Ross here is a question for you. I posted this question earlier today somewhere on OB so I will ask you. Have you ever mounted any orchids on bark? I plan to mount 6 windowsill Catts on Cottonwood Bark. It is really course and resembles Cork Bark. I have read folks use cedar, oak, cork, tree fern, driftwood etc... I have access to lots of cottonwood bark. What do you think?
