Too hot better than too cold? High Ph better than Lo Ph?

curious. for exampe would it be better to have the average temp be 70 or 80? and pH questoin?

I would rather have 80 degrees, if your humidity is around 50% or lower.

i have 25-35% humidity. so its safe to go 80?

Recomended temps are between 65degrees and 85degrees. Anything out of this range and plants stop growing until they are back in that range. Optimal for hydro is 75degrees 78 max. 25-35% humidity is very low. Recomended for veg is 50-60% and flower is 40-50%. If humidity is low the plants tend to be less bushy and stretch more.
