I have been running the same mother for going on about 3 years now. It has become far easier to clone, roots come in no more than 7 days. The vigor has increased, as I find myself cloning much more to control her. The plant has seem to "mature" over the years. The very tops have developed into a very nice ninja star, Shuriken type leaves, and they love to get skinnier. Also the fan leaves have developed from 9 fingers, to 11. She has also seemed to settle into a very nice bushy growth pattern, that makes it a dream to harvest. No matter how I try to shape the plant, it now develops into a shape it prefers. Too much manipulation brings down the yield. Potency has not suffered in the least.
