What Do DFHS & CEA Stand For?

The Deep Flow Hydroponic System (DFHS)

Cedar Greens, by Cedarman S.A.L., are vegetables growing in floating systems: a viable alternative to soil production. By focusing on crops with short roots, the floating system offers the opportunity to grow continuously throughout the year.

The system used at Cedarman is the Deep Flow Hydroponic System (DFHS) which allows us to produce leafy vegetables with the roots completely submerged in water. We apply the nutrients before submerging the transplants, which are held upright in Styrofoam boards. Because the plant roots are submerged they’re able to feed on the nutrients in the water during their growth stages until harvest.

The Controlled Environment Agriculture (CEA)

Cedarman is one of the first companies in Lebanon to apply the Controlled Environment Agriculture (CEA) process by which it grows plants inside a greenhouse. The controlled environment allows us to maintain the proper light, carbon dioxide, temperature, humidity, water, pH levels, and nutrients to produce crops year-round.

In many cases, hydroponic growing systems are used for controlled environment agriculture to ensure that the plants receive optimal nutrients and water needed to produce an ample crop.

The entire process of controlled environment agriculture focuses on making the most of space, labor, water, energy, nutrients, and capital to operate while still producing a bountiful harvest.
