I found a book about growing with Urine

"Liquid Gold shows how urine is used worldwide to grow food and landscapes, while protecting the environment, saving its users the cost of fertilizer, and reconnecting people to the land and the nutrient cycles that sustain them. That's real flower power!"

did some more research on the use of urin with plant life.

USEPA water quality specialist Tom Faber composts and grows with Urine.

Urin is commonly used to grow in Sweden.

Studies that show the science behind the practice that using urine for fertilizer is a feasible, safe, and cost-saving way to prevent pollution and save on fertilizer costs.

Author Carol Steinfeld is projects director for Ecowater Projects, a nonprofit project that informs the public about ecological wastewater management solutions. She is the co-author of The Composting Toilet System Book and Reusing the Resource: Adventures in Ecological Wastewater Recycling. Her articles have appeared in The Boston Globe, San Francisco Chronicle, Natural Home Magazine and many other publications.

Human urine makes an excellent high nitrogen liquid fertiliser for most plants. Dilute it 10 to 1 and pour it over and or round fast growing plants once a week; like vegetables, Green manure crops and sugar cane. Indeed just about anything that you want to push along rapid green growth

Studies indicate that each personâ??s waste fluids can provide enough nitrogen, phosphorous and potassium to grow a yearâ??s supply of wheat and maize for that person. According to some studies, human waste can be an even more effective fertilizer than animal manure.

Urine, which comprises 90 percent of human waste, contains about 80 percent of our wasteâ??s fertilizer value. It can be applied to field crops without treatment because it is generally sterile. By the way "fresh urine" does not contain any bacteria, unless the person has a urinary tract infection, so you could even use it to wash out wounds without causing any infections,

Human urine can be used as an alternative to chemical fertilizer to reduce pollution in air, water and soil and help avoid or control other environmental hazards which surface due to the use of chemical fertilizer, Human urine contains nitrogen, phosphorous and potassium at a much higher ratio than in commercial fertilizers and is environmentally safe to use.

In a Hydroponics set-up, use it diluted, probably at a ratio of either 10- 20 to 1(water- urine), but keep a close eye on both the ph level and the level of individual salts of the mix in the nutrient storage container.
