It sure looks pretty, Ken, but I can't help thinking an orchid could attach better to a rough, porous natural surface. It also will retain a little moisture which can't help but increase humidity around the plant. Considering how fast mounted orchids dry out, that's a plus, as well.
My 'chids sure do attach nicely to the rough surface of the cork. They also attach themselves to the sides of plastic and ceramic pots, but the ones that attach to clay pots stick more strongly. eg. I usually have to break a clay pot to re-pot its inmate. The roots will let go of ceramic and plastic pots if I soak them well in water.
