contact you, And I would ask if a copy (cc:) could be sent to me at scott@hydrocentre.com.au to ensure that information is updated on the website for everyone. Hopefully they will all come out of the woodwork and we'll find out how widespread it all is. Scott Dear Scott Thanks for being so prompt in your reply, we really appreciate your assistance. We are very nervous about taking it up again given the fatalities we have had to date, even if there is a way around the toxic mould problem. We would be interested in talking with anyone who grows Hydroponic fodder anywhere in Australia as we are so new to the process. Thanks again Lainie Dear Scott I was wondering if you had heard yet from anybody that may be in or have been in the same predicament as us. We have had no more fatalities over the weekend, we seem to be over the worst of it now. The problem is we have invested in this wonderful shed and we are wondering how to modify it to incorporate a facility that allows to efficiently wash our grain, and/or what are some other options for our shed. Perhaps we should branch out and try germinating other grains? Perhaps we should try growing food instead of feed? If you can help us to get in touch with others who have invested in the simple shed, fodder factory or the like it would be a great benefit to us. These companies, for whatever reasons, are not prepared to give out the names of their other clients so it is up to us to do our own investigations. I wondering about George. I have been reading his letters to you, he seems like he is running a successful system. He also seems to be very open and willing to share his ideas and experiences. Is it possible for us to contact him directly? One other question, will you be publishing the original letter that I wrote you? Thank you very much for your support. Lainie. I'll send George an email. I have had a large company with vast resources unable to beat mould, and others who have no troubles. Seems difficult to pick a solution. I will certainly let anyone know the solution to the problem. Hi Scott Thank you for your information much appreciated, I have sent this to Lainie, one thing I forgot to mention was that the quicker you can get the feed out of the shed the better, Regards G Hi, I got a message from Scott to E-mail You, Hope I can help. We ran our shed for about 9 months flat out, and we sure had some problems with mould, I think the mould comes mainly from the grain itself, the trouble is that barley is by far the most suitable grain for the shed, and it is the grain most likely to have mould. The first lot of grain we used had been stored on farm for about 7 months and we didn't have many problems with it, the second lot of grain came straight off the header, and boy did we have problems then, that's why I would look at the grain first, You can try to first clean the grain up by grading, washing, and soaking it in "Pythoff" (Scott can supply this) . If I start the shed again I would put the grain in a cement mixer an run water through it until the water came clear, with this method you could float off any rubbish and husk off, then soak the grain in Pythoff for 2 hours, then drain it off , there is no problem spreading the wet grain in the trays. The next thing you have to look at is the cleanliness of the shed and most of all the trays. We were very particular about this. After we have emptied the trays they were soaked in a tub holding 300 lt. of water and in that I would put 1 lt. of pool chlorine, and soak for at least 15 min, then we would scrub them clean, sounds a bit of work but in the long run worth it, we would then wash the racks down and then spray them with a strong chlorine solution. When mixing up the nutrient solution we would put 1 lt. chlorine to 22000 lt.solution. ( the tub I mentioned can be purchased from Rapidplas Tanks they call it a creep box). I hope these rambling's will help you, the ones that sell us the sheds don't know all the answers, none of us do, we are all on a steep learning curve, it is very easy to make mistakes, some very costly, with Scott,s web page we can all share our experiences and together we might solve some of the problems.

Fodder Question We are on our way. 14 Nov
2003
Hi Scott, my husband and I have set up a growing system at home, not a turnkey system, but a large climate controlled coolroom capable of growing between 4 and 6 tonne per day of barley sprouts. We want to sell the fodder to farmers who need or want to try this food but have neither the capital or the time to purchase a factory for themselves. We have been setting up our growing room for a long time now as research and money have both been needed, thank you and the others on this page for your input as we have gleaned a lot of valuable information. If anyone wants to contact us personally they can e-mail us on lesleyt1@bigpond.com Thanks again, Lesley Good Luck I'll publish this for the farmer to see. Scott |

