Large Floating Rafts for Hydroponic and Aquaponic applications

Polystyrene foam rafts are a highly economical way to grow small leafy green vegetables and herbs. Floating rafts are popular because they produce an extremely high volume of food when the flow of water and aeration is right in the system. The Aqua Gardening floating rafts are produced for commercial horticulture use, in China. The polystyrene foam is inert, and quality and chemical checked. 

Foam rafts are commonly used to hold plants on top of a nutrient and oxygen rich water reservoir or tank. The raft can sit right on top of the water (floating), or it can be constructed a short distance above the water - as long as the plants they are supporting still have their roots in the water. Using this method you can grow plants faster and more cheaply than a regular media grow bed with clay pebbles. There is also the bonus of using an external filtration system to clean the water, rather than using the growing media in the case of Aquaponics.


Size of floating foam rafts

  • Dimensions: 120 cm (length) x 60 cm (width) x 4 cm (depth)
  • Made from Polysterene
  • 72 pre-drilled holes (50mm diameter) with a bevelled edge
  • Can be trimmed with sharp knife to suit smaller grow beds
  • Holes are a great fit for herb net pots and lettuce net pot sizes even considering the 50mm diameter - both types of net pots are used for aquaponics and hydroponics and they fit well.


Foam rafts for Deep Water Culture

DWC foam rafts are commonly used to hold plants above nutrient and oxygen rich water. These rafts are a suitable thickness of 40mm to prevent snapping, and so that they float while fully laden with lettuce or herbs. If you want to grow large aquaponic or hydroponic plants and trees in these rafts, a brick or inert block should be placed under the raft to support it.

The floating foam raft has 72 (50mm diameter) holes and measures 120 x 60 cm but can easily be trimmed with a sharp knife to suit other systems.
