GROW CHUNKS™ are quite similar to the GROW-CUBES™. The larger size allows GROW CHUNKS™ to hold onto moisture and nutrients longer than the GROW-CUBES™ giving you a little more time between watering. Like our other loose media, GROW CHUNKS™ can be mixed with other media and used in any system.
- Fill a plant container with GROW CHUNKS™, or place a GRO-BLOCK™ (after removing plastic) in the middle, and surround it with the GROW CHUNKS™.
- Fill a net basket with GROW CHUNKS™ and use them in an Ebb & Flood system.
- Mix it with outdoor garden soil to aerate the soil and help retain moisture throughout the heat of the summer.
