Are you into the hydro-growing business? Or have you tried this type of business? If yes, this video is something that you can talk about. Featuring Murray Hallam, a hydro grower, this video informs about the different types of systems used in hydro-growing. He illustrates the nutrient film technique (NFT) system he has been using, and later walks to another type, which is the deep water culture (DWC) system. He believes this brings in more profit. In the video he explains why DWC system in aquaponics is better than NFT system, commonly used in hydrosystem.
Hallam notes that one of the problems that hydrogrowers experience with NFT system is water temperature. In this system, a thin film of water is running down the channel. On a hot day, the water temperature can rise to several degrees. As a result, you feed your plants with hot water. Plants like lettuce doesn’t want water with temperature above 22 degrees Celsius says Hallam. On the other hand, with DWC system, you have a larger mass of water. This makes the water temperature stable. Another benefit of DWC system is pH control.
Hallam is converting his farm setup from hydroponics to aquaponics. He acknowledges that it needs big capital costs to replace the system right away. He advises that it is wise to convert the system gradually. His decision to convert from NFT system to DWC system is due to the significant advantages DWC system over NFT system.
In aquaponics, you can raise both plants and fish. But the main game is raising the plants for an early return on investments. Physical labor in a DWC system will just be as simple as coming to work to check the pumps and pipes, and to harvest. How much you have to harvest and when depends on your marketing strategy. Over the week you have to harvest and plant a seedling for replacement. “Obviously, initially you have to put a lot of effort into it,” says Hallam. But once you are organized, Hallam says, physical labor will only constitute about two and a half hours per day.