Peroxide levels for mould 29 Oct 2003 Scott, I have the same question as most, re mould , have read all question and answers and would like to know how much peroxide can be added to a 25,000litre tank , also how much would you mix to wash the seed in, everyone tells you what you use but not how much. Thanks Glenda Well, the simple answer is to get a test kit and add until the desired ppm is reached. How much is desired? A residual of a small level is good. Growth Technology make a test strip and I am getting them in stock soon. 50% Peroxide can be added at around 20ml/100litres every 2-3 days, or 10ml/100litres daily I have a saying that no-one gets a simple answer from me. The long answer is that Peroxide products release oxygen and water as a chemical reaction when they come in contact with the nasties in the liquid to be sterilized. In the process the H2O2 becomes H2O and O2, leaving no peroxide. If you have 1000 units of nasties, you will use 1000 units of peroxide to kill them. If you add 1000 units of peroxide and there is only 500 units of nasties then there will residual peroxide, and if there are 2000 units, then you have no peroxide and a residual of nasties. Using an approximate level means everyone has the same level of nasties, and that is just silly. You have to dose enough to get the problem fixed, and not waste the product by using so much that you end up bleaching the roots So if you have test strips and there is a residual, then you have protection against nasties floating in you tank and you add small amounts to keep it there. (under 10ppm would be fine for me) Peroxide won't last for long in a moving tank of water, so don't panic if it disappears, you are looking that after adding a small amount it gives a residual reading on the test strip. If you use a lot to get a test strip reading, then there are still lots of nasties so dose regularly. The speed of peroxide reaction is what gives you an idea of what levels are in the tank. To make the peroxide last longer out 6% peroxide has a silver ion added which elongates the effectiveness in the solution and protects the plants for longer. This product is for home use and is called Hydroshield. (Nasties: my highly technical term meaning bad things such as single celled organisms like fungus, mould, bacteria, and nots so bad things like algae) Scott

Fodder Question Can Hay be made from
Hydroponic fodder. 29 Oct 2003
I have a few questions .Has anyone tried making hay from the fodder produced? If so what if any special procedures are required. The other is to do with trays. Way back you said the cost for trays would be $5. But from where did you source them? I intend to use a insulated shipping container (have seen it produce successfully )which will produce about 200kg/day does anyone have a successful more cost effective housing solution? Keep up the good work very interesting. Hay from Fodder? You wouldn't harvest the fodder roots and all, so that would be different. If you are doing it for storage thats good. Fresh fodder should be more nutritious though. The Shipping container should be good, keep an eye on that temperature, stale air pockets etc. I think a lot of constructions can work. Ventilation is a key to avoid mould. Air conditioners are a good idea. Scott |

Good open information 04 Sep 2003 Dear Scott, Well worth a read for those that want to do it in a small way with good results and at a reasonable price. Peter Thanks for the information. Shows how simple you can make it work. That link seems to be quite useful. Hope everyone has a look. Scott |
| Dear Scott, Keep up the good work, your page helps growers by getting the right information from actual growers, much better than from the manufacturers of sheds . your page was a great help to me. G |

education 20 Aug 2003 scott i think you should learn a bit more about fodder before giving people advice about it I have left the name off this email as I always do, but it was from an fodder system manufacturer/advisor. At first I was a bit hurt in that I do like helping people, but I won't ever hide from criticism. I thought about it, and guess that it might be a good idea to ask if anyone thinks I should lay off giving my free advice please email me at scott@hydrocentre.com.au - and I will quit if I think it is necessary. All farmers should do their due diligence and check out that something told to them actually works before justifying expenditure. I always believed there are easy ways to grow fodder, and to get trouble free fodder this may not be entirely possible without setting up a more expensive system. As all crops can fail so can fodder. Most of the turnkey operations eliminate most of the hard part of growing, but leave growers without a true understanding of why the system works. I guess its a consumer decision to either choose a system that gives you instant results and a 24 hour phone assistance, or work it out for yourself. I speak here of my experience with vegetable farms as well as fodder. My experience is almost entirely in the Hydroponic Vegetable and Herb industry and have helped a lot of people setup in fodder, from my hydroponic experience (read as not specifically fodder experience) of 13 years. I haven't had any complaints until today about my fodder advice, so I will continue to be honest about the whole thing, and hope I never stop helping. I guess I am a little down about making any effort to help today. Scott |

