I live in the UK, but not in England. I'm suprised to here so much about the shit weed there. As it's definatly not that bad here in South Wales. I've smoked Shiva Skunk, NYCD, Chronic, Love Potion, Black Jack, ukcheese, Himdu Kush just in the last month or so. And that's from the local guys i know. And doesn't include what i've been smoking that i've grown myself.
I've only ever come acorss sprayed bud once, and that was when it was really dry for about a month, and we had to go outside our normal circle. The only average stuff we have about here is what we call "Chinky Weed". But even that is usually dry, and is not a bad smoke, just nothing special.
What's even more weird is paying over £140 a ounce here is considered expensive. And the prices don'tvry hardly at all depending on what you are buying. I could buy a Q of Chinky for £30, and a Q of Black Jack, NYCD would be £35-40max.
I agree with everyone who says stay away from soapbar. But i'd go further and say stay away from any hash in the UK, unless you know the person who made it, because no matter how much people tell you "this is pollen!" it is never anything like what i've pressed myself, so is definatly not pollen, and i dont think it tastes nice.
Maybe i'm lucky with the few people i know and mates who grow. But my mrs mates boyfriend is a rasta fella from London, and he comes up to see her and brings her weed. And what he brings up is very good and very well grown.
I think all you need is to find and be friendly with decent people who grow or sell. Decent people who aren't all about emptying your wallet for as little weed as possible. It might take a while, but i am sure there must be a hell of alot of good growers and weed in the London area. But i guess the English would know better.
