Works both ways fella. Certainly on the outward appearance cheap would suggest it's crap, but all you need is to make one sale and make one buyer happy and it all goes from there so long as you are a consistent grower. That one sale though, he'll tell his mates, they'll tell there's, and soon the entire neighbourhood will know that great weed can be bought for a great price. It's simply a matter of doing the marketing to get the first guy interested in buying, which could be in the form of say selling on someone elses weed for the going rate, and then throwing in a free 8th of your own better stuff and mentioning that it will be available soon, they'll smoke it, ask what you'd be charging and you say £160
It's not hard to undercut competition if you have the willpower to do it. What am i saying though, i know all you lot, you'd sell it for £300 if given the chance
