In addition to soil, the greenhouse grows produce through aquaponics, which combines aquaculture (raising fish) and hydroponics (soil-less gardening). Through the use of a submersible pump, water circulates nutrients created by the fish to the grow beds to nourish the plants. https://t.co/SaaDdOs3qh — PolitiTweet.org
