I have read about letting your plants flower for longer than normal will produce seeds. I have a few plants that I would like to try it. Does anyone know how long they must be flowered? Or rough idea. I was planning to put a small clone (enough for 10-20 seeds) put it in a 1 gallon off to the side and just wait them out til they get seeds. Seems rather simple. Has anyone done this or have any experience with this?
