Well, about 18 days from seed, and I officially have my first 12/12 contender. This is a bagseed, pretty sure it was Lemon Kush.
I have 2 White widow that are about a week behind the above plant.
I also started these white widow clones from a plant that was about 2 weeks into flower (after 6 weeks of veg). They've been under 12/12 for about 10 days. I just noticed 1 single root on one of these today. These should make for some bushy 12/12ers. There's actually a 3rd clone that I started today after I broke a branch from another flowering plant
