Odontocidium Tiger Crow 'Golden Girl' - Looks pretty sickly!

[King_of_orchid_growing:)]

Here's the trick...

It's all about high humidity. The higher the better. Shoot for 100% if you can.

Consistently high humidity is what's going to make the plant want to try to push out roots.

Backbulbs are referring to the much older pseudobulbs.

Backbulbs are pseudobulbs.

Pseudobulbs are not necessarilly backbulbs. In order to call a pseudobulb a backbulb, it depends on it's relative age to the newer pseudobulbs.

In horticulture, the newer shoots are usually called lead growths.

The wood the plant is growing in is technically not mulch. Mulch is much finer.

These are wood chips. Many orchids are grown in wood chips to simulate how they grow on trees in the wild.

It isn't wise to grow a plant that naturally grows on trees in potting soil. This is a big no-no. The roots will suffocate (because there's not enough air going through the soil for roots that are normally adapted to being in the air), or get infected by bacteria or fungus that it is not accustomed to growing with symbiotically (all plants have symbiotic relationships with certain bacteria or fungi to one degree or another) and die.

Rocks are a different matter entirely.
