Thats interesting man and thanks for the tip. Id love to see a few comparison grows with the HS1 where 4 plants are gown under the normal 75-80F and the Rh at 60 or more for veg and then reduced to 40 for bloom. VS Rh in veg at 40% and temps at 80-85F like Brian says from Pro source.
One thing i can honestly say is i have never been able to get my plants up past 80F with out heat stress even with the new Hs1 and if im honest Brian from pro source didnt seem to be growing really monster plants. In fact the yield looked average or less and the buds werent that big so its hard to believe him.
Im not saying anyone is wrong id just love to see the comparison is all.
I have played with higher RH in veg but didn't get anywhere near the same size plants as I do now.
The temp in this room is just over 85f with no heat stress at all.
