For real though, it should be common knowledge that urine diluted in water is great for plants... I just think it's gross, and I wouldn't do it on something I was planning on putting in my body.
Yeah, I'm positive I read somewhere in Mel Frank's Marijuana Grower's Guide the proper use of urine. It was written in 1978. It also outlines the use of incandescent bulbs and aluminum foil as a reflective material. But it also tells you how to dilute the pee, and says that flat white paint has more reflectivity than aluminum foil and distrubutes light better than foil. So it really depends on how you read, and if you read everything. I read that book as my first knowledge, on my first outdoor crop. I tells you pretty much everything you need to know to be an excellent grower, I've read through over and over. It's a great book and I recommend it, even though it's outdated material.
