For those who may not know the meaning of the word, guano = shit. And people use animal shit all the time. A lot of the better soils come with good quality shit mixed in. If animal shit is good, I don't see why human piss would be all that bad. I know when I smoke a bud, it doesn't taste like bat shit. Well, actually, I have never smoked bat shit, so maybe bat shit does taste like kickass bud...but I doubt it.

That said, I have never felt the need to pour any quantity of my piss on my plants, however diluted. I give 'em animal shit and leave it at that. Heh.
