haha, thanx. I used to always wet them alil giving kind of a mold to it so it doesnt break apart easily incase the roots haven´t really started makiing that mold themselves (especially in the earlier transplants). but i like ur reasoning

Well ya, spin-out is classified as a chemical pruner but i really wouldnt say it prunes the roots. You paint the inside of the pots with this copper hydroxide mix; the roots grow and just before touching the sides of the pot they turn around, never entering in contact with the chemical. these plants are said to have more roots and more evenly distributed throughout the center of the pot, making them easier to mantain and allowing them to last longer in there pots before needing a transplant. I just think about the possible protection that the roots have when they are not in contact with the bottom or sides of the pot.
