i used urine years ago on a plant. it gave me some strong ass bagseed bud. i never took care of it for real. whnever i thought about it, i jus went to the backyard and pissed. i gave it tap water a few times. but mostly urine. plus it was inbetween two thick rose bushes.i only got two blunts dry bud out of it. But the shit had me high for hours. and it was purple. im want to experiment with one or two now. but i dont want my crib smellin like piss. dont have outside ventilation right now. but im gonna do it one day.
