Grodan Stonewool Gro-Blocks 8 inch
Made in Denmark since 1969, Grodan stonewool is known the world over for its quality, consistency, ease of use and performance.
The largest block ever produced by Grodan, the Big Mama, measures 8 inch x 8 inch x 8 inch and contains well over twice as much wool as the popular Hugo block. This block is big enough to grow a large plant for its entire life. When a plant outgrows its current block, gardeners can simply place it on top of the Big Mama. This block does not have a precut hole, making it suitable to hold any size smaller block on top.
