Raising temps lowers humidity.
Early veg 70% RH is perfect.
Temps should be around 26⁰C in early veg with lights on, 0 to 3⁰C lower of a night.
When your plant gets larger RH will rise. You'll need a dehumidifier to get it down. You'll need under 60% in early flower and lower later in flower, around 40 if you can.
Any dehumidifier you get make sure it has a capacity of more than 6 gal/day, anything smaller wont do much. I run a 13+gal/day with two air conditioners and it just copes with flower yields of 4 to 6lb.Flower Room: 11' x 7' x 7.5'H, 480w AC, 13gal/day dehumidifier, 1.5gal ultrasonic humidifier, 60gal (27gal usable) nute tank, 16" pedestal fan & 18" wall fan.
