![]() We utilize our Growasis Ground level raft systems for the main production troughs along with our waist high elevated troughs for convenient and “back friendly” transplanting and production. Seedlings in the nursery are started in compost friendly plugs that are designed to fit perfectly in the raft boards. Our Growasis Modular Raft Systems include fully constructed metal framed troughs, liner, aeration, insulation paneling and Beaver Plastics 28 hole food grade raft boards. Roots take up water, oxygen and nutrients below the raft while the plants grow above getting the greatest benefit of sunlight, proper spacing and airflow. DWC has been proven for over 30 years in research and production farms as the most reliable and consistent way to grow a wide variety of crops at a commercial scale. The primary method for plant production in our farm designs is floating raft or deep water culture (DWC). The Aquaponic Source is not responsible for actual production levels, yields, product quality, financial performance, and other business and production factors related to the farm. ![]() Results will vary in different climates and environments. These estimates are for planning purposes only. Building electrical and heating systems not included. ***Energy required for all water and air pumps required to operate the farm. **Based on Tilapia in a two tank rotation stocked at a maximum adult density of. Estimates assume an average 2 week seed to harvest time. *The nursery and microgreen system allows space for approximately 8 additional microgreen flats. Assumes 3 plants per media bed with an average seasonal yield of 45 lbs per plant. Tomatoes are shown for the sake of estimates. ³ Media beds can produce a wide variety of crops. Specific planting densities can vary by species. A realistic 10% loss rate has been factored in. ² Farms ship with 2×4′ Beaver Lettuce Rafts with 28 pre-drilled holes which equals 3.5 plants per sq ft. Culture times can vary significantly depending on a variety of factors such as: available light, artificial light, water quality, quality of seedlings, environmental controls, management of plant rotations, pests and other factors. ¹ Culture time represents the time from when the seedling is transplanted into the DWC trough to the time of harvest (not nursery time).
