Dumb question, but taking prints from nice clusters helps narrow down genetics? I assumed all MS was random.
Yes, I learned that from mlbjammer (an old mentor and mod that has retired). It makes sense if you think about it.
A cluster of fruit has already expressed desirable, healthy genetics. One can assume that its spores are healthier too. It's a long game though, going spore to spore, printing exclusively from clusters over time will give one better than average genetics IMHO.
Of course there's a chance that one will end up with a shitty grow due to rando spores mating and crapping out or expressing undesirable phenotypes, but lemme tell you, every print that he ever sent me was bananas!
