Grow room tempature

[teamgilly]

my grow room is actually hotter while the lights off then at night when the lights are on. around 90 right now cus its so damn hot this summer. is this odd and will it affect the plants in a bad way?

Pot is hearty, but growth slows at high temps. Good ventilation ls the easiest quick cool.

You could also think about adding CO2 to help the plants adjust better to the highr temp.

i've heard of people using dry ice which is CO2 basically frozen. It evaporates at about 7% a day in the freezer. Don't know how much it cost? Maybe place a small amount in the room. You don't want to exceed 1500-2000 PPM(i think might want to research the exact numbers). Also you can spray with seltzer(salt free)water, which is just water and co2. Not the cheapest option, but prolly the least amount upfront money. I have no idea what a co2 reg and bottles cost, but you could check your local welding store. i am still like at least a few months from even thinking about a co2 system so I have not done any serious research. Good luck. Great question, common problem.
