bump.....i could use this info as well.
I'm trying to start a viv with high light orchids in the very top (brassavola and slc's) and low light in the bottom (jewel orchids).
What should I make the soil structure out of.
At first I was thinking of 3" hydroton, with a screen, and then 4" shagnum....but now I'm thinking it should have an epi-web base of about 2".
Any help is always appreciated when starting a new project
