I buy my coco straight from the distributor my price is verry low. I just thought if promix had a coco/perlite mix I could swing a deal on large volume. Turns out a 2 minute search could have negated my asking the question. I have a hard time mixing soils or washing coco for the volume of plants I run. It's tough to hold that much product on hand. I run a fairly large operation. Buying products to simplify the operation is a must.
