6 x 6 x 6 Cultilene Rockwool Blocks

Optimized Roots. Maximum Growth. Total Comfort.

Take your propagation game to the next level with Cultilene 6x6x6 Blocks, engineered for consistent rooting, ultimate hydration, and stress-free early growth. These aren’t just blocks—they’re precision tools that give every seed and cutting the environment it needs to flourish from the ground up.

Designed for Roots That Thrive 🌱

The Plant Comfort fibre structure provides a lower resistance pathway for roots, so young plants can expand effortlessly without losing firmness or support. The optimized air-to-water ratio delivers ideal moisture and oxygen balance, ensuring roots develop strong, healthy, and resilient from day one.

With even distribution of water and EC, these blocks guarantee consistent hydration while preventing over-saturation. Thanks to Optiplus technology, excess water drains effortlessly from the block’s underside—keeping roots healthy and eliminating stress from waterlogging.
