Rockwool Grodan Big Mama Block 8 in x 8 in x 8 in No Hole

Gordan Big Mama is the largest block ever produced by Grodan. It is 8in square and contains over twice the amount of wool as the popular Hugo block. This block is big enough to grow a large plant for its entire life!

When your plant outgrows its current block, just place it on top of Big Mama. Big Mama is solid wool and does not have a pre-cut hole thus making it suitable to any size smaller block on top (even a Hugo).
