For $139 – you can feed your family healthy greens, get a pet, and teach your kids how to save the world through better ecological understanding.

Your fish tank can now double as a garden. Those little fishies just need to keep doing what they do best – swim, eat and poop – and with the proper system you can grow a bounty of produce in your very own home.

This tank can grow all the ingredients for a perfectly good salad, including tomatoes, lettuce, kale, mint, basil and wheatgrass. The kit can be purchased with seeds, but (founder) Ikard says you can easily use your own sprouted starter plants in the system. They’ll start to germinate after a day or two. The tank can also raise flowers and indoor plants if the edibles aren’t your thing.
