Rez temp much easier to control if you put it on a sheet of foam board in addition Weedhounds advice. If room temps are that low you have to get a heat scource and the space size will determine the best scource. I once saw a guy who did a grow in an un-attatched garage in the winter by hanging a tarp in a circle around the plants, bout 8-9ft diam. All he used was all the above with a small ceramic heater.
cannakeeper Reviewed by cannakeeper on . Reservoir Temps between 48 - 52 fahrenheit my reservoir is on a concrete floor in my ebb n flow set up. Temps in the reservoir are between 48 - 52 degrees fahrenheit. have been reading that reservoir temps ideally should be in the 65 - 70 range if I remember correctly. what kind of danger is there for my plants (currently 2 week old seedlings) with these low reservoir temperatures? what is the best way to raise reservoir temperatures?
