I just read an article over at cannabis culture about a contest they did, where all the weed to be judged was grown by a single grower. this obviously eliminates a lot of variables in the product to be judged, and introduces the possibility of judging categories not possible in the more "open" approach used by other competitions (for example: yield) I recognize this would not be simple to implement. to find a grower with the capacity to handle such a task, who is also trusted by everyone involved. I'm not saying it's a be-all and end all or that the "open" approach is worthless, but there is always room for a discussion of ideas and different approaches (except, perhaps, in the middle east)
