Repotting several orchids.

[WhiteRabbit]

I pot Paphs in fine fir bark mix (mostly bark, with some perlite); remember that Paphs generally like to remain lightly moist.

Phals and Darwinara, I'd use medium fir bark mix, and you can add whatever else you like to aid in drainage, aeration, and drying.

Using a skewer in pots can be very helpful in determining when to water, and as such can ease the anxiety over potting media and mix.
