Deep Water Culture Raft Boards
How the Deep Water Culture Raft Boards work:
In a deep water culture (DWC) method, also known as the raft method or floating system. The Beaver raft boards are made from food grade polystyrene, and designed specifically for leaf green crop production. In this style of growing, the nutrient-rich water is circulated through long canals at a depth of about 8 inches while rafts (usually polystyrene) float on top. Plants grown in various grow plugs, rockwool or growgrips fit into the raft board. The plant roots hang down in the nutrient-rich, oxygenated water, where they absorb large amounts of oxygen and nutrients which contribute to rapid growth conditions.
This method is the most common for large commercial aquaponics growing leafy green crops such as lettuce, kale, chard, mustard, collards, basil, mint and most herbs. While most aquaponic farms employee deep water culture raft based systems, rafts can also be added to extend the function of media bed aquaponic systems.
These deep water culture raft boards are 2’x4′ in size and have 28 holes per board which results in a fully planted density of 3.5 plants per sq ft. The boards are excellent for all leafy greens and lettuce production.
Your seedlings when grown in 1″ plugs fit directly into the 1″ tapered hole without falling through. No need for additional net pots with media and all of the time and mess of cutting holes into Dow insulation blue board.
We’ve been growing successfully on these boards at our aquaponics farm for years and they are simply fantastic! These will work great in any hobby scale or commercial scale system.
If you are looking for plugs that fit perfectly into these rafts, we recommend our 128-plug grow trays.
