The Grodan 150 Rockwool Cube Tray is a trusted hydroponic substrate widely used in professional horticulture for large-scale seed germination and plant propagation. Affordable, sterile, and reusable, rockwool delivers consistent and reliable results.

Its mineral fiber structure provides excellent root oxygenation, encouraging fast, uniform and vigorous root development. Rockwool also offers a high water and nutrient retention capacity, ensuring steady moisture without root suffocation.

The cubes fit seamlessly together, greatly reducing transplant shock when moving plants to soil, coco, or hydroponic systems. In addition, rockwool features anti-rot properties, protecting young plants during early growth stages.

Handling precautions: when dry, rockwool may cause mechanical irritation to skin and respiratory passages. Gloves and a mask are recommended. Once moistened, it becomes completely safe to handle.

This tray contains 150 small cubes (approx. 2 × 2 cm) mounted on a breakable plastic tray, making it ideal for intensive propagation, nurseries, and commercial growing operations.
