TGA quarkle is probably the strongest indica I have ever smoked. I don't know if its going to be a one hit knock you out, but smoke a bowl and your ass will feel straight locked. Two bowls and you'll be passed out. Go to attitude seed bank, they have that strain in pick and mix for ten dollars, or you can buy a whole pack. Plus they'll give you freebee with every order. They are reliable, stealth sipping, and I live on the east coast and it only takes 8-10 days for delivery. Wait til the first week of october and on top of the normal freebee they give you they will also have a another special where if you order $50 you will get double freebies. Hope this helps. Good luck on your search.
