"cylinder pots" or "deep pots" are designed to allow orchids with deeper root systems to grow comfortably.  The taller height of these pots provides ample space for the roots to grow downward.  Deep pots help accommodate orchids that have extensive or long roots, allowing them to establish a healthy root system.

"takasa yori hiroinohachi" (高さより広い針).  This term emphasizes the height being greater than the width of the pot, which is suitable for accommodating orchids with deep root structures.
