Had something that tasted like blueberries a couple of weeks ago, so Ill just call it Blueberry Was really tasty, and a nice sativa high. Went to a Media lecture stoned off it, and ended up writing 4-5 pages... cant remember any of it for the life of me though!
Had an ounce of Durban Poison last year, and that was incredible.
And a couple of months ago I was lucky enough to get 5 grams of White Widow and 5 grams of White Rhino. Out of the two I preferred the WR, not because it was a heavy indica stone but because after a spliff I just didnt want any more! Not that it was crap weed, but I felt like Id had my fill of THC for the day. The WW was tasty, but it kept making me go back for more. The WR lasted me a few days, whilst the WW only lasted me a day lol.

Those are the only strains that Ive had that I know the names of. AK-47 is apparantly abundant around here most of the time though, so Im sure Ive smoked that before.

Edit: shit I forgot about Lowryder lol. Had that before (my own homegrown), and while it isnt up to the standard of DP, WR, WW etc its definately not to be scoffed at. Very, VERY nice high but sadly doesnt last long
Wherever you are in England, 3.5g of weed will cost ya £20, but at the moment its running at £25 because of the drought.
