I have no idea where this would go, but you are the best group of people I can think of to ask this.
My mother and I were thinking of having a hydroponic garden of the DIY type. Before I was into it until I was like, wait, fertilizer. (I don't know what my problem with fertilizer is. I think I'm cheap.) She wants to have it with fish instead. I had a basic idea down for it, but it wouldn't have enough room for fish. It had maybe two gallons of water in use.
So does anyone have any ideas for this? We don't want a HUGE setup. My idea had maybe 3-5 plants for it but more is okay. I have eh-level of experience doing plumbing type things, but I have a plumber and electrician held hostage. The setup I was looking for used an air pump like for an aquarium, which I already have, but really isn't necessary if there's something better.
Is there also anything we'd need to know for health related things? I mean, poo-fueled fertilizer always has the opportunity for disease and all. Chances are though, I might not actually eat anything from it, and might have flowers or something.
