Plastic orchid tube with rubber cap, used for water supply in cut orchids.
Can be pulled over the roots of Vanda, Ascocenda, Rhynchostylis and their hybrids for water supply in low humidity. The roots will soak up the water in 3-5 days, then invert the tube over another root. Do not supply all roots with the tubes at the same time. Be careful not to damage the tip of the root.
