Deep Water Culture Raft Boards

How the Raft Boards work:

In deep water culture (DWC), nutrient-rich water is circulated at a depth of about 8 inches while rafts (usually polystyrene) float on top. In Deep Water Culture Raft Boards, plants grow in various grow plugs, rockwool or growgrips that fit into the raft board. The plant roots hang down in the nutrient-rich, oxygenated water, 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 DWC systems, rafts can be added to extend the function of media bed aquaponic systems.

Product Details

The Beaver raft boards are made from food grade polystyrene, and designed specifically for leafy green crop production.

These 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. Save 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.
