grow in these without any medium. Once lined with with coconut husk fiber
though, medium will stay in without getting washed awayallowing
many types of orchids to grow in them. One of our customers used this
method for an Oncidium ornithorhynchum and it grows and blooms beautifully
(not an orchid Id have suggested...just shows you can always learn!!!)
Theyre wonderful for vandaceous orchids and many bulbophyllumswe
even have a bromeliad growing VERY happily in one.
Each comes with a 4-wire hanger.
