Temperature for Veggies in Hydroponics

Author: Scott  



Could you please tell me the ideal water temp in reservoir for growing tomatoes. I have it on 24 deg is that ok or a little high


Hi there

Best temp is above 18 degrees and below 25.

I usually look for 20-24 degrees over a 24 hour period.

So if its 24 at the hottest in the day, then it should remain above 20 at night…

Depends on the loss rate for your system.

Below 18 nutrients become less available, above 25 dissolved oxygen levels drop away.

Hope that helps.
