Ok so Ive got about 7 plants that have been in the veg stage for a few month's waiting to identify the sex. Just to refresh I read up just now and saw you have to put them in the flowering stage to tell the gender. Well my plan was to keep a couple few of these in perpetual veg for mothers. So how is this possible if it is neccesary to take them to the flower stage in order to weed out the males?
