right now i dont have any over 2ft tall at the moment and most of them probably only have 3 weeks or so left so i know i wont be able to make a differnce on this round but for future notice, i was wondering what has to be done to get them between say 4-5 ft. my set up is a 600HPS, soil garden, not for sure what size buckets they are but im pretty positive they are big enough.
