These listings include two sheets of rockwool cubes specifically designed for starting seeds and clones. Each sheet contains 28 individual plugs, providing a total of 56 units for propagation. The material is chosen for its ability to hold water while maintaining high oxygen levels around the developing root systems.

The 1.5 in cubes fit easily into standard nursery trays and net pots. This grow media is inert, meaning it does not interfere with the nutrient balance provided in the water. It provides a stable base for young plants to establish themselves before being moved into a larger hydroponic system or garden.

Using these plugs helps ensure that roots have the support they need during the early stages of growth. The fibrous texture of the rockwool allows for easy root penetration and expansion. This set is a staple for gardeners who prefer a clean and reliable medium for their indoor growing projects.
