I've been looking at #hydroponics and #aquaponics mostly for fun and because fresh green stuff is good. But good grief it's complicated!

I want something small, DIY, and cheap, that I don't need to remember my chemistry A-level for. But every "for beginners" guide I've found starts with a thesis on plant nutrition and I can't read it let alone learn and apply it.

Is there such a thing as a "My First Water Garden" guide? Something more the size of a pamphlet than War and Peace? With standard gardening you can get started with a pot of dirt and a bean. I can manage a little more than that, but not much.
