well yea I'm vegging them still and going to vg for another 2 or 3 weeks for 2 of them, the small one in the 1 gallon is going to flower soon, it was the first to root and show new growth, cut one week ahead of the others. But that wasn't my real question, my real question is...

Compared to seed, do clones use the same amount of root space to grow the same amount? Or do they use less root space than the plants from seed to become just as big?
