super silver haze auto space question

heres a super silver haze at around 45 days
duna grow
protect
in a waterfarm
3 55 watt Cfl
2 26 cfl
I uses bloom bytes to try to stop her from growing im running out of space, I dont want to build another Box...so far this one Works perfect with no smell
any suggestions on how to limit growth?
I dont want to use strings
I think it to late to do anything

how did you get her to grow like that. i have silver haze also and mine has been growing 4 week and nothing near that size
