Solid 5. This is hands down the strongest of the OG strains I've ever tried, and if the dispensaries around here get it in again, I'm grabbing as much of it as I can. This hit hard and deep, and knocked me out within a half hour. That has NEVER happened to me, very few strains work for my insomnia, unfortunately. Mostly that's because I have several causes for my insomnia, and no flower until now knocked all of those causes out. Can't say it enough: This strain is the strongest OG I've ever tried (and I've tried a LOT), and is NOT A GOOD IDEA FOR A BEGINNER!
