Grodan® Rockwool Delta Gro-Blocks™ & Big Mama

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.
You can view the product as a fancy form of container for your plant. The container (or the stone wool) holds the perfect ratio of water and air that your plant needs. The fibrous structure of the stone wool gives your plant something to anchor in. The container or the stone wool does not provide any food for your plant. You therefore use plant food in the water each time you water.
