Grodan 4x 4x2.5" 6.5 Block Pro, Improved, case of 216 (36 strips)

Grodan Rockwool is consistent, sterile, and provides a perfect ratio of media to aeration. As a result, commercial farms yield more per square foot and with less variation in harvest weight.

New Grodan Improved! Improved product at current pricing. New density + new hydrophilic technology = better water distribution and root development. The uniform distribution of water and nutrients throughout the block allows for more efficient use of the entire substrate volume Full saturation of the blocks with no dry spots and improved EC control with less water is achieved in the rootzone due to the uniform, optimized wool resulting in a sustainable water and nutrient use. Improved “re-wettability” able to more easily increase water concentration in the substrate.

These are 4" x 4" x 2.5" 6.5 BLOCKS that come 36 strips of 6 per case (216 cubes) unwrapped.
