Grodan® Macroplugs™

Macroplugs™ from Grodan® are tailored for starting seeds and rooting cuttings prior to transplanting, fitting perfectly into the hole of the Gro-Block™. These round, 1.5-inch (46 mm) plugs feature a slit that allows easy insertion of a plant cutting.

For best results, always insert Macroplugs into a tray with individual cells (such as the Grodan Gro-Smart Tray Insert) to ensure the plug stays closed around the stem of your cutting.

Grodan stone wool products are renowned for their consistency and reliability, ensuring uniform and predictable propagation with high success rates. Featuring uniform density, firmness, and fibrous structure, they facilitate both manual and mechanical processing. This uniformity also enables balanced water and nutrient distribution, fostering optimal rooting and initial crop development.