Found source of "Warning for Cattle
Owners' story 08 Aug 2003 Hello Scott: I have tracked down the source of the fodder-mould-cattle-death story, both originating from the same source: Now we know. Source: Queensland Gov't - Dept. of Primary Industries 26 March 2003 Caution advised with mouldy hydroponic fodder The Department of Primary Industries is urging cattle farmers who are using sprouted grains to feed their cattle to be extra vigilant in ensuring the grain is not contaminated by a harmful species of mould. According to DPI Animal and Plant Health Service (APHS) principal pathologist Ross McKenzie, four separate incidents of cattle poisoning have occurred in the past six months due to cattle being fed sprouted grains that were infested with a heavy growth of a particular kind of fungus. The mould, identified as Aspergillus clavatus, is identical to that found in similar poisoning cases in South Africa, Israel, France, England and China and is found in soil and cereal grains worldwide. "While the fungus is well-known throughout the world, the actual occurrence of poisoning by it has always been considered quite rare," Dr McKenzie said. Producers should keep a watchful eye out for the fungus, which can be identified in sprouted grain due to its blue-green colouring and mouldy appearance. Confirming its identity requires microscopic examination by an expert. "It is thought that the heavy growths of the fungus which poisoned the cattle may have resulted from elevated temperatures in the production facilities, especially during the summer months. In some of the poisoning cases, owners reported that breakdowns in the temperature control systems for sprout production had occurred before the cattle became ill. "Even a few days exposure to temperatures around or above 24 degrees Celsius is enough to cause a flush of fungal growth on the sprouting grain," he said. Poisoning damages the spinal cord and brain tissue, and signs of the poisoning, which may take up to two weeks to appear, include cattle walking stiffly with poorly coordinated hind limbs. Less frequent signs include drooling saliva, loss of appetite, difficulty with breathing after exercise and convulsions. According to Dr McKenzie, mildly affected cattle probably have a reasonable chance of recovery from the illness. Of the twenty-five cattle known to have been affected by the fungus, the eight most severly affected died or were killed humanely. Producers who believe they may have identified the fungus in any type of sprouted grain and are seeking confirmation should contact the DPI's Veterinary or Plant Pathology Laboratories through the DPI Call Centre on 13 25 23. -------------------------------------------------------------------------------- Further information: Dr Ross McKenzie.

The Department of Primary Industries says four cases of cattle poisoning have occured around Queensland recently - stock were fed hydroponically grown grains, infested with a fungus known as Aspergillus Clavatus. DPI Principal Pathologist Ros McKenzie says while hydroponically grown fodder seems to be the "in thing" and normally the sprouted grass is nutritious and cost effective, users must take care. There is no treatment for stock affected by the mould, which appears to caused by overheating the sprouting grain. Therefore, Ross McKenzie says producers should be on the look out for the blue-green mould on feed.

will a tunnel suit to grow fodder 07 Aug 2003 Scott I live in a hot climate but have an old tunnel on my property. It is a cool place seldom above 20 c. and has a very dry climate inside. Would this be suitable to turn into a fodder shed? And if so how much and what type of light would be required? I have looked at both the Fodder Factory and the Automatic Paddock (fully automatic self seeding and harvesting unit) and I can't help but wonder if I can do it myself. Thanks for your time regards Al Lots of growers have done it themselves. I still say you should try and get some seed and some trays and water them to learn more before getting into it. Most of the questions on the site www.hydrocentre.com.au are from people who don't have the cash to setup expensive turnkey operations. Saying that, it sounds like light levels don't appear to be high to get good growth, and fodder grown in shade seems to grow well enough. Its an issue of mould. different depths of seed, humidity, cleanliness, temperature all seem to play a part. I recommend some experimentation in your shed and see if mould is a factor. My guess is you might need to look at temperature if it is much below 18 degrees. Sprouting might become a problem - but give it a try. Every shed is different. Scott |

WARNING FOR CATTLE OWNERS 06 Aug 2003 I have a fodder factory in operation which works very well. But I recently got some green mould on the seed from the 5th - 6th day onward. After sending it to the lab to get it tested it was identified as aspergillus clavatas-a very nasty mould toxic to animals and humans. After doing some research into this mould I found out that it was first discovered in the 1950 in the process of making beer. From 1950 to the present it has killed hundreds of cattle all over the world notable 200 dairy cows in Bulgaria in one hit and they were feeding them sprouted malting barley ex-the brewery. Some tests were carried out as brewery workers were getting very sick and they found it was this mould which spores in the air as well, and in the old speak is called brewers disease! This paper I have on the subject notes of test carried out on malting barley and found that 32 percent of sprouted malting barley will contain aspergillus. This I found quite astonishing as all along I thought the mould problem was due to hygiene or humidity. But it is not it is a scientific fact that it grows on the outside of the seed itself. I am writing this as all the deaths of cattle in Australia from sprouted barley had evidence of this mould and it is essential that people know not to feed out the fodder if any sign of this blue/green furry type mould on the seed. Tests found that in cattle, it affects the hindquarter first as if the animal is lame in both legs. Hope this info is useful to others as it has affected our operation and seems to be solved with a mix of hydrogen peroxide and chlorine in the nutrient tank, and also rinsing the grain. Thank You for this information. Since I have no knowledge of any deaths of cattle and never seen a green mould, I am unsure what to say. The moulds I have seen are not green, although algae is green, and different to the green mould described by this email. No mould is definitely the best growing situation. I will let you decide about the above information, and if you have heard more about We know that Hydrogen peroxide is a good sterilizing agent, which is neutralized by Chlorine (so don't use them at the same time), and Chlorine should kill moulds as well. I have been recommended R and D Aquaponics anti-mould product for fodder, and will get some in stock soon. Please forward this sort of information for the benefit of farmers. One post below mentions deaths, but I have no knowledge about that report either. If you have any further information please advise me at scott@hydrocentre.com.au and until then, don't panic. I reiterate that I have no knowledge of deaths, and perhaps I have not been in touch with these growers yet. Scott |

