I just scored a 27 lbs (compressed) bale of Coco coir on ebay for $22 (+19 shipping), this is nearly 5 cubic feet when puffed up! I hate expanding the little bricks, I'd rather puff up a huge amount and not have to mess with it again for along time, this should do me for all of the 2008 gardening season and more even. If you're interested check Ebay for coir and look for the seller mountaingirl she's the one selling the bales. look at this mother next to a common coir brick:
This ain't an ad for the seller, I haven't even got my order yet i'm just so stoked about getting a whole compressed bale since I've only ever seen the little bricks for sale.
