Need a little advice here. I built a 2x2x2 grow box with CFL's. The only logical location to put it was upstairs of my garage. At night the temps are dipping into the 20's (farenheit) and was getting too cold in my box. Anyways long story short I wired up a heating pad to a thermostat and am now able to maintain 50 degrees at night, even when it get real cold out -last night was about 15*.
Is there going to be any plant damage at 50* (auto's, green-o-matics). I know growth will slow down, which I am ok with, I just dont want to kill my poor girls. Right now it isnt a big deal as I have them in the house unde a cfl untill they get a little older and am running the box right now as a "dry" run so to speak.
I have 4 26w CFL's, exhaust fan and a fresh air intake routed to the downstairs to the garage so on hot days it pulls in cooler air. This is with a 20/4 cycle, fan and lights together so when the lights go out the fan does too.
