One inch rockwool seed starter plugs 200 count

Data updated 2026-09-13

This catalog entry features a larger pack of 200 rockwool cubes for growers who manage more intensive planting schedules. Each one-inch cube is designed to fit into standard nursery flats, providing a stable environment for germination. The mineral wool material is highly absorbent, ensuring that seeds stay moist during the critical first days of growth.

The internal structure of these plugs is designed to balance water retention with air porosity. This balance is vital for preventing the damping off of seedlings. Since the material is pH neutral after a quick soak, it offers a clean slate for nutrient management. These plugs are suitable for both traditional hydroponic setups and aeroponic cloning machines.

These listings offer a practical solution for those who need to start many plants at once. The uniform size of the cubes ensures that every seedling receives the same amount of moisture and space. Once the roots emerge from the bottom of the cube, the entire plug can be moved into a net pot filled with clay pebbles or other media.
