I reused a fermentation setup for the hydroponic wasabi idea. I had some success with lettuce as a test subject but the humidity was not well-controlled which I think would be a problem. The thought of how much energy I'd have to use for years to keep the whole thing running just made it seem a bit ridiculous. Also, I'm not sure if I could reliably source wasabi seeds. I stick with super-hot peppers mostly which don't need a lot in the way of temperature control.

I reached a similar conclusion, luckily before doing too much building. I'm happy with terrariums so far, they scratch my 'living things in closed systems' itch.

Funny, I was sort of exploring the idea of aquaponics myself and I was trying to explain to someone what was at the root of my curiosity and I realized that it was enclosed ecosystems. I had fun giving the lettuce to people and explaining that it was grown without ever seeing natural sun or soil and showing them a timelapse video of the growth, but no one seemed all that impressed lol.

If you've never been, I can highly recommend a trip to "Biosphere 2" in Arizona which is a semi-retired monument to the whole idea, and quite worth the tour.
