Made in Denmark since 1969, Grodan stonewool Starter Plugs have excellent capacity for absorbing nutrient solutions while retaining plenty of oxygen for rapid plant growth.
Pro-tip: These fit perfectly in the Grodan Gro-Smart tray. The big advantage of using the Gro-Smart tray is that it elevates the plugs above the waterline and ensures good airflow and drainage.
