Emmersed Plant growing experiment

Experimenting with Emmersed growing, I believe the plants are  Sagittaria subulata and a Cryptocorne. Substrate is a layer of gravel capped with plastic mesh then a course mixture of house plant compost with Orchid compost. Currently outside where the temperature is 20 C.

Update. The plants survived but did not put on any fresh growth, so I moved them into an aquarium in the green house and they seem to be doing OK. The substrate mix I used became pretty smelly from the decay. It seem it is recommended that some Activated charcoal is added to the mix to absorb some of the volatiles produced by the decay process.
