Grodan rockwool Grow Cubes

Grodan Grow-Cubes present an ideal solution for growers looking for an uncomplicated, user-friendly loose-fill medium. Made from consistent 1/4” stone wool cubes, these Grow-Cubes offer several benefits compared to traditional soilless mixes:

• Non-Compacting Design: They maintain their structure, creating air pockets within the container, which ensures continuous oxygen access to the roots, leading to sustained root growth and high metabolic activity.
• Optimal Moisture Balance: These cubes naturally maintain a perfect balance of 50% water and 50% air.
• Mixable for Enhanced Growth: When combined with open media like expanded clay balls, they create an optimal environment for root aeration and consistent moisture, fostering robust growth and flowering.
• Lightweight: Grodan Grow-Cubes are significantly lighter, about 1/10th the weight of a standard bag of potting soil, making handling and transportation easier.
