Meet AquaSprouts Garden: a cool system that turns any 10-gallon aquarium into a self-sustaining ecosystem, allowing you to grow your own veggies and herbs all-year-around. As the fish grow and produce waste, your plants will use it to grow. You get a grow-bed that provides you with enough space for your favorite plants.
The AquaSprouts garden relies on clay pebbles to support your plants. It has a pump that can be turned on by a timer every hour to bring water from the aquarium to the grow-bed. Like what you see? You can get yours for under $170.
