For some reason only 1 plant is a different pheno and it’s so different it almost makes me think it’s a different strain. I know that’s prob no true and it’s just a different phenotype. All the other plants are ridiculously compact and is kinda difficult to prune and defoliate. But that’s something I’ve kinda mastered so it’s not a big deal. I’ve heard some people complain of mold with this plant and I can’t. See why. The compactness. Give it good defoliation maintain good air flow and keep ur humidity low and it really shouldn’t be a prob. If there is a mild prob these are weak genetics and won’t get them again bc my humidity is desert like rn. Almost impossible for mold or boyatris
