Grape pupil V2 (the pink version) grows the hardest buds I have ever grown. An oz looks like a half.Genetics are biggest factor as others already point out. Big hard nugs don’t necessarily make the best smoke though. Dispensary weed, at least here looks good but it’s crap. No flavor, buzz is short lived. They only out for profits and most people care only what it looks like, or how high the thc % is.
