That's one of those only every 3 - 6 months type strains. Most potent I've seen around these parts though. I only know the THC, which was tested at 25% (he's a regular grower for the co-op). Doesn't matter how much/long I grind... I get that layer of kief. Except, almost that entire grinder packed full, its pretty much pure kief. The Mendo Mulcher will do that with under 10 turns. I usually only turn it once, each way then dump and its still almost too fine for my HI. I ground the last of it up, specifically for the MFLB, like saving some of the really special stuff for the Box, every time I get some.
