I haven't gotten to that point yet. I grow for the wife and I'm trying to find the best strains for her medical conditions (anxiety, depression, fibromyalgia). I haven't found the magic bullet as of yet, or even one strain that does an outstanding job at any one condition. Once I get something that she likes, I'll put it on the regrow list and can start cloning. Until then, it's new strains every grow. The Northern Lights in this grow is actually a regrow in a way. Its been one of the better strains out of everything I've grown so far, but it was also my first grow and I didn't do that good of a job with it. I'm hoping that with a proper grow, the wife will have even better results. Plus, it's been one of my favorites for "non-medical" use.
