Yes, it's very easy to convert a
megagarden or similar self contained e&f systems to
DWC.
A six site conversion
and a four site conversion
It's just a matter of building a cover plate and
center support similar to the suspended planter ebb
& flow method, only the tray portion of the system
is discarded, allowing the roots to grow out, and into
the aerated solution reservoir.
Plate dimensions
for the megagarden are 21-3/8" x 21-3/8" with a corner
radius of 1-1/4", the plate fits in the recessed area
around the perimeter of the megagardens reservoir
section.
The aerating action
Notice the longer center support tube. 2" pvc pipe
was cut to 8-3/4" long. For larger cover plates (not
sitting in recess around lip of system) the center
support should be cut to 9" long.
