Super light and Super versatile.
Grow Chunks are a larger version (3/4" square) of the popular Grow Cubes. The larger size makes Grow Chunks hold onto moisture and nutrients longer than the Grow Cubes giving you a little more time between watering. They are great for direct planting or for use as a filling around blocks in containers. They can be easily mixed with other media for increased aeration and added moisture holding capabilities.
