My nearest guess is that the pots theyre in now are 3 gallon bags that I've fenagled out of fabric grocery bags using a little sewing thread, a need, and a little ingenuity. My girls are pretty big right now. 8 weeks into veg, and still not showing sex. Though a buddy of mine says he see's indications of females... dominate indications. He's calling the stipules preflowers, and I do not see them present in some pictures of males, so he may be right, and I'm just a noob. Anyways, I'm wondering if I should consider transplanting the two large plants into full sized fabric grocery bags. I estimate those to be about 5 gallon, maybe 6. If I leave them in their current bags, aren't they going to become rootbound?
