#numbered as the 5 seeds popped:
#1) massive plant thats very strong, she was easy to clone with indica genome but sativa hight and thick stems (looks like a big indica) lots of arms.
#2) she is inbetween #1 and #3 more like #1 than #3 but medium hight, start of shorter arms not as easy to clone.
#3) massive like #1 but sativa genome and again not as easy to clone and droops easy.
#4) exactly the same as #2.
#5) tiny too compact arms struggling to reach net struggled getting clones as too small. could be waste of space tbh but no decision until crop.
all had good roots but can be sensitive my next step is to remove any arms that have not reached the net and any growth on arms below arms cola, this includes damaged leaves not healthy, this will stunt growth for 2 days but the idea is to push the energy too the buds closer to light, it takes alot of energy from main buds to bloom;these lower buds, so removing them makes her concentrate on her top buds and cola.
id class them as a medium skill level.
It is supposed to be on 24 hours. Can you turn it off during lights out? Probably, or you could turn it on a couple of times during that period, but it will always be best to leave ir on constantly.
