hi
my 2 ladies are veging now for 5 weeks. after a lot of lst they are covering the surface of the pot (about 8-9 inch sq each) and have around 30 bud sites each.
i want to veg them to a big scrog, but what is the limit for a 15 litter (4 gl) pot , before they will get rootbound ?

i dont want the girls to get huge when they flower, and then suffer from root bound and lack of space.
so, what do you think ?
thanks .
