VIVOSUN 1.6-inch Rockwool Cubes — 8 Sheets (224 Plugs) for Hydroponics Seed Starting & Cloning

VIVOSUN 1.6 inch Rockwool Cubes for Hydroponics and Plant Propagation

These rockwool cubes are crafted from a blend of natural minerals including basalt, coke, limestone, and a trace of iron slag. The materials are melted at high heat and spun into fine fibers, then compressed into durable blocks designed to support a healthy, breathable root zone. The result is a light, fluffy plug that holds shape while remaining easy to handle in busy propagation spaces.

Why growers choose these cubes

• High porosity of about 95 percent delivers ample oxygen to developing roots, supporting vigorous growth and steady establishment.
• Sterile inorganic composition resists fungal contamination while retaining water to keep roots hydrated between checks.
• Light and fluffy texture makes it simple to cut to any size and to observe root development through the sheet.
• Versatile for multiple setups including hydroponics, propagation, cloning, cuttings, and seed starting, with a straightforward workflow.

Practical use tips

• Each cube has a dedicated opening for seeds or cuttings and can be transferred to other media as roots mature.
• With 8 sheets of 28 cubes each, you get 224 plugs in total for a flexible propagation toolkit.
• Observe moisture and root activity easily on a single sheet before transplanting to the next medium.

Whether you are starting seeds or cloning cuttings, these VIVOSUN rockwool plugs offer a simple, organized approach. The sterile composition helps maintain a clean propagation environment while the moisture retaining properties support steady hydration and nutrient access. Use these plugs to streamline your propagation workflow, and watch for root development as a natural indicator of progress.
