I love 90% of it... the arms creep me out a little bit

Mostly just the other set of partial arms creeping off the bottom of the tray, everything below the elbows just looks so wrong
youre probably going to end up wishing you planted those further apart lol. But it is already June, so maybe not, but ill bet probably. Depends on the genetics lol.
depends entirely on the flower.
If its a well cured dense little og kinda bud at 60% rh or less, and its going in a pipe or a bowl, yea ill grind it if the grinder has been kept relatively clean.
Its its fluffier buds, or im rolling a doobie, i just stab that shit with a bobbie pin or dab tool while holding it between thumb and finger until it falls apart then roll it up lol.
most of the time, no, i dont use a grinder. i like my stab it til it falls apart method, it doesnt leave any kief behind, and you dont get a bunch of skin oil either, and i dont smoke constantly enough for that to be a real inconvenience.
