Rockwool starter plugs for plant propagation

These listings offer a bulk pack of 100 rockwool cubes specifically for starting new plants. The material is spun from molten rock into a fibrous texture that holds water and air in an ideal ratio. These plugs are a standard choice for growers who need a reliable medium for seeds or fresh cuttings.

The stonewool structure supports vigorous root growth by allowing young roots to penetrate the material easily. These cubes fit into standard germination trays and can be moved into larger hydroponic systems once the plants are established. They remain stable over time and do not break down or clog irrigation lines in the system.

Using this set of propagation media helps ensure a high success rate for clones and seedlings. The neutral nature of the rockwool allows for precise control over nutrient levels from the very beginning of the plant's life. It is a clean and effective way to manage the early stages of indoor or outdoor gardening.