Nutritional information 4 July 2003 I'm having a hard time finding complete info on feed analysis for greenfeeds sprouted from different grains and beans. I've checked many sights on the web with no luck. I do too! http://www.rdaquaponics.com.au/12403.html is not a bad site from a Sydney company http://www.hydroponics.com.au/back_issues/issue35.html a story on the fodder factory from Practical Hydroponics http://www.sproutnet.com/nutrition_research.htm may have some value in some of the articles on Barley etc. http://hwy.com.au/~rcharles may have some useful information http://www.fodderfactory.com.au has some info, but you'll need to ask for specifics. I found these links by searching www.google.com.au with hydroponic fodder nutritional analysis - here is the link. I only searched the first 3 pages. http://www.google.com.au/search?hl=en&ie=UTF-8&oe=UTF-8&q=hydroponic+fodder+nutritional+analysis&btnG=Google+Search&meta= You can try more types of searches yourself. PLEASE let me know of any good information on this so I can update my site Thanks Scott |

Automatic
fodder machines, are they available??? Hi
Scott, Have
just found this forum and would like to ask you a few questions, no
doubt I will have others but for now: I am
interested in the availability of auto seeding and harvesting fodder
machines as it seems the labour cost / time needed to run the manual
models, to some extent at least, undermines the economics of installing
them in the first place. I
have heard on the grapevine there is one about to be released in WA but
I can't seem to find out much about it i.e. costs, size etc, there may
be others available but it would seem automation is the stumbling block
to market acceptance of fodders feeding and its undeniable benefits
particularly in summer and during periods of drought. Also
have you any details on the various airborne diseases that affect
fodder, I heard recently a report on the ABC where someone lost their
entire heard (cattle) that was being fed barley fodder but unfortunately
I was driving at the time and missed its name but it sounded very
serious, have you any ideas as to what the preconditions are to these
diseases occurring or where I could find out, cleanliness I understand
plays a large part. This
is a great page buy the way. From
W.A. Good
Questions 1/
Auto seeding - good idea. I'd never use it, because to get the seeds
level on a tray, and automated would be cost inefficient by the time you
have mastered the mechanics. Auto seeding works for other propagation
systems, however I am skeptical of any benefit from automation.
(Automation is my current problem. Too many motors, not enough brains)
For instance, some guy marketing to richer Asian markets has build a
motor driven system that hauls the fodder up to the sun, and down again.
The cost is astronomical, and if the land weren’t so valuable there,
they'd never sell one. Now poor farmers come along desperate to get some
feed to save the farm, put the 200th mortgage on their house just to pay
for the damn thing! What a waste when they could have produced 4 times
the amount with a simpler system using a bit more space. Gadgets
are good but not always necessary. My 6-month-old laptop here has a
DVD player in it. Like when would I use it???? Business is business. Why
not work out costs on a simple system, vs. a complicated system. I could
be wrong, but also if there's a job in it for someone, and it costs
less, give it a go! If I am wrong then I think that’s good too. At
least we thought about it first. 2/
The cost savings on the whole come from NOT having a complicated
automated setup. Automating some things would work better than
automating the growing - such as automatically washing the seed before
start, automating the tray washing would be a great help, nutrient
mixing (using one of our nutrient dosers) and temperature control with
fans and air conditioners. Having the trays in racks that are on wheels
could help. Wheel them out for harvest etc. Just disconnect the
irrigation first... 3/
I have never heard of anyone losing animals to fodder that animal would
be expected to eat - e.g. we already know that Alpacas get dizzy on some
rye grasses so we don't do those grasses.... Mould is a problem with
some animal’s digestion, but animals generally don't touch anything
mouldy if they don't like it. I hear that cattle can eat some mouldy
stuff because of their four stomachs even. It is possible that an animal
could get sick on any pasture, grown in a tray or in a field. It is
probably an external thing, such as problem in the water supply or some
such thing. Its fairly unlikely considering growing lettuce and tomatoes
etc is a very similar process hydroponically and we humans never get
sick except for the allergies/pesticide residue/contaminations which
make me grow my own at home anyway. Thanks for the question. I will remain a K.I.S.S. advocate, but let me know if you can make that fodder system dance! Scott |

