Prepare Plant Rafts
PREPARE PLANT RAFTS
The templates below show one of many ways to prepare 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 or quarters (shown) for easier handling and harvesting. Layout desired pattern and drill holes. Hole size depends
on what plants you intend to grow and media you will use. Consult with your sales representative for additional information
about growing plants in your aquaponic system. Hole size shown is 1-3/8".
Top diagram shows a 24" x 48" panel.
A step bit* allows for drilling
a uniform size hole through
the rigid foam board. It also
allows you to drill a tapered
hole that works better for
some media. Determine
which type of hole is needed
for your planting needs and
prepare the rafts accordingly.
Experiment with different
bits until desired results are
achieved. For net pots, do
not use a step bit.
*Step bit is not included.
Purchase locally if needed.
Photo above shows drilling
holes in the rigid foam board
using a step bit. Hole pattern
show above is staggered.

IMPORTANT:
Read the system cycling information under the Start Up
section
before
drilling plant sites in polystyrene panels. Solid panels can
be used to cover raft beds during the cycling process.
