Does anyone know the best way to keep H20 temps to desired levels? I have a current garden in a CGE and the lights on room temp is from 81 to 85 degrees. The water temps in the BBs is the same. Right now the plants seem to be thriving but my water temps are at 83 degrees. It is my understanding the optimal temps should be from 65 to 75 degrees. The warmer temps will probably affect the yield which I don't want. Any ideas GC? Thanks
Aside from a water chiller you can stick a couple dozen bottles of water in the freezer then throw 'em in your reservoir when frozen then put more in the freezer and keep rotating the bottles between freezer and reservoir.
