2 Optimal use of substrate volume 4 Fast root penetration, more growing power 5 Sustainable use of water and nutrients Grodan Grocube is a porous stone wool substrate for container and bedding cultivation based on our patented Next Generation substrate technology. The cubes retain their structure even after several years' use. Thanks to its unique hydrophilic fibre structure, Grocube absorbs water easily and ensures better and faster resaturation. Easy irrigation via tricklers keeps the air/water ratio optimal in every season. Application Grodan Grocube is ideal for container- and bed-grown plants such as anthuriums, orchids and hydrangeas. This loose substrate delivers an optimum air/water ratio, resulting in faster root penetration and strong, vigorous plants. Product features - Stone wool cubes, 1x1x1 or 2x2x2 cm - Suitable for multi-year use - Unique hydrophilic fibre structure for easy water absorption - Perfect distribution of water and nutrients - High resaturation capacity Passionate about Precision Growing

Porous, dry substrate Grodan Grocube has an open, porous structure. Nutrients are not bound and are easily absorbed easily. This simplifies irrigation and makes Grodan Grocube ideal for growing crops such as anthuriums, orchids and hydrangeas. Optimal use of substrate volume The hydrophilic Next Generation fibres used in the Grodan Grocube distribute water and nutrients uniformly throughout the whole substrate volume. So roots at the top of the substrate do not lose out. The water content (WC) is easy to replenish even after long periods with lower WC levels. The cubes have a high buffer capacity...
