Rockwool planting cubes 1.5 in size
Data updated 2026-09-13
This catalog entry features 24 individual rockwool cubes measuring 1.5 inches. Rockwool is a mineral-based medium that provides an excellent balance of water retention and air porosity for developing roots. These cubes are commonly used for starting seeds or taking cuttings from established plants before moving them to a larger system.
The material is spun from molten rock into a fibrous texture that holds its shape even when saturated. This provides a stable environment for delicate new roots to take hold without the resistance found in soil. Each cube is uniform in size, ensuring consistent moisture levels across your entire tray of seedlings.
These listings are suitable for various hydroponic methods, including drip systems and deep water culture. The 1.5 inch size fits perfectly into standard net pots or can be placed directly into larger rockwool slabs. They are a clean, sterile option for growers who want to avoid the pathogens sometimes found in organic media.
