Referring back to post #2 that Terry sent to you:

HOW TO MAKE ABG

<The ABG mix is-------- 2 parts tree fern fiber, 1 part peat moss, 2 parts cocofiber, 1 part charcoal, and 2 parts orchid bark>

The ABG I purchase has some dried sphagnum moss in the mix as well.

As mentioned - be sure all parts are organic and chemical free .........no fertilizer or pesticides.
