theres lots out there on that and it depends on your strain, you really dont want it dropping down more than 68-65 at night and anything over 80 will start to have a diminished return. However that changes with CO2, as far as humidity goes, you dont want allot because it can rot your buds.
I should tell you that this is all stuff that I have read on here, I am early into my first grow, but I have been reading for a few months now.
