What our customers say:

Cultivating close to a half million plants per year in the Adelanto, CA high desert is not easy. We researched, ran extensive trials, and ultimately selected RedRock for both their stone wool blocks and slabs. Our plants consistently experience the most vigorous vegetative growth and heavy flowering yields we have seen.

What our customers say:

At our scale we need commercially viable products that allow us to do more with less. Stone wool products should offer uniformity, consistent dry-backs, and allow us to steer plant growth. Since running RedRock we have seen all these variables in our greenhouses
