Switched to flowering 4 days ago on December 27th when the plant was 18 inches tall. In 4 days it is now 25 inches tall. It is really stretching. It is the heartiest plant I have ever grown. Thickest stems and biggest leaves. The manifold created 8 absolutely perfect tops. I cleaned all vegetation below the 50% line. It is a perfect flat canopy. Best training I have ever done.
