This is how I converted an old aquarium to be a house for some orchids.
The dimension of the cabinet is 140×55×70 cm. Rather deep but that depends upon that the aquarium is place on side with original opening outwards.
This is what it looked like from the beginning.
First of all I cut the Epi-Web material for the back
I glued it together with silicone as it wasn't long enough.
I prepared my thought of watering system with plastic stripes so I can attach the hose that will spray water into the Epi-Web. I also attached a mangrove root.
On the bottom there is a plastic material used for outdoor floor building. That is layed on small plastic cubes to get some space for water.
4 pce. pc fans handles the air movement.
To stop that to much of the pine and other small particels get into the water a fiber cloth is put on the false floor.
The cloth let water through but not other stuff I hope.
On top of the cloth I put pine. Mostly because I think it looks good.
As lighting source there are 4 36w flourosent tubes. Not a great deal of light but I hope it to be enough. All is controlled by timers. 2 timers for the 2 watering systems. 2 timers for the fans and one timer for the lights.
As for now the following is in the vivarium.
Drosera Capensis - This is not an orchid but it fights the flies that seem to like the environment. It is a meat eating spices. Better then the fly paper I had before to catch them
Vittaria Stipitata - This is a fern, looks like a shoe string.
