ha ha! I actually had a pretty good orange apron help me find the right adapter for my sink & R/O last night I even commended him cos it's not often someone at home depot gives a _ _ _ _!
Wal mart has those square cork tiles in the dry erase board section. I looked at them but I still have a few pieces of natural cork left so I didn't get them but I've even heard of people gluing these to the back of their aquarium and attaching epiphytic aquatic plants like anubias and java fern on them. Have not tried it yet myself though but that says alot for their durability!
I was talking to a girl at the orchid shop who was not doing well with her mounted Brassavola nodosa due to the difficulty of keeping the mounted plants wet enough. The LFS will help but I grow mine in climate controlled enclosures with a fog making a humidity of 85-100% day and night I think she was just growing hers by some other plants. Even with watering it every day she can't get it to flower.
After mounting your plant it let it soak submerged in water for a good 30 min. from then on mist it heavily it morning and night (more if you think of it) and then soak it for a few minutes every week. It is good habit to always mist with a weak fertilizer spray (about 1/4 to 1/2 strength orchid fertilizer in R/O water) and do the weekly soak or flush with pure water to remove any mineral salt buildup (which should be very minimal anyway when using low dose fertilizer and R/O water).
If your plants don't seem to do well on the driftwood you can switch to something called a Hydro Log which is like green florist foam wrapped in LFS moss. this holds a lot of water and takes a good long time to dry out (in my terrariums anyway) you can order them from
www.orchidweb.com many people preffer these to traditional cork panels because of their enormous water retention and that roots can really "dig in" to the soft green foam. But you must remeber these are heavy because they are full of water, whatever you hang it on should be very secure!
I agree Orchids look awesome grown on mounts but it takes a lot more diligence, I've fried a few myself when I first tried them mounted.
Ah, one more thought, is it possible you can set the driftwood so that part of it is touching water (like a pebble filled humidity tray-set the log on a tray full of wet pebbles)? The wood will gradually absorb the water and make it available (in minute amounts) to the roots and possibly raise the humidity in the immediate vicinity of the mounted plant as well It would help keep the LFS wet longer too. just don't let the plants roots sit in the water (of course).
