Cultilene Rockwool 6" Big Block

Regular price Price: $4.10 CAD Sale

Cultilene rockwool offers superb air to water ratio, a fibre structure that holds water longer,
and less resistance for the roots to grow in the block, resulting in better roots for "fragile" crops.
It's unique fibre structure lends to faster initial rooting.
All products are uniform for guaranteed firmness.

Larger size makes it perfect as a standalone medium. Roots grown in the cube become much more efficient, letting more energy divert back to stem and bud growth.
