Trying to find specific Cymbidium Potting Mixture

[DJReptile]

I'm trying to find a specific potting mix that used to be commonly available in the SF Bay Area, where I live. Unfortunately I don't remember the name.

It was a Canadian manufacturer. Cymbidium mix. Made with fir bark, peat, sand, and sphagnum. No perlite, clay, or lava rock.

I used it for living terrariums. It was fantastic for my orchids, and other tropical plants I used. Additionally, without the perlite, etc. is was much safer for my animals.

Anyone know what it might be and where I could get it, or barring that where I can find a similar mix?
