In addition to the use of soil, the greenhouse grows produce through aquaponics, which combines aquaculture (raising fish) & hydroponics (soil-less gardening.) By using a submersible pump, water circulates nutrients created by the fish to grow beds to nourish the plants. https://t.co/XIGivyKNqR — PolitiTweet.org
