I like to keep a couple mothers in coco under a T5 light and clone everything when they get big. They are basically sacrificial mothers because I take everything from them, save 2 or 3 clones for my next mothers and the cycle keeps going. I then pack anywhere from 2 to 3 plants per square foot, SOG, and flip them to 12/12 after a 3 day veg. It can be just as quick as autos.
