So very nice. I'm new to zygopetalum. Trying to repot two new zygopetalum I got two days ago. Looks like you just use bark and a little perlite as the growing media? And you grow it indoor right?
It would be nice for you go to the Introductions forum section and introduce yourself to us. From the left yellow menu choose Forums then Introductions - Break the Ice. Near the top left center is a button New Thread. People might not see you here in a thread devoted to something else.
Also, the Search feature is quite useful. You can find how other people have potted and grown Zygopetalums. Depending on what part of LA you live in they might be easier to grow, or not.

You are welcome and welcome aboard! I’d echo estacion’s sentiment to seek out what’s working for others and to investigate the needs/culture of your plants on the web at large. From there you can distill the info down to fit your particular conditions or those that you wish to create.
