A number of local growers, myself included, make net pots from gutter
guard (fine guage), which is normally used to keep leaves and debris out
of roof gutters. It works even better as a mount: instead of putting the
plant in the gutter guard container, mount it on the outside and fill
with a mix of your choice (I use peat and perlite). When the mix needs
renewing, simply tip it out or gently wash it out and replace. Because
the material doesn't seem to break down under even the strong UV we get
in Brisbane (Australia), you have a perpetual mount which will not
decay.

Different shapes and sizes can be made - for small ones, no support is
needed; for larger, try aluminium wire (bonsai wire, for example) to
obtain a square or cylidrical shape. Just the shot for some of the
scrambling bulbophyllums and coelogynes.

Cordially, Phil
