Our Pargro line has been modified to be the driest value-priced Rockwool in the market. Pargro Quick Drain (QD) blocks are up to 14% drier than Cultilene Comfort blocks. Pargro QD slabs are up to 10% drier than our previous Neptune slabs. All Pargro QD slabs have vertical fibers, similar to the Grodan Expert Gro-Slabs. Pargro is the leader among affordable horticultural Rockwool. Since it is made right in the Grodan factory, you can be assured of a high quality product at a great price. Made from natural melted rocks blown into mineral fibers, Grodan stonewool (generically known as rockwool) has become the preferred choice for soil-less growing worldwide. Using our exclusive Delta Technology for improved fiber structure and layering, we create perfectly uniform products that are both inert and compliant to the highest environmental & quality standards. This provides a clean medium for growing spectacular vegetables, fruits and vibrant flowers.
