| We have a grower in my area that has all his plants (in multiple genera) growing in clear plastic cups - I can see where it is quite the economical solution. As the plants mature they will most likely need repotting into something a little larger. Air roots are part of what makes phals - phals. The oldest plant I have probably has the most. Of course in the wild phals grow on trees - and they are always sending out new roots to find more bark to grab onto and to increase their surface area for soaking up nutrients as the rain drains along the trunk/branches of the trees. Whether or not your plant should be repotted will have little to do with the number of air roots - more to do with the condition of the media the other roots are in and the condition of those roots. Many of us who have been growing phals for awhile have our favorite media that we use and we automatically repot soon after acquiring in order to inspect the roots and aclimate the plant to our culture habits. In the case of a newbie growing orchids the chances are you are OK as is for some time. If you have any further questions you migth include a picture and also inspect the media and roots.
