Low humidity has been an issue this week so the HPS lights has to be turned off as they were reducing the humidity down below 10% and the leaves were suffering. The 600W vipar LED equivalent is doing a great job and the humidity its holding steady at 25%.
I have misted the tent walls a couple times per day to boost the humidity and increase healthy leaf growth.
I was lucky enough to acquire some old Feminised 1996 genetics of the Purple OG kush pheno.
