Do you actually know this person and seen his grows? I seriously question whether urine has enough nutrients to take cannabis plants through flowering. What is used for nutrients if he doesn't use urine? How does he deal with the smell?
If a dog pees on your grass it will leave a brown spot where the grass has died. Raw urine has a high salt content. I have heard people using diluted urine as it does have some nutrients and good bacteria in it. This however seems to be very shaky and you could kill your plants. Myself, I will stick with Fox Farms and EM-1 Microbial Inoculant.
In 2012, Kim Nace, Rich Earth’s administrative director and partner Abe Noe-Hays collected 600 gallons of urine from friends and neighbors. The next year, the organization brought in about 3,000 gallons from 170 human volunteers. Rebecca Rueter, a board member for Rich Earth, invited members of the local women’s chorus to donate their pee.
Rich Earth hopes to double that amount this year to a round 6,000 gallons — enough to fill a third of an average American swimming pool. “We’ve given volunteers a few things to make it easier — some funnel devices and things like that,” says Nace.
Urine contains nitrogen, phosphorus and potassium — essential plant nutrients that are usually mined from the earth or the air for agricultural use.
The project aims to test human urine as a replacement for chemical fertilizers.
We do not use feces from animals that eat meat (including humans) as their feces general carry pathogens and parasites. That is why they are not put into compost piles. It is different with the grass eaters.
