Very bad idea, indoor or outdoor. Come on, ferts don't cost that much! Your boots won't be so fancy if you do such a disrepectful thing to your plants...
madeline Reviewed by madeline on . Using Urine for Fertilizer No joke, I've been looking into using urine for fertilizer. It's free and easy to use. After a little research was done the ratio of choice seems to be 10 to 1 of water to urine. The nitrogen in your urine helps feed the plants and it's free of course :D The watering down is to not violently upset the pH. Has anyone ever heard of such a technigue? Am I crazy? Please feedback of all kinds is welcome. Rating: 5
