Delta 10 - Improved 4x4x4" w/ Hole - strip of 6 - PRO / unwrapped

Available for purchase in increments of 24 strips (case qty) only

PRO simply means they do not come wrapped in the clear plastic outer wrap with a retail sticker and UPC code. The product itself is exactly the same, but costs less.

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.
