We're a mostly plant based household and try to use veganic practices in the garden as much as possible, so I've never tried fish fertilizers. I know a friend of mine swears by it though LoL
I've heard great things about composted seaweed and will definitely be trying that when we head back east! :]
For nutrients we use compost mainly, it seems to give the plants everything they need.
And there's always pee for nitrogen!!! haha It's sterile and has a ton of it! :P
Oh right I remember you told me that. Saving water at it's finest =)
Haha hell yea! Works like a charm!
