ak 47 is like the knock out smoke as you were talking about.. if you smoke a fue bongs in a row you will feal like a bubble when you walk thinking that you are about to hit the floor, i made hash out of ak before (the sledgehammer technique) and i came real close to a blackout, luckily i did not green out on the floor that day.. it's also very easy to grow and grows very well outdoors !

blueberry is another 1 of my favorites because of it's amazing blueberry smell and it smells more potent than real blueberries lol.. this weed will instantly get you high as a kite but i find the stone is short lasting and it usually runs for $70 - $80 a quarter around here so your better off growing it or buy large quantites.

grapefruit - my favorite known strain (i have smoked 1 other kind of weed that i like better).. it has numbing/floating/tingly effect that seems to last for hours (i woke up baked before with this weed) and the buds are either green or purple but i think both has the same berry like taste this shit went for $320 an oz when it was around and dank weed such as blueberry ak and others were 200 an oz. someone i knew grew this strain last year and still has a big bag of it left
