I just keep vegging them till they're large enough and top them twice on 3 locations and then set them on 12/12. After 10 days of 12/12 it should be possible too recognise the males within the plants.

I'll remove the males and the weaker females, take the 9 best females out of they're devided space (pot). I get the deviders out of the bins and plant the strong females again. After that I'll put the scrogg over the plants and let them grow thru it during 12/12.

Then I'll keep tying the plants too the net untill they've stopped growing on 12/12.

After that it's a piece of cake if I can keep the temps in order
