Some years ago I was telling a dude bit about a trip down the highway, one area I smelled our favorite smell. I was on the job no time to stop and look in the woods., on the way back both sides of the highway were lined with LEOs and going into the woods in the direction of the odor. Certainly did not stop then, later I am telling this to a dude I had just meet, he said it was his patch. But this is where it got odd, and at that time I thought he was pulling my leg. His claim was he had crossed MJ with Hops to make a MJ vine, he laughed and said they will stand in the patch with buds hanging from the surrounding trees all around them, and never find it.
Skip ahead, its now legal here and I get online and start doing some real studies to see how far behind I am. (a long damn way). I find articles on grafting MJ, and grafting MJ to Hops, then I find articles on crossbreeding MJ to Hops. It seems one must alter the hops head so the MJ pollen can get in, and they will cross (they are cousins), and can make a MJ vine or a hops bush. Stealth would only last until its found out.
