Should one poke a needle through the stem of a flowering plant?

Actually peeing on your soil when they are growing isn't a bad idea. I heard that our pee is a great source of nitrogen. As far as stressing the plants, if your not careful it will stunt your growth. I am sure that there are some good low stress techniques. But I would only try using those a couple of days before harvest. It would increase resin production, but decrease bud mass production. Also I heard that 2 days before harvest that you should stop watering and 2 weeks before harvest stop feeding fertilizers.
