What is the proper humidity for growing?
40% - 60%. Higher in veg, lower in flower.
If you can control it you're in luck.
Prior to this grow I was a steady 40%.
Here at the new pacle I am 50 -55, which is higher than I prefer, but there is not a damn thing I can do about it.
Can a higher humidity during flowering lessen the yield or density of the buds? Or just cause a risk of mold?
Lights On - 75%F -60%RH
Lights Off- 70%F -60%RH
Those numbers are optimum but I go with what I can cost effectively get close to that.
