Description:

Made from natural melted rocks blown into mineral fibers, Grodan stonewool (generically known as rockwool) has become the preferred choice for soilless growing worldwide. Using their exclusive Delta® Technology for improved fiber structure and layering, they create perfectly uniform products that are both inert and compliant to the highest environmental and quality standards. This provides a clean medium for growing spectacular vegetables, fruits and vibrant flowers. These growing blocks are made for direct sowing or "blocking on" of Macro and Multiblock raised plants. The blocks can then be placed on top of a slab to provide for a larger growing volume.

3" x 3" x 2.5" - 8 blocks/strip - 48 strips/case
