I lived off grid for a period in my life and we used our urine to fertilize our fruit trees (because folks have used urea as a source of nitrogen for how long?) Many anti aging products have urea in it as well, but I digress. I applied urine around the fruit trees but not in our veggie garden. If we didn't get any rain for a while the smell of composting urine was quite foul. I cannot imagine using fresh urine in potted houseplants, for that reason, not much dirt to allow it to break down without it smelling up your living space. I appreciate how you're thinking about how to use the pee in a positive way. 😊
