Forgot to add that I did get Repti-Bark ordered yesterday from Pet Mountain. Twenty 4-quart bags w/ a 10% off promo and free shipping. Hopefully, this size will be just right for the 5-1-1 mix.
The orchid bark from Amazon was money down the drain - huge chunks and a lot of large stones in every bag! (24 in just one bag.)

My local nursery - closing down for the season - had a 2 cu. ft. bag of Hoffman's horticultural size pearlite and they sold it to me at a bargain price. Nice big pieces.

I'll be ready for Spring re-potting. Seems like an eternity away .....
