These listings feature a high-volume pack of 200 rockwool cubes, each measuring 1 inch. This size is specifically tailored for seed germination and the propagation of cuttings. The small footprint allows for a high density of plants within a single nursery tray, making efficient use of grow light space.

The cubes are made from molten rock spun into fibers, creating a medium that is both sterile and porous. This structure allows for excellent drainage while keeping the base of the plant moist. Because the material is inert, it does not affect the pH of the nutrient solution used during the early stages.

This set is a practical choice for growers who frequently start new crops from scratch. The 1 inch size is easy to transplant into larger media like clay pebbles or bigger rockwool blocks once the roots emerge. It provides a consistent environment for young plants to develop strong foundations before moving to a main system.
