Prepare Plant Rafts
The templates below show two of many different ways to prepare the plant rafts. (There are other patterns.) Each
has its advantages. Determine the best pattern for your growing needs and prepare the 4' x 8' rigid foam boards as
needed. Rafts can be cut in half (see dashed line) for easier handling and harvesting. Layout the desired pattern and
drill the holes. Hole size depends on what plants you intend to grow and the medium that you will use. Consult with
your sales representative for additional information about growing plants in your aquaponic system.

A step bit* allows for drilling
a uniform size hole through
the rigid foam board. It also
allows you to drill a tapered
hole. Determine which type
of hole is needed for your
planting needs and prepare
the rafts accordingly.
*Step bit is not included.
Purchase locally if needed.

holes in the rigid foam board
