So I am trying to use as much free organic stuff as I can find. I heard spent coffee grounds are a good source of nitrogen.
I just went to star buck and got a bunch. What exactly do coffee grounds provide- just nitrogen? How much should I use and should I just put a layer on top and water normally?
Are there any other easily available free stuff I could snag somewhere?
