Have you actually seen female preflowers?
Maybe give them another week. Then check them over real good for male parts.
As far as height goes.....they can grow 2/3 their size during flower.....Might have to tie them down or find a taller room.
Peace and Good Luck.....J
Skihigh Reviewed by Skihigh on . Plants refusing to flower Hi all, I've got a few plants growing on the sly under CFL, but the problem is they've been on 12:12 for a couple of weeks now and they look pretty much exactly like they did in full veg mode. They seem to be healthy as horses - in face a couple are nearing 3ft which is a bit of a worry as I don't have that much more height to spare. Should I be doing something else other than simply having them on 12:12? They get no light at all during the dark period. Thanks Rating: 5
