I had a neighbor who was like 50 when I was 15.
Really cool guy, very old timer.
He was growing 5 plants in a butter bucket.
He put soil from a local park in a butter bucket, took some shitty reggie seeds he had for years, put it on a fire escape with little to no direct light.
I swear almost a year later, they were all alive, but they looked like shit. Each plant was under 7 inches and had like 4 little calyxes of bud on each plant.
Funniest thing I ever saw.
