The root zone doesn’t lie. Vertical fiber rockwool is a game changer for uniformity.

Took a quick peek under the slabs in the greenhouse today and the root development is looking incredible. That pearly white "explosion" never gets old. 🌿

I’ve been tracking the performance, and it really comes down to the fiber structure. The Air-Filled Porosity (AFP) is spot on—roots are breathing perfectly and hitting the bottom fast. What’s impressed me most is the uniformity; the vertical fiber tech seems to prevent any water channeling or dry spots, which makes dry-backs so much more predictable.

It’s always satisfying when the engineering matches the results. How are you guys managing your dry-backs this season?
