Pack of 72 rockwool cubes (2.5 cm) with 5.1 cm mesh pots for hydroponic growing systems. Good water absorption.

1. Premium Material: Our rockwool cubes are made from premium inorganic basalt fibers and compressed into blocks using a proprietary process. They have a soft, uniform texture, good water absorption, and high air permeability, making them the best substrate material for soilless cultivation.
2. Easy to Transplant: Rockwool cubes for hydroponics keep seeds healthy long enough to establish a root system because they have high water absorption while retaining plenty of oxygen. This 1-inch square rockwool block holds its shape well without collapsing, making it easy to transplant.
3. Slotted Design: These hydroponic mesh pots with holes in the bottom promote healthy root development with even drainage. This allows roots to grow naturally, passing through the mesh and emerging on the side to form larger, healthier roots.
4. Easy to use: Cut several pieces of rockwool with scissors, soak them briefly in a nutrient solution for about 10 seconds, and adjust their EC and pH values ​​to the range required for the seeds. The optimal pH for most plant seeds is around 5.5. Then, control the humidity, light, and temperature appropriately. When the root grows more than 1 inch beyond the rockwool, it's time to transplant it into its new home. 5. Rockwool Cubes with Mesh Pots: The package includes 72 pieces of 2.5 cm rockwool cubes, 50 5.1 cm mesh cups, and 1 self-watering cotton wick cord. This kit can help you with successful hydroponic growing.
