Has anyone used Fox Farms Up Country soil?

I have always used FFOF, but during my last visit to the greenhouse/garden store where i shop i noticed some big plain white bags of Fox Farms Up Country soil in the back of the greenhouse, that the store was using for their plants and repots. The soil is for commercial use so the bag says, i asked if it was for sale and they said it was the same price as the FFOF but the bag is double the size.

I cant find much about the soil online, just wondering if anyone else knows anything about it. i plan to cut the FFOF with it to help lower my cost. and use it outside for other random stuff.

I picked up a bag, but have only used it outside for everyday stuff, and not much there.

does anyone know anything about it? anyone used it?

good idea to cut ffof with it. i do the same and cut mine with two other types of potting mix. also add some amendments as well to improve quality and texture
