Hello, I was wondering if you could mount orchids on sea shells. I
have seen some amazing cattleyas grown on big shells so I assume its
pretty safe. I have access to an unlimited number of giant clams
shells (Tridacna sp) from a clam farm. I have read that some orchids
benefit from some calcium supplimentation from time to time, perhaps
growing them on a calcium carbonte based material may help.

Thanks
