Notes from Aqua Gardening

  • For growing larger plants or trees, support the raft with a brick or inert block to prevent it from snapping.
  • Maintain proper water quality and nutrient levels to achieve the best results and ensure the health of your plants.
  • Always handle the DWC Foam Floating Raft with care when trimming to avoid injury and maintain the durability of the product.


What are the benefits of using DWC Foam Floating Rafts in hydroponic and aquaponic systems?

DWC Foam Floating Rafts provide an efficient and economical method for growing small leafy green vegetables and herbs. They enable faster plant growth and lower costs compared to regular media grow beds with clay pebbles. Additionally, they can work in conjunction with an external filtration system, which can help ensure clean water for the plants.

What size are the floating foam rafts and what material are they made from?

The floating foam raft measures 120 cm in length, 60 cm in width, and 4 cm in depth. They are made from polystyrene foam and are quality and chemical checked for commercial horticulture use.

How many holes are there on the floating foam raft and what is their diameter?

The floating foam raft has 72 pre-drilled holes with a diameter of 50mm each. These holes have beveled edges designed to accommodate herb and lettuce net pots.

Can the foam rafts be trimmed to fit smaller grow beds?

Are the floating rafts suitable for supporting larger aquaponic or hydroponic plants and trees?

While the 40mm thickness of the raft is designed to prevent snapping and maintain flotation when laden with lettuce or herbs, larger plants and trees may require additional support. In these cases, placing a brick or inert block beneath the raft can provide the necessary support for larger plants.
