In the UK all I can get hold of easily is skunk. Sometimes I might get some other type of indica strain but its usually weaker so skunk is really the only option which sucks cuz I have only ever tried a sativa strain once and I thought that was way better.
Skunk is popular. Northern lights is popular. Past ten years or so has seen a wider variety appear. Now whenever someone has "good" weed...it's seems like a different strain each time.
Juicy Fruit, Blueberry, Sour Diesel, Sour blueberry, big bud...I've seen all of these floating around lately. Seen AK48 quite a bit...and will see lemon skunk and brainstorm soonish.
