Grodan Delta Big Mama Block 8" x 8" x 8"

Gro-Blocks„¢ are similar to a plant container. Need a 3 in pot? Then choose a 3 in Gro-Block„¢. Small plants can be fully grown in our larger Gro-Blocks„¢. Holes are perfect size for any 1.5 in starter plug. Come in packs labeled with instructions. Big Mama is Grodan's largest block ever produced! Big enough to grow a large plant for its entire life. More than twice the amount of wool as our Hugo Block.
