Grodan Grow Chunks are the larger size alternative to Grodan Grow Cubes. The increased volume of Grow Chunks means they can hold onto moisture and nutrients longer than Grow Cubes so that you dont have to irrigate as often. Can be used alone or mixed with other media and can be used with any type of irrigation system. 2 cu.
