I've chopped several of the LSD, and I am still growing a few. All the plants (all from seed, btw) have been basically the same pheno. Yeah, I agree the buds are weird looking. Very large colas, but very loose. Best way I can describe it is instead of the bud-shaped bundles of calyxes I am used to seeing it's more like these long rope-like strings of calyxes. Horrible desription but that's what it looks like to me. Really unique aroma too.
Very very potent weed..probably the most potent I've grown so far, but I've only grown about 6 different strains so far.
