The Encyclia are interesting plants. Mine are mostly potted in very extra dry like ways...usually with tree fern only, or those clay s/h pellets or really huge pieces of bark or most commonly, mounted. Their roots dont get thick and can be easy to over water. They take a ton of sun...only slightly less than my shomburgkia, which can go almost full sun here. Watering should be done according to how you pot it up...they need to go dry between waterings. Hopefully someone out west that grows Encyclia will be able to tell you if the spag will work okay. That can be the kiss of death down here in humid Florida.
