Hash question first.........yup, I actually started them with hash. I’d let the pot dry to the bone, then use a screen to scrape the hash off. Mostly secondary product though, trim and lower buds not fully finished. It’s tough to judge the correct amount to use though, it was definitely 4-6 grams I’m guessing. I felt the buzz was a little more uplifting too- but we are talking years ago, maybe 10. I don’t bother with hash much anymore, as I just throw the trim and crappy stuff out. Too lazy these days to do the extra work.
Regarding a recommendation, when people ask- I usually recommend Holy Grail Kush from DNA. Easy to grow, solid yielder, stinky as shit, great Kush buzz and no hermies. It got high marks in every category. I’d be growing it if it wasn’t such a stinker. There’s tons of others, that one always comes to mind first. Next would be Mr. Nice’s Medicine Man, another great plant but no feminized version. I strongly recommend either one for a high yield grow, with a top notch buzz.
