Description
The Vivosun 1.6″ Rockwool Grow Cubes (1 Sheet, 28 Plugs) are sterile propagation starter plugs designed for seed germination, cloning, and hydroponic cultivation. Made from high-temperature processed basalt fibers, these grow cubes provide a stable, moisture-retentive rooting environment that supports fast germination and vigorous early root development.
With a highly porous structure, the cubes maintain an ideal balance of air and water retention, allowing roots to receive consistent oxygen while absorbing moisture and nutrients efficiently. Each cube includes a pre-formed planting hole for easy seed or cutting placement, and the sheet can be separated into individual cubes for transplanting into hydroponic systems, soil, or net pots. Suitable for both hobby and commercial growing applications, these rockwool cubes offer clean, uniform propagation support across a wide range of plant types.
