Nina you're awesome, thanks ever so much
The 'habitat', yes - neither a table nor outdoors - it's a custom build vivarium of sorts I've been working on for the last few weeks.
I'm aware of general thinking about these though I have an Indian Star.
I don't believe there is any other way of maintaining the humidity required.
My custom build gives good floor space - and I have been working on a system of automated, configurable venting (fan assisted) so that I can try to best manage the heat / humidity / air and the challenges these three can bring.
I want good air quality, but also to be maintaining humidity and temp.
Ideally I want the humidity to increase a little at 'night time' also, as might be expected in the natural environment....
I want the habitat to look as organic / natural as possible (though of course will inevitably end up using plants that are from completely different parts of the world - though you get my meaning).
I have sculpted 'walls' (made from aquarium grade expanding foam, silicon, coir, bark etc.) and incorporated some mesh pots / portions of pots into the 'walls' so they no longer look like pots, but natural formations. Pockets really...
So - quite a few of the plants I have will be going into the 'walls', some growing up, some trailing.
Have some for the ground also - my plan being much like you suggest for these.
Expecting plant casualties
Am aware of the dangers of shop bought plants (insecticide etc), though thanks - that's how I ended up with the Pilea and Kangaroo Paw actually - bought them on the off chance they'd be safe purely because they'd be organically grown.
Thanks again Nina, can't imagine how anybody could possibly have been more helpful!!
