Description
The 1.6" Rockwool Grow Cubes (4 Sheets of 112 Plugs) are professional-grade propagation media designed for hydroponic systems, seed starting, cloning, and plant cuttings. Made from high-temperature melted basalt fibers, these rockwool cubes provide a sterile, structured environment that supports rapid and healthy root development.
The fibrous composition offers a balanced air-to-water ratio, allowing roots to access both oxygen and moisture efficiently. With high porosity and strong water retention, the cubes maintain consistent hydration while still preventing waterlogging. Each plug includes a pre-formed planting hole for easy seed or cutting placement, making propagation simple and uniform. Their sterile, soil-free design reduces the risk of pests and disease, while their modular structure allows easy transplanting into larger systems such as net pots, soil beds, or hydroponic setups once roots are established.
