My grandmother and grandfather used to live in the Mat-Su valley years ago, when my gramps was a state trooper. She said they used to plant them in trash cans, use the summer as a free veg cycle, chop down the boys in August, and roll them in to a barn on yard carts, finishing them under 1000w MH. That was the best light they had at the time. It was 1960's pre-prohibition Alaska at the time. At one point gramps brewed a big batch of ale from barley, hops, and cannabis. He called it "This Buds For You" and put a small flower in each bottle before cellaring.
edit/ One crop a year. My grams was big on "Christmas Buds" and by the time I was a late teenager there were always tiny wrapped fun things in my stocking. Nugs, pipes, whip-its, peyote, shrooms. Grams was a f*ck!ng riot. Of course by the time I was growing up their orchard days were long over.