climate
control Scott
reading other questions it seems that temperature is all-important -
especially in controlling mould. I've seen models such as the fodder
factory with gas heaters and evaporative air conditioners. Would a
simple heating/cooling unit that you can set the temperature on say 23
degrees and keep the room constant at that temperature work, such as is
available for houses. I am looking at purchasing a shed but have a few
more different models to check out first. I'm more interested in
fattening lambs rather than cattle. Can you please put me in touch with
anyone who might be feeding lambs hydroponic barley as I’m starved for
information? Hello Yes
we are all starved for information unfortunately. 1/
Mould is related to humidity. Once the mould is in, the temperature
relates to its growth, and unfortunately the fodder likes the
same temperatures. 2/
Air conditioners seem to be the best way to dry the air, reducing
humidity, and to keep a suitable growth temperature. 3/
Hydroponic Barley is the same or better than normal fresh barley grass.
Ask your vet for an opinion on the barley and other grasses effect on
fattening lambs. Let
me know what you decide and/or find in information. We are all learning
here. Scott |
| Not a question - just
thanks!!! 30 May 2003 Scott, Just a quick thank you for operating this page. I have been trying to make sense of the whole fodder question and keep finding too many brick walls built by people who have vested interests. Thanks to all of those who contribute with such great input. One day I will be in a position to help someone else out as you have me. All the best Peter As I sit and answer all the same question over and over for all those people who ask the same questions over and over, I find someone who actually reads the pages. Thanks back at you - nice to be appreciated. Scott :P |
| Fodder Factory 7 May 2003 Dear Scott, Thank you for your previous emails. I appreciate the information given to me. I have recently heard about the Fodder Factory and was wondering what, if any, experience you had with it, and what information you might have about it. I am extremely interested in finding alternatives for farmers to help them through the drought. Thank you again for your time. Fodder Factory is a fairly good system. I believe he has built many units, and no complaints except if the air-conditioning fails it becomes a mould factory. Should be a good investment, fairly liberal in the cost of assembly - but you should get good support from experienced grower which is worth extra money. Farmers could build it themselves cheaply, but experience, a pre-built system, and away you go is very good also. I would caution farmers that you usually spend more time operating one than advertised, especially when inexperienced and some failure might occur in mould if everything is not clean. Scott

| Can you feed barley fodder
to horses? 5 May 2003 Dear Scott Can you feed barley fodder to horses? If so how much can they have? Is it safe? Any info on this matter would be appreciated. I have farmers doing it, but check with a vet for safety. I have had a few animals like Alpacas that can't take certain fodder, and we work thru their vet to discover how to ensure a good quality feed. My quick look on the net at www.google.com.au gave me these sites mentioning a benefit of Barley especially as a grain, and as a grass. http://www.holistichorsekeeping.com/husbandry/wholefoods-nutr.html http://horses.about.com/care/nutrition/nutrition011903 http://www.care-for-my-horse.com/html/nutrition.html http://petshub.com/horses/nutrition/horse_nutrition.php 5000 pages more at http://www.google.com.au/search?q=horses+nutrition+barley&ie=UTF-8&oe=UTF-8&hl=en&btnG=Google+Search&meta= Hope that is all helpful and let me know how you go...

