Will this work as an Orchid Terrarium???

[VMStearns]

I have a lovely "vase" thing in the shape of a fish. I grew up along the Columbia River and spent my summers fishing for Steelhead and Salmon so I love anything FISH.

I have never done anything with this oddly shaped vessel and am now wondering if I might use it as a terrarium for micro orchids.

I've filled the bottom with decorative glass "pebbles" topped with landscape cloth and a fitted cocoa-mat and filled it with distilled water so the mat gets some water but is not waterlogged. I can change that configuration...this is just my starting configuration.

I've also included some porous lava rock I collected on private property in the Bend Oregon area (Newberry Caldera where the Obsidian Mountain is open for exploration).

The overall interior dimensions are about 5" tall by 10" wide.

The vase sits above the entertainment center so it is pretty warm (around 80 degrees F) and sits about 10 feet from an EAST facing patio door.

Any opinions?
Any suggestions as to what would do well. Obviously I am thinking some Warm growing orchids due to the location.

Thanks in advance.
