I am unfamiliar with the stability of other strains, but from what I've heard Dj's gear is some of the most stable on the market. To be honest with you, out of 28 females or so I found myself wishing for more variance than I got. I was doing a pheno-hunt but felt like I was growing from clone to a degree and personally it was kind of boring to have so many similar pheno's. But that was just my experience and like I was saying I'm not really familiar with the stability of many other strains.
What strains have you worked with that you felt were more stable than Dj's F5 Blueberry?
