Grodan®

GRO-BLOCKS Big Mamma, 8" x 8" x 8" | Case of 18

The largest block ever produced by Grodan, the Big Mamma™ measures 8" x 8" x 8" 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 Mamma.

This block does not have a precut hole, making it suitable to hold any size smaller block on top.
