Recycled cellulose made in Pennsylvania ain't too shabby compared to what's currently on the shelves for a base medium in a potting mix.

The test I saw I thought showed high but I could be mistaken. I look at too many of these tests on a given day it seems like.
Why would you want low CEC unless you have a dialed in and schedule fertigation program?
Yes, peat and coco are not perfect. There's a reason the nursery and horticultural world are using peat moss though and not pit moss.
I'm all for sustainability and environmentally friendly options. I have a greater fossil fuel cost to get pitt moss to me on the West Coast than peat moss from Canada or local bogs.
As someone running a commercial nursery and greenhouse, I can't afford to pay double my cost for media or more (which was where pitt moss landed).
If you're a home grower and not having to look at numbers and live closer to the source, then maybe it's a good option.
I'd like to know a bit more about how it's made in regards to fossil fuel costs, etc.....and also if there's been any heavy metal testing done on the final product especially cadmium levels.
If you have any of these answers I'd love to learn more. Thanks!