| Barley fodder unpalatable 20 May 2003 I grew some hydroponic barley fodder last October with amazing results but the cattle wouldn't look at it. Took a bit of a nibble and headed back to the barley straw! In a previous response to a question you said barley can smell pretty bad and you suggested rinsing it. Was this for the seed going in to the trays at the start or for the fodder coming out at the end of the process? Good Question. Farmers tell me that the nutrient mineral salts on the roots are not tempting, but once the minerals are rinsed off the response is normal. So instead of watering fodder last 12-24 hours use plain water or rinse with fresh water once harvested. How much will be easy to work out. If they don't eat it, rinse it again. Scott |
| Work for the Dole for
Farmers 16 April 2003 Dear Scott, I am currently undertaking a Work for the Dole project in which we are researching drought relief ideas for farmers and producing an information CD for them. Part of our aim is to offer new strategies and ideas to help overcome effects of the drought and to prepare for future droughts. I was very inspired by your web site and would like your opinion on the relevance of hydroponics for farmers on both large and small properties. I am also seeking information as to ideal set up situations, costs and effectiveness in producing different crops relevant for cattle. I am looking forward to hearing from you. Thank You for your time . Yours Sincerely Hello, Water needs to be pure, not tainted with salinity. Overcome that, and you need to have a business plan. There are lots of crops you can grow, but need a market to sell the produce. Best crop at the moment is hydroponic fodder. Fodder is useful, especially for breeding stock, valuable animals such as alpaca, racehorses. Takes about 5-7 days to produce fodder. All the information at that site is relevant. I will put up this question and let the farmers answer it from feedback. The best way to find out is get some barley seed (big sack is under $20) ,put in tray, water with water until moist, when dry do it again. Scott |
| Fodder update. 16 April 2003 Hi again Scott Just as I think the mould is under control, up it crops again, maybe its the wet weather we have had lately. At 63mm , great, I have cut the watering time back to a minute every 4 hours, with only one water between 8pm and 8am , we are pulling the fodder out as soon as we see mould. sometimes I think these sheds should be called "Fungus Factorys" Any money in fungus?? But it has kept my Cattle going. Regards George. Georges sheds are in photos below - Scott |

| What is the best humidity
level for fodder production Saturday, 12 April 2003 Scott, we have started a small fodder shed, and had been told or read a humidity level of around 70% is optimum. Is this correct as the commercial sheds are using air-conditioning to control temperature? OR do they re-humidify after cooling? We also have encountered mould! Do you know if a Slow Sand Filter will treat the water sufficiently or will additional treatment be required. Currently running at a pH of 6.4 and EC 1.4, would like to know what other people's values are like. Would like more info on you nutrient mix. regards Kevin Scott Responds Kevin, you sound like you have it all up and running. The main reason for the Air conditioners is to keep it under 25 degrees and dry air to get rid of the mould. Dry is good. 70% is probably too high. Mould comes off the seed, and can come from the water. Water can be sterilized with UV, Ozone, Hydrogen Peroxide, and most popular is Pythoff (Monochloramine) Standing tanks can be sterilized with Chlorine/Bleach. The chlorine/bleach must be eliminated before contact with plants by aeration or Hydrogen peroxide. pH of 6-7 is safe in all Hydroponics. EC 1.4 (This is a CF14 or 700-980ppm depending on your meter) I would think about 0.8 to 1.6 is fine. Look at your growth compared to humidity and temperature. High EC slows growth, but increases weight. You may find high EC linked to heavy growth and slow growth which could be linked to mould in dense growth. The EC is linked to the transpiration rate (Its sweating of moisture to allow further uptake of liquid) which is reliant on the environment. Raise the temperature for example; there is a higher transpiration (think sweating) and you have to the lower the EC to get a similar result. Increase the airflow over the fodder and the transpiration goes up. See our pages on CF control here particularly advanced control on pages 3 and 4. Because of the environment, every green fodder grower will get slightly different results even if using the same EC/CF. Nutrient mixes are pre-packed General Purpose Commercial Nutrients. I have had much concern over the trace elements for fodder if using low EC, but high EC works fine. A fodder mix is on my list, but I am not keeping up with the demand for my services at the moment so fodder nutrients is on the back burner at the moment. Want to do it soon. Want a Holiday badly also. Oh well. Can't have everything. Prices: Our current mix is a 5kg $50 pack making around 50,000 litres. (use
nutrient from day 3 onward) Delivery is negotiable. Scott |
| Fodder Update on Mould
Hi Scott, I would like to comment on mould in fodder sheds. We have been using Pythoff , and it is keeping the mould under control, we soak the grain for at least an hour, let it drain for about 2 hours, then put it in the trays. We also treat supply tank, and flush racks when empty. Still get a bit of mould at 7-8 days, but this doesn't effect growth. regards George Thanks for the update George! Could you pull the crop before the 7th day so the mould hasn't set in (Cattle not much affected - all those stomachs - but knocks other animals about) Is it big enough? Sounds like a solution but isn't it a lot of work? Scott :) |

