Hi
I have Howeara Lava Burst in my orchyterrarium
It is very easy plant for growing and blooming. My howeara bloom 2-3 times per year.
I use this substrate: Pine bark 2/4, moss 1/4, charcoal 1/4.
Light, I think, is enough compact flourecent bulbs of total power about 100-150 watts in 30-40 sm from plants.
This today photo of my howeara after 1 month of blooming
