I didnt really follow a time frame with the cut. It was about 8 inches tall and right between the 6th and 7th set of leaves. Betty 2 was started outside. I looked last night and it seems as if the plant hasnt even grown taller below the cut. Its 7 inches then it makes a Y. But the two heads are 10"inches now from the Y and branching like crazy. So 17" in all, still in veg and getting bushier and the stem is getting thick like a finger. You want pics? Here you go!
