I run my Veg Tent anywhere between 70 - 80 F. Sometimes it gets to 86 F. Not that big of a deal until you hit 90 F where you need added Co2. It's just harder to keep high humidity with higher temps. I've ran all through Veg with 35% RH before with no issues. That could vary by the strain you grow though. Most of the time I try to keep my RH at a minimum of 45% but prefer 60 - 70%. These plants can withstand a lot.
Think about this a minute : Are the Temps & Humidity the same day after day outside ? "NO". But the plants keep growing. So some variation in temps & humidity wont hurt anything. You just don't want sudden drops of 10 degree temps.
During Flower I run my Temps at 72 - 77 until I see pistils. Then I drop my temps to 68 - 72 F for the rest of Flower. The plant thinks it's winter & sends out protection in the form of Trich's. Also helps to change the color (Blues, Purples, etc.) in the leaves.
I'll be lowering the Temps on this one in about a week. She is just now putting out pistils.
