Lettuce rafts aquaponics Beaver Rafts

Please see the video at the bottom of the page and the sizes.

Beaver Plastic Lettuce Rafts (Beaver Boards) are floating raft systems made with recycled food grade resins and are used to cultivate fabulous leafy vegetables and herbs in a deep water culture. The entire board is built on certified food grade resins, not just the skin. The seal is a heating process we do to the polystyrene that is why it is so smooth.  The Lettuce Raft is ideally suited for deep water culture, floating your plants to success. Sealed Surface Technology® Lettuce Raft resists water penetration, ensures durability and longevity, and gives growers a cost-effective system. 

 What makes these lettuce rafts state of the art is the fact that they:

  • "Sealed Surface Technology" Resist water penetration.  (See image below)
  • Resist root penetration- keeping the roots intact for transplanting
  • Specialized cell shape to encourage roots to bind together with the soil into a single plug
  • Are built to last and have dependable durability and longevity
  • Offers a cost effective system
  • For indoor or outdoor use
  • These lettuce rafts will float your boat and your growth!
Start with sterilized deep water beds in a greenhouse.  Add seedling plugs to the lettuce raft. Add the lettuce rafts to the deep water circulating tanks, and let them float.  Lettuce will be ready to harvest in 5-7 weeks!
