Wooden plaque medium???

[jason woodrue]

Hi all,

this seems like the right place to post this question.

I know that orchids like cedar and (though i havent used it yet) cypress, grapewood, and salt-free drift wood.

anyone ever use oak? cypress? other exotic hardwoods: purple heart, bloodwood, bubinga?
general hardwoods: walnut, cherry, ash, maple?

I know some woods have oils or other secretions that make growing on them a bad idea?

anyones thoughts, experience, or other info regarding this matter would be greatly appreciated.

thanks
