Thank you Gloria!
They used to live in the humidity trays with low-ish light, so they produced nice leaves but not much blooms. Now in the tank with bright lights I am hoping for lots of blooms .
Thank you Phal_grower.
I used egg-crate sheets 4 ft X 2 ft from Home depot cut to size for my levels.
The levels are resting on the glass vases of different height, but you could use for support anything that has same height, stable and does not rot in the high humidity conditions. Some people use cut PVC pipes from the plumbing department.
