heres the problems I ran into when using the tent.
1) heat issues using a 400 watt MH, I was never able to close the tent because the temps would sky rocket.
2)plants are hard to get to after first row.
3)6/8 plants are max(not LST/clones)
I grew out of my tent(got 15 plants going) but I'm still using the frame of the tent to hang my light on-comes in pretty handy.
the tent is a good buy if 1-2-3 is not an issue for you.
