Apply the Sandponic farming method, which is fully controlled automatically by providing an ecosystem based on the idea of integration and mutual benefit between plants and fish through a closed cycle of irrigation and drainage, so the plants are irrigated through water laden with fish waste that contains all the elements it needs. The plant and water is purified by passing through the sandy soil to be drained purified from ammonia to the fish tank, which in excess leads to the death of fish.
