OK, I let my girls go waaay too long in veg and now have some monsters on my hands. I cannot imagine what they will be like after the stretch!! There is going to be so much wasted space it makes me ill. I am sure nothing below the top 1/4 of them will get any decent light and produce anything worth the time and effort from me and the girls. Should I cut all lower branches before switching? Any ideas at all would be greatly appreciated, as I am running out of headroom really quickly also. There are about 35 of them under a 1k hortilux, and they are about 48" tall now. Thanks in advance!!!
