Rapid Drainage & Aeration
Vertical fibers facilitate fast water displacement to support root-zone aeration.
Grofine RSP 100 rock wool growing slabs are engineered for long-cycle, deep-rooting crops like sweet peppers. The 100mm vertical fiber structure supports drainage management and precise crop steering.

Vertical fibers facilitate fast water displacement to support root-zone aeration.
The 100mm thickness creates a drier surface while sustaining a secure water buffer below.
High responsiveness allows for precise dry-backs and optimal vegetative or generative control.
Robust vertical matrix supports structural stability, supporting heavy canopies through extended growing seasons.
Brands: Multiple options available.
