James,
I have heard from others that Reptile Bark also works better than the Pine Microbark but again, very expensive at Pet Stores. Maybe, we could find a Distributor who sells it to Zoos, and buy it in bulk???
In any event, based on tom-ato's results I will fill a few 'Tainers next Season with the 3:2:1 Combo Mix using Orchid bark instead of the Pine for an "A/B" trial.
