Very true Green, however, as is my case, and Mogie pointed out "you may realize you want to perpetuate a plant you neglected to take cuttings from." Also, you might think this is easy, and it really is not 100% from what I can see so far, I started with re-vegging 4 plants, and my success rate so far looks to be 50% but could drop to 25%. Have to wait and see.
