Urine is awesome it's sterile, organic and most importantly FREE, but mostly it's good for vegging cause of the high nitrogen level, so maybe there is another alternative to store bought fertilizer, that would work in hydroponics.
I heard that bone ash and wood ash are good for it, but can you use it in hydro?
