Best Potting Media for North East United States

[Amichab]

Hello, I know this has probably been asked before but I cannot find it on the forum.

I am overwhelmed by the information out there about what media to use for my different orchids. I live in Washington DC, so subtropical with hot and humid summers and cold winters. With the heater on, my winters are very dry.

I plan to put most of the 'chids out for the summer.

A few are going to be repotted in early spring. I really need help picking the right media for them for my climate.

- generic hybrid Phal (will go outside in summer)
- Sharry Baby (outside)
- Brassia (outside)
- 2 mottled paphs (will NOT go outside)
- Miltoniopsis (will NOT go outside - heat is too much but it will love the humidity)

Thank you for any information you can share!
