Made in Denmark since 1969, horticultural stonewool is used the worldÂ over by both hydroponics and soil gardeners. Growers can start cuttings and even grow plants to maturity in this large Grodan Gro-Block or transferÂ it to a larger stonewool slab once roots have been established. Gro-Blocks can be planted directly into containers for soil gardening as well. This is a single 6" x 6" x 6" Gro-Block with a preformed hole. Grodan stonewool is known for its quality, consistency and performance.
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 Grodans 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.
