Description
The Grodan Big Mama Propagation Cube (200 x 200 x 200MM) is one of the largest rockwool blocks in the Grodan range, designed for growers who need maximum root volume, stability, and uniform moisture control. The no-hole design allows complete flexibility-ideal for transplanting vigorous, well-rooted propagules from smaller Grodan blocks such as 3" Gro-Blocks or starter plugs.
Engineered for precision irrigation, scalability, and high-yield performance, Big Mama cubes support strong root expansion and consistent growth throughout veg and bloom. They are best suited for drip-fed and top-watered systems, though compatible with ebb-and-flow when supplemented with top feeding.
Grodan’s world-leading stone wool technology ensures exceptional water-holding capacity, balanced air porosity, and consistent EC distribution-giving growers the accuracy required for medical, commercial, and high-performance horticulture.
