Is the inner plastic pot solid plastic or does it have holes for air flow? If it’s the latter, then it would be good to allow for the roots to “breath” by giving them a bit more space. Phalaenopsis orchids are epiphytes, which means that they grow on tree branches, cliff faces, logs, or other structures—anywhere that isn’t directly in the dirt. This means that they prefer to have a bit of air flow around their roots. They are “aerial roots,” after all! It does mean that the roots will dry out more quickly, but this is actually preferable!
