Consistent Batch Format
Manufactured with a highly uniform fiber density, helping limit block-to-block variation and support repeatable water management across your entire commercial canopy.
The Cannabis Rock Wool Growing Block 15P (RM-15P) provides excellent rootzone water-oxygen balance for high-yield cannabis. Use it standalone or stacked on grow slabs, enabling precise crop steering and hydroponic nutrient uptake.

Manufactured with a highly uniform fiber density, helping limit block-to-block variation and support repeatable water management across your entire commercial canopy.
The optimized air-filled porosity allows for rapid, predictable dry-backs. It seamlessly supports dynamic P1, P2, and P3 irrigation phases when irrigation is managed appropriately.
Creates an ideal breathable micro-climate that supports root-zone aeration, stimulating vigorous lateral root branching and maximizing EC/pH stability.
Available with tailored basal grooves and pre-drilled hole options to match your specific benching style, effectively minimizing nutrient run-off pooling.
Brands: Multiple options available.




| Block Size (L × W × H)mm | Hole Size | Hole Layout | Base Grooves (Bottom Drainage) |