| Smaller fodder operation Tuesday, 18 March 2003 We are very interested in growing green feed Hydroponically which would be suitable to feed out to cattle, i.e. barley/oats/wheat etc. We need to be able to germinate the seed and grow to about 12" high in a period of about 7 days. We need trays that would be easily handled . As we are hobby farmers and at the moment only have 20 head of cattle, we do not require the expense and outlay required by the Fodder Factory. We would like some help and suggestions for building this ourselves. Any literature you may have which would help us get started would be appreciated. Trays - still a
problem. Seeing the pictures on the fodder page in questions there is a very neat greenhouse, with a light shield (silver reflective) over the top of the trays, and the light comes in thorough the sides mostly. The grower has used a large air conditioners to keep it all cool/which is an optional thing. All the rest of our information is being posted to the fodder site continually. The real problem is
companies that have information want you to pay for it. As always check the
site regularly, ask questions, but try and do some experimenting for
yourself with some shade cloth, plastic tray and some hydroponic
nutrient Scott Andrew |
| Subject: greenhouse mould
> We are only just starting into fodder production of barley (3 tonnes per day) and have encountered mould problems. Some of the equipment has pumped with questionable efficiency. We are starting over with pretreating seed. What dosage of calcium hyperchloride would you recommend to address the problem, both through tray washer and overhead sprinklers? Is this the most effective/efficient product to use, as we are feeding 7-8 day old shoots to dairy and beef cattle? Not happy with calcium hyper chloride - might as well use pool chlorine. Fodder will not be happy. Has anyone else used calcium hyper chloride? Ensure there is good drainage in the tray - no water left, all draining. wash seed before putting in trays Never let your hands touch the seed - use plastic gloves. Do not disturb seed once rootlet emerges. discard water from first 2 days. Use nutrient from then on. Best product seems to be Pythoff - Monochloramine. Treat all water sprayed onto the fodder. Treat water storage tanks with a shock dose as well. Ensure good ventilation (this would show as mould in some places, not in others. Keep the heat down to as close to 22 degrees as possible.... Please don't laugh - I'm serious..... Oh well do what you can. the higher the temperature, the worse the mould. Use pool chlorine to wash the trays between crops. Keep an eye on the fodder pages and questions, for updates on fodder production. Good luck. Scott

| I thought I would share
these photos supplied to me by George.
Thanks to his generosity, you can all
see how a working unit is set up.
The shed took about 6 weeks to build. building the frame and racks took up most of the time. mould is no 1 problem, humid days don't help, but up to now we haven't had a lot of them. The shed has been operating for nearly 5 months, 25 tonnes of barley seed kept it going for over 4 months with a weekly output of about 7 tonnes green matter and root mass, stock eat the lot. The fodder companies of some of these sheds put the labour down at 2 hours a day, which is a load of bull*** . You have to spend a lot more time than that, to get good results, but it pays off in the long run. Hope this gives you a bit more information. Regards George.

| Mould in fodder factory Thursday, 27 February 2003 I live outside Kingaroy in Queensland and have recently installed a fodder factory. I have encountered problems with mould. The addition of sulphur to the nutrient tank has seemed to deal with black mould but lately we have gotten a severe problem with a white mould. This is worse in humid weather associated with the rain we have been having lately. The cows seem to eat it without harm but it stops growth and badly affects production. I am wondering if there is anything I can add to the nutrient tank, like peroxide, that will help with this problem, and if so what quantities are safe to use. My nutrient tank is 27,000 litres. I have noted the advice on presoaking the seed in a 1% peroxide solution but am reluctant to do this because of the difficulty in spreading wet seed in the trays. Do you have any suggestions on this? Humidity has a lot to do with the problem. Try to air condition the area or use fans to keep humidity down. If mould is in the air from spores, maybe have your fan intakes come in from a higher point like through the roof, not near the ground where mould often lives. The seed is often the source of the mould. I highly recommend washing some seed thoroughly and see if trays washed produce low or no mould. Try also some sterilizing of the seed as well, use hydrogen peroxide or Monochloramine, and compare that too. I think it is worth the effort, once you get used to it. Sometimes the source is our hands. Don't touch the seed. EVER. Use gloves. Do not disturb the seed once it has been placed into the trays. Sometimes the source is the water supply. Sterilize the water and test that theory on a few trays. I seem to think that Fodder growing is not as low a labour activity as the sales people try to make it sound. It is not excessive but washing and cleaning is very important. I also think that air conditioners make it much easier, as long as they are not blowing up. Make it a good model with too much power. Good Luck - Scott |

