Is this Pine Bark Fines?

[VitaVeggieMan]

I've been using a product from Home Depot called "Garden Pro Clay Breaker Soil Conditioner" which is a mix of aged bark fines and gypsum. It seems to be about the right consistency, though I do pick out the biggest chunks and sharp pointy pieces as I mix it with the peat-based potting mix. The other advantage is that it's about half the price of potting mix. I use about half of each in my grow media, with some extra perlite thrown in for good measure. Seems to work well in self-watering containers.

I live in Northern Virginia, so I don't know if they carry this everywhere. Here's a link to it on the HD website:
