whats the temp. usually?

u should soon start fertilizing as well. strenghten them up. U also may wanna do some sort of training. U could top them.

I would suggest u get a light timer and give the plants some order in their day. 18/6 or 20/4. just don't do light all the time. Plants are part of nature and nature rarely exists with 24 hours of light a day. Ur job is to creat an environment that a plant would normally grow in.