Fodder Production Wednesday, 12 February 2003 Dear Scott, Scott responds: Thanks for your question. There are a great number of websites that
describe businesses that produce pre-made fodder machines. We are working more to help farmers build
their own than provide pre-built solutions. Costs? No idea. Ready made units? Quantities produced? Crop selection? On the subject of pre-made machine
suppliers...... Please keep in touch, as I would like to
make up some sort of page just for Fodder Until then keep emailling me and I will
keep you up to date. Scott Piggery shed into hydroponic fodder for cattleSaturday, 18 January 2003 Scott, We have an old disused piggery shed, built with cement bricks, with some added natural light intake can we grow barley grass in this type of building, single layered? Scott's response: Umm, possibly. The issues would be
Hope that answers some and doesn't create too many new questions Thursday 2nd January 2003 I have a fodder shed 15m.x 6m. Would your large ozone generator cover this area. Scott Responds Ozone is a great way to treat mould. My latest information seems to indicate washing the seed well with a sterilizing agent like Hydrogen peroxide, or Monochloramine etc. will eliminate the fungus/mould problem at the source. As for Ozone and how effective it would be, the Variables would be how well the ozone could mix throughout the room, the leakage rates, it might be too much or too little. Sorry, can't nail me down on this one. I will say we give a money back guarantee with all ozone generators. Mainly because I am such a nice guy (cough) and also because of the setup problem. I need to help you set the generator up to spread throughout the shed. We want to have the ozone effective in all areas, not strong in one area (eventually produces burning), and weak in the other areas (ineffective). Mixing all the air with some ozone may require some fans, and some airflow corrections using either fans or ducting. Perhaps closing the shed for 30 minutes per day and allowing the Ozone to build up will work. We want the ozone levels to be fairly even, so some sort of distribution of air is still needed. Constant ozone and air flow with the shed open will work too, as long as you ozone the fresh air entering, and it spreads. In some sheds, it will never work without modifications, some sheds will work fine. Without knowing if you can try these things, I would have to say "Maybe" because it might not work, the ozone unit is powerful enough, but the shed could be a problem depending on its design. How much is a unit to produce up to 1000kg of fodder a day? Or how can we find a site / shop / person / advice on designing / buying a unit that will do this? We have water, but no feed. Will it work on bore water? We can find site, with prices from 2000, which we assume is out of date!! Is it possible to get too hot?? (45 degrees is common!) Any help gratefully received! Scott responds Very good Questions! I can tell you what we know. Barley seems easiest to grow in the heat. Lay the seed in trays (kitty litter trays or similar sizes), spray or flood and drain them with a nutrient which has a low nutrient strength but modified trace element mix. In 24 hours they sprout a root, green shoots day 2 and 3, by 5 days you can early harvest, 7 days is about max before they slow down and behave more like slow growing grasses. High levels of light are not necessary, but cool temperatures are. I recommend shade. Since they like to be below 25 degrees and you are that hot, you should forget the shade and put a solid roof over them, insulated if possible, and shade cloth sides to the building. Barley must be well rinsed as the smell from un-rinsed barley is pretty bad, the chemicals sprayed before harvest need to be removed, and root rots will happen if you don't. My tests on pre-soaking seeds to make them sprout have not shown any difference in speed or results. The yields relate to how much seed you put in a tray. Deep layers of seeds give weight for a given area because there are so many shoots close together. There is more chance of rots and moulds because it is so dense, and I have encountered that at 28 degrees fairly often. Less seeds reduces mould and yield. Also keeping sterilizing agents in the water helps also. Hydrogen peroxide, Ozone units sterilizing the water, and Monochloramine all work to combat any mould, fungi, bacteria etc. I don't believe you need a lot of money to build a system, but to make a system 100% reliable, same yield all the time, no wastage from rots, you would need to spends tens of thousands. Bore water may be too saline. Have it checked for suitability first with a water test. Try the Fodder companies and check with their
customers. They should give you some customers who will vouch for them.
Some companies like www.fodderfactory.com.au
provide a whole service, and provide complete products that will work
well and give you the results you require. I want to do more research
into producing something more cost effective. As I produce more info I
will try and update this site, and this question of viable fodder
production
Scott Response to Fodder Growing 16/12/02 I have a fodder shed You mentioned monochloramine, could this be used in the supply tank (5000gal) And its cost. This shed produces over a 1000kg a day, works on bore water, the only trouble I have is calcium build up and it is blocking nozels, plus I am getting fungus on 7th & 8th days Scott again - Yes, but try sterlising the
seed with the Monochlormine first. This may give you a more economical
way to eliminate the mould/fungus/problem. The tank would require a fair
amount to treat, so I would try washing first as the seed is often the
source of the problem. (seed sitting in a warm silo, lots of nasties
could grow there depending on treatment) Further responses: Thanks Scott for your reply, My shed has settled down, I think most of My problem came from the air conditioner, it was getting blocked with dust thus making the shed very moist, I am cleaning the pipes with C.L.R. and using a magnetic filter on the supply line from the bore, seems to be working ok. Great! - Scott |
