Wellls, things have been going well. I've got all my girls in their 2 liters still. Anyone know if I'll need to transplant again or if these 2 liters will do?

The extra 2 liter you see in there are three 2 liters with frozen water that I cycle through when they dethaw to bring the temps down even more. It works really well. Been using the Fox Farm and it seems to be booming. They're not getting very tall, just really bushy, which is good because I want to keep them short. I also started LSTing them yesterday.

When do y'all think I can start looking for pre-flowers?
