I've used urine (10 parts water, 1 part urine) for my organic grows previously and it works exceedingly well! It's important to make sure of a couple of things: you are physically healthy and you aren't taking medication that can pass through the urine. Other than that, urine has and is being used in organic growing of not only cannabis, but many other fruits, vegetables, and grains. While it might sound 'icky', as long as you're healthy and you dilute it down, it works very well. But then again, lots of what we use in organic gardening sounds 'icky'...bone meal, fish meal, bat poo, feather meal, worm castings (worm poo), etc!
