Adam,

I've been growing aquatic aroids in plastic mesh pots set
into a pond for many years now. The pond is inside my
heated greenhouse (in the SF Bay Area) and the water
is further heated by a immersion/ aquarium heater and
constantly circulated with a submersible pump with the
return to the pond flowing over a small waterfall.

As you posited: water/ O2 circulation inside mesh pots
does appear better compared with using conventional
nursery pots for this application. I offer this assessment
based upon faster growth rates and reduced die-back
of new growth (i.e. sometimes a new shoot will rot out)
in my given conditions.

The media mix I use in my mesh pots:
4 - washed Monterey sand (#2/12 screen)
2- pumice
