While looking for that stapler....i had a brain fart. What are the ideal temps without co2. if one were to top out at about 80f, then down to 65f at night, I'd think that's fine?

thats where i keep my room and all is good so far but at times it goes above 80 could that be bad for the plant ?

Well considering a grow can work in 95F temps (not well though) for like 2 months without co2, i'm thinking a little over 80 wouldn't hurt, but i'm determined that 82f is the limit

I keep mine 88-80 in summer and about 80-70 in winter. But I don't think anything over 90 or below 70 is good. I just use that as a general rule.

if my grow box was to get over 85f during the day do u think it could cause my leaves to curl and yellow?

No. But depending on how close you have the leaves to the lights and where you thermometer is placed you still may be causing heat stress to the plants. It is a possibility but 85 is not really that hot.

Yeah well mine reads close to 90 sometimes when I know that can't be completely accurate and everything has worked well so far, still healthy plant etc. :D
