There was some legal wrangling going on with the originator of the Epiweb and Ray calls his product now Ecoweb. I am still used to calling it Epiweb, and Ray never took this page down either.

Whatever the name, I like it for a lot of Orchids. Cattleyas grow right into it, actually I think it works best on all Orchids with fat roots.
Moisture holding properties are not too different from Tree fern. My benches would bend if I pot on into huge clay-pots, these Eco/Epiweb baskets are nice and light. And aside from picking up some baskets here and there, I buy the large slab and cut it to size for mounting small Orchids.
