Introducing RaftMaster™

What is The RaftMaster™?

The RaftMaster™ is a modular framing system for deep water culture growers. Made
from durable galvanized tubing, the engineered design and precision manufacturing allow for sizing flexibility from 2 foot to 8 foot widths, to any length in 2 foot increments.
The modular design makes this an ideal frame for backyard growers to large commercial operations.

The RaftMaster™ is carefully designed to utilize only a few different components and with the step-by-step assembly manual, the frame can be quickly assembled.
Bulky wooden frames that warp, rot, and are insect-prone are now obsolete! No more wasting your time measuring, cutting, nailing, and painting!

Why use The RaftMaster™?

  • Time is Money: Why waste your time trying to build a frame out of wood?  Plus cutting out materials, trying to figure out how to put it all together, and then painting it?
    We’ve done all the hard work and produced an easy to assemble frame!
  • No bugs: Most frames are constructed from wood. Usually this lumber is
    treated with nasty chemicals to prevent rotting or is painted. Eventually the lumber becomes infested with termites, fire ants, carpenter ants, or other wood-boring pests.
  • Complete Kit: The RaftMaster™ frame comes with everything you need: Frame components, screws, bolts, and liner clips. Just add the liner and your deep water culture bed is ready!
  • Standard Sizing: The frame is designed to hold standard 2 foot x4 foot rafts (or any raft in a multiple of 2 foot sizes). The RaftMaster™ bed is slightly larger in length and width to accommodate a

    little wiggle room for the liner and raft movements.
  • Flexible Sizing: Designed to be expandable by 2 foot sections,
    the RaftMaster™ will accommodate almost any growing space.
  • Easy Assembly:; We provide a detailed step-by-step assembly manual that contains accurate and concise diagrams. There are only a few unique parts and with the simple instructions, you’ll probably just ignore the instructions once you start assembling!
  • Light Weight: The tubular design is strong, but light. Most of the smaller
    beds can be assembled and then moved into their final location.
  • Strong: Although you shouldn’t do this, we have walked along the edges of our frames and they didn’t buckle under the weight of an adult.
  • Long Lasting: The RaftMaster™ is fabricated from galvanized steel – the same type of

    material used to construct many commercial greenhouse. This will provide you with years of dependable use.
  • FREE Shipping: Complete RaftMaster™ sets are shipped for free to anywhere within the continental United States.

    • As with any galvanized product, we don’t recommend using this in areas with excessively high moisture and salt levels.
    • The liner clips are made from UV resistant ABS plastic. Depending on the amount
      of UV light they receive, they should last 3-5 years before being replaced as needed.
    • The RaftMaster™ bed is designed to be installed on a clean and level surface.
      The liner that you install will be resting directly on the surface. Therefore, the
      entire area should be completely clear of any debris that may puncture the liner.
    • A puncture-resistant liner (such as DuraSkrim, UltraSkrim, or ToughSkrim) should be used.
      Plastic films that do not contain reinforcement fiber should be avoided.
    • When filled with water, the total weight will be roughly 60 pounds per square foot.
      Please make sure your area is capable of supporting heavy weights.
    • Even though we mentioned this is strong enough that we can stand on the edge, you should not. It is not designed to support human weight, plus you would probably fall in the water!
    • These are frame only kits, Liner sold separately. Cut to size option coming soon but 6′ x 100′ rolls available now.UltraSkirm FGC

    We also sell Air Diffusers for use in raft beds. About .5 CFM (cubic feet per minute) of air is recommended for every 16 square feet of bed.

  • Just skimmed the page.. What’s the depth of the raft?

  • 12″ total. It will hold right up to the rim but 10-11 would be best. 😉

  • Paul

    What keeps the liner from sagging out through the frame? The gaps seem rather large. Do you have pictures of the system in use?

    • TCLynx

      Under the bed, the ground/floor/or whatever you place the bed on needs to support the liner on the bottom.
      On the sides, the clips securing the liner along the top edge keep the liner from falling down and gravity pulling down on the liner keeps it from bowing out on the sides, the liner needs to be secured tight enough so that it is pulling down on the sides rather than having enough slack to push OUT. It is recommended that a string reinforced or scrim liner be used so that it has enough structural strength to support the weight rather than stretching.

      I do not yet have pictures of this kind of bed in use (I will soon but it is still under construction.) I do have pictures of a similar construction method which I have been using for years
      Rail Bed Rig
      That similar construction method uses larger pipes and clamps and is not something I ever managed to make a really good kit for. This new product should work well for the on the ground raft beds though it may not be able to support an off the ground media bed without a very sturdy platform built separately.
