Dont agree but anyways

read the below... dont know why people are associating the Urea you buy off the shelf with Human Piss or any type of Piss.

Heres the big difference.
Grey water (g/pd)Urine (g/pd) Faeces (g/pd)
Nitrogen 80 % (11) 10 % (1,5) 10 % (1,0)
Phosphorus 50 % (1,0) 25 % (0,5) 25 % (0,6)
Potassium 60 % (2,5) 25 %(1,0) 15 % (0,5)
Human Urine contains only 10% nitrogen (something you can get from the simplest fert)
Your dyluting this down by 15, that equates to less than 1% Nitrogen.
Urea off the shelf is 46%, giving the plant a huge boost in energy... I've tried the Pee crap and
have seen zero results from it.
