I do find it difficult to choose between phenos, I usually run each one at least twice, sometimes in different media. I haven't had too much trouble with quality, just choosing between 2 great ones! I ran 2 phenos of Querkle for longer than a year before axing one! I have had trouble with a couple of TGA strains, JTR, to name one.... I really wanted that to work out, but, there are so many great varieties of cannabis on the market now, I haven't tried her again. I have been wanting to try Jillybean for a few years now, but it was always out of stock. Needless to say I can't wait to try her out!(I have never come across Jilly in finished form!)
