Root zone vs. air temp
Hey all -
I am growing lettuce indoors (temporary until I get the greenhouse going) and wanted to see if I could reduce my costs a little. Does anyone here think that I could let my ambient temperatures rise (84F or higher) if I chill the nutrient tank to a constant 65 - 68ish F? I am using NFT and it is killing me to run AC all the time to keep the environment cool. All inputs welcome.
