Our Clients Said...

For years, our farms relied on Grodan, but then we found GreenGrowMaster Upuper. Their rockwool matches the quality we're used to, but at a more competitive price. Plus, their customer service outshines Grodan's by miles!

David Wong, Farm Owner, OKC

I'm thoroughly impressed with their products. Moving from coconut coir to rockwool was seamless, thanks to their team's invaluable guidance. Now, I'm seeing better yields at a reduced cost.

James Pierce, Grower, NM

I had my reservations initially, but after running some AB tests on smaller batches, it's clear that GreenGrowMaster Upuper rockwool is top-notch, ensuring consistent high yields crucial for our automated farm. A big shoutout to Rio for guiding our team through the transition.
