Mile High Colorado Glacial Rock Dust Reviews

I can't honestly give it more than three stars. The major problem with this rock dust is that it's clumpy, with a texture much closer to a clay than a "dust" or "flour." The description suggests that it "..does contain some water weight," and it's not wrong. It clumps together in soil, making even dispersion extremely difficult. I emailed customer service at BAS to ask about this, but never got a response. Either way, my soil works quite well with this as my only rock dust, but the effort that went into mixing it evenly was much, MUCH more than with other, drier rock dusts. I had to literally "de-clump" it between my fingers after moistening the soil. Going by the mineral analysis, this stuff has ample calcium and many trace minerals that are likely plant-available, so it's got some upsides, but I would recommend using this as part of a rock dust blend along with basic GRD and maybe basalt fines rather than using it as a stand-alone.

Havent yet seen the results because soil is cycling. Should work great!

The shipping dept. does a fantastic job. I got my GRD 1 day early. Great looking product.
