Yes, I grow a few of all I have in stock which makes for different harvest times usually but also leaves me with a nice variety so building up tolerance is all but unheard of in my home. If you have the space (and balls) go with half-a-dozen of each so you'll have a better chance of getting that rare keeper that pops up every 100 plants or so. But you have to plan for half being males, a few 'failing to thrive' and some for your friends. I plan my plantings so if 25% come through as females and healthy enough to clone and continue through to harvest then I'm doing good. But then again I'm pretty picky...
