We use only quality materials, and have made it easy to set up, operate and maintain, and it comes complete with an operating manual. FlowGrow Hydroponics (Pty) is a South African company situated in Crestholme (between Durban and Pietermaritzburg) in the province of KwaZulu-Natal,South Africa. We operate from a smallholding, and are commercial growers of a range of salad and vegetable produce. For many years we have been assisting growers to set up conventional ground lay commercial systems. Over this time we have fine tuned the systems based on our own experiences and now manufacture a number of components which were previously not available pre-assembled. After several years of careful research, our tray product, the first 'off the shelf' gravel flow system, was ready for the home market.
