This is a small aquaponics system I built so I could experiment with the concept. If it works out well for me I'd love to build a large version of this system but before I do want some working knowledge of how it works and any problems i might encounter before I invest a lot of time, effort, and most importantly $$$ into it. This way was a cheap and easy way to gain that knowledge as well as a fun little project. I also want to see what will grow well in the grow bed.
