I'll bet you there's a way we could make wine from that.Since piss is high in Nitrogen, yeah you could use it. I did, and for the first couple of days, it was ok, then it (the piss in the soil) startd to smell. If you never smelt fermenting pee, consider yourself lucky. It being an indoor growroom, it stunk for quite some time, but yeah there was a noticeable improvement in the plants which were 'pissed' on.
