Growool Premium Floc 13.6kg is loose Rockwool mostly used for filling pots and containers for growing.
Also known as granulated Rockwool but we feel granules is a bit misleading. Floc is more small bits of fluffy rockwool than granules.
Bags are compressed so they take up less space than when you use them. 1 bag should be around 110-150litres when fluffed up.
Over fluffing will mean the floc will collapse a bit when watered.
Growool floc for the win
By: Seth E on
25 February 2022
I'm a satisfied user of Growool floc. Very satisfied. I like to start seeds and clones in cubes and then pot up.
I'm becoming a fan of fabric pots, even the large ones, up to 100 (US) gallons with the floc.
Remember to treat initially with pH 5 water and/or 50% nutrient (pH adjusted) and best left overnight
Also, be aware that you can reuse the floc until it physically collapses. Just pull out the old stems and replace the plant/s.
Growth can be explosive, in or outdoors. Great results. I recommend run-to-waste, with min. 10% runoff.
