Grodan Improved Uni-Slab (9.5x9.5x8) w/ 4x4 Pre-Cut Hole

Grodan Improved Uni-Slabs (9.5x9.5x8) w/ 4x4 Pre-Cut Hole are designed to enhance water distribution and root development through advanced hydrophilic technology. Featuring the Advanced Wetting Agent, this slab ensures more uniform water content (WC) and electrical conductivity (EC) throughout each unit and across multiple slabs, providing growers with greater control over irrigation strategies. Its improved structure promotes fast rooting, vigorous plant growth, and better resilience, making it ideal for optimizing cannabis cultivation. With a solid base and increased substrate volume, the Grodan Improved Uni-Slab supports higher yields by enabling strong root expansion, rapid re-saturation and enhanced steerability throughout the growing cycle.
