Possible new substrate

While walking around Lowe's (builder supply store) garden center I came across a product called Inviroguard Mulch. The product looks like bark, comes in a brown/grey or red color, 30lb bags, at $6.49USD. The product is made %100 from recycled paper, the company states it has no harmfull chemicals, and has weight like bark not carefresh. I'm thinking I may give it a try and thought to pass the word to others that may be lookng for something cheaper than most other substrate products. Here's the company link Inviroguard Mulch
