[aroid-l] Growing wall question

From: RAYMOMATTLA at cs.com on 2003.12.19 at 03:10:07(10946) I am getting ready to extend my greenhouse and want to add growing walls on the sides. I have installed these in my current greenhouse and they are filled with long fiber spaghnum (I ended up using about 8 bales of the stuff which was kind of expensive at 50 bucks a bale. The walls in the extension will be both longer and taller so I am scared to even think about how much I may spend on that. Is there a cheaper yet reliable substitute I can use for the new walls? I know several people use coco-fiber. Is this less expensive than Spaghnum and would it quickly degrade? I have thought about buying large tree fern plaques in bulk and gluing them to the walls, everntually the plants will cover the seams, but is this a good idea? I dont really like the idea of using tree fern products to begin with! Any ideas on what i should use or should I bite the bullet and stick with spaghnum? Thanks, Michael Mattlage
