Anyone managed to make homemade Hydro fertilizer?

Hi,

Is that all you used? Just Urine with nothing else? I actually heard it somewhere but thought it was a joke. And does it have all necessary n-p-k?? I'd appreciate more info if possible.

Thanks.

Yup, ive used my piss as a hydro nutrient mix

For being free it worked great. All you have to do is watch what you eat!
