Grodan Grow Chunk are out largest 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 don’t have to irrigate as often. Just like Grodan Grow-Cubes and Grodan Gro-Wool, Grodan Grow-Chunks can be mixed with other media and can be used with any type of irrigation system.
Grow-Chunks are incredibly versatile and can be used in many ways:
-
Use Grow-Chunks to maximize the cultivation capacity of breathable fabric pots. A 3-gallon fabric pot filled with Grow-Chunks is cable of supporting much larger plants than other soilless mixes.
-
Increase the water holding capacity of a soil-based or soilless potting mix so plants are more able to withstand summertime heat extremes.
-
Support the propagation and early vegetative development of young plants in net baskets filled with Grodan Grow-Chunks before transplanting into an active hydroponics system (g. ebb and flow, water culture, NFT).
-
When mixed with non-restrictive media (g. expanded clay balls) a very desirable blend of root aeration and homogenous moisture content can be achieved for extremely vigorous growth and bloom.
-
Lightweight — approximately 1/10 of the weight of a bag of potting soil.
