Grodan® Stonewool Grow Chunks
Light, airy & versatile. GrowChunks are about 3/4 inch square each and can be used in pots around blocks or alone. They are easily combined with other media, such as layering with coco fiber or clay pellets. They can also be combined with soil for added aeration and increased moisture holding properties. Great for hydro systems or container gardening.
Coming November 2009.
