people have been fishing for thousands of years. every once in a while, some one comes out with "the future of fishing" which will "change the way the world fishes forever!" they usually enjoy a small amount of success, before the world drops them in the tackle box with the ronco pocket fisherman and the floating keychain. why does the world drop them in the "trash" tackle box? because the process was streamlined before they were born, and it works.why fix something that works? why put extra effort into getting basically the same or worse results?
people have been growing weed as long as they've been fishing. they do it the way they do it for the same reason. it works. they've tried defoliation, they've tried molasses, they've tried fishguts, they've tried dancing in the moonlight...some of it works, and they keep doing it, some of its a total waste of time, and they quit doing it.
someone re-invents the wheel daily, while the rest of the world is busy rolling down the road
