I run a 4x8 durafoam room that’s vented in my garage, no ac but 1/4 hp chiller
I’m in Chicago, have 2 40 pint dehumidifier that put out a fucking lot of heat
Plants are doing great, it’s nuts. Nothing like heat stress when I grew in soil
I’m in Chicago south burbs and I get temps of 93F but I’m also running co2 where higher temps are recommended. Inside of a garage dam that’s gotta be tough right? Seems like you would have major fluctuations in RH and temps
I had an attic grow room (no heat, no A/C) that I used in winters, years ago. One grow extended into May and it hit 110 F a few times during the lights-out period.)
I'm sure yield suffered, but the plants looked just fine. It must not have been 110 for very long. I had one of those hi-lo thermometers, so I have no idea of the duration of the stress.
