|ROOT CHAMBER; The Root Chamber is made from 90mm. PVC storm water pipe.
This type is used for all new building constructions so off cut are about.
A selection of 90mm. PVC storm water pipe and 90mm. fittings are available
at large hardware stores. Fittings include right angles, tee junctions,
end caps and others. These can be used to make the root camber suit any
room. The root camber show in Diagrams (fig.5,6,7) is made with two lengths
about 1 miter for the sides, 2 lengths about of 600mm. for the ends and
4 right angles for the corners. PVC pipe glue is used to make all joins
water tight. A
slot is cut in the top of each side providing access to change growing
medium and remove root mass. Holes instead of a slot may be used
for each plant but another way of access must be used. A drain hole
or holes are drilled in the bottom of one end of the root chamber
and a flood hole is drilled in the top of the other end. The root
chamber is mounted on an angle with drain end below then the flood
end. This is to ensure that the roots don't get water logged. Too
much of an angle will cause the Rockwell and roots to dry out at
the high end.
