Regardless of the proven benefits I would still feel like a friggin dink telling folks that I pissed in a cup and measured out exact amounts to mix with water to feed my plants. That, and it does not matter to me how short of a period it takes for the stench to dissipate. The smell of piss is not something I want to live with for any amount of time. For all you folks that use pee-pee on your ladies, go for it but count me out.
Ahmen my friend. Nicely put too. Human urine is very acidic and would make the PH of the soil go nuts. Even if it worked, it wouldn't be worth it. Plus, I wouldn't want any chance of my harvested buds.. i wouldn't want any chance of them smelling/tasting like piss. And yes, even after thoroughly flushing the soil.. your still going to have buds that smell/taste like piss because of the high acid content of human urine. Even if you flush the soil, its going to be too late because the plant will have already taken up the urine, therefore its already in the plants system (the stems; leafs; and of course, the buds).
If people want to go pissing in the plants soil, let them be. But I will not nor never ever, use piss to "fertilize" my cannabis plants. Never.
It's just not a good idea all the way around... despite those people that swear by using it. Just not a good idea.. I would just stick with regular fertilizers and nutrients... and skip the whole piss theory.
But, for those of you who still plan on using piss.. on your plants.. good luck to you because your going to need it... IMO.
Peace
