They have a Cannabis Cup ideo out that is worth watching that explains how it is done. It is pretty interestinghow they do it. I thought the same way you did but it seems like they can do it. Plus it has a lot to do with people visiting for the week, they cast a vote for what they want to win at each coffeehouse. That is part of the reason they say Greenhouse Cheats, he'll stand on a corner giving out free joints to everyone while the other brands you have to go in and pay for, so are you going to vote for the guy that makes you pay or the guy that gave you free joints ? I'll have to look up the name of the video, it is pretty good to watch.
