Orchid Potting Media, What size chunks for what orchid?

[emmajs243]

Ok ok, I know, another post by this Emma girl but I started trying to place an orchid order and found myself filled with never ending questions of what size bark for Phalaenopsis, medium, ok well what size is that? Some orchid bark isn't sold by grades but actual inch sizes. Then I followed with well what would I get for my Cattleya? The same? Smaller? What about my Cymbidium?

What I hope this thread turns into is a concise list of types of orchids and their usual media sizes at an adult age! What would be even better is if we get some preferences on any specific things you find to be best to include in Potting mixes for certain orchids and even what you would use for different seedlings!

I know there are a ton of Potting guides and information but it would be nice to be able to search one thread and get some different ideas of what medias work or don't work and what size ranges you should look for! Needless to say everyone will have their own opinions but as a beginner, I feel like when we don't have much personal experience we do base our decisions off of others preferences so what do you guys use?! Share the knowledge!
