I live in a somewhat strange area, climatically. One November, I was on top of a local hill with a couple of radio techs and a deputy from a nearby county. A couple of guys rode by on mountain bikes and the deputy said something about trespassing... very common thing in that area. I said they were probably just going in to check on their crop. He said the frost would have killed it by now. I informed him that we didn’t get frost on that hill because of the nearness of the ocean and some peculiarities of the evening thermals. He turned white as a sheet and looked like he was gonna barf.
Eliminate the black market, and there won’t be such a thing as bag seeds. Legal weed is sinsemilla - female bud that has not been pollinated.
