Thanks, I am trying to find the right VPD, but the RH is hard to control. I had it easy from september to now. Been cruising in the 50-60s on several winter grows, but now its summer and I need to pay closer attention.
Still learning, and mishaps makes for good teaching. My plan was to not grow in the pesky summer, but a sativa dominant photo decided otherwise.
Also, the Scrog is a first, and the canopy was too thick. Now it looks much better, airier, and 6 120mm fans blowing up from below, and a oscill stirring the canopy.
Same setup, a january-to-april-grow, with this photo and two autos, one bushy bush, never went above 60%, no dehumid. Best nugs I ever smoke, and will never run out
