Grodan Rockwool Cubes feature eight interconnected cubes in a single strip, each 75 x 75 mm with a 3-inch central hole for seed or cutting insertion. Constructed from stone wool, this inert, pH-neutral medium provides balanced water retention and aeration to support root development in seedlings and clones. The sterile composition minimizes disease risk, while the uniform density ensures consistent moisture distribution. Cubes separate easily for individual use and allow root expansion without damage during transplant to larger pots or systems. Suitable for hydroponic propagation and traditional growing setups.
Grodan cubes x 8 in a length – 75 x 75 with hole (3 inch)
