Product Properties
1. Porous: with a large number of microporous and mesoporous, high porosity.
2. Good air permeability: it can effectively promote the respiration and growth of plant roots.
3. Strong water absorption: it can absorb and keep water, providing sufficient water for plants.
4. Light weight: low density, light weight, easy to carry and use.
5. Good chemical stability: It is not easy to react with other substances and is resistant to acid and alkali corrosion.
6. Environmentally friendly and non-toxic: natural materials, harmless to the environment and human body.
Product Features
1.Porosity: The volcanic rock has a high porosity structure. This allows for excellent water retention and air permeability, which are crucial factors in soilless cultivation. It can effectively store water and nutrients, and at the same time, ensure that the roots of plants have sufficient oxygen supply, promoting healthy root development.
2.Chemical stability: It is chemically stable and will not release harmful substances into the nutrient solution. This ensures that the growth environment of plants is clean and safe, and will not cause any negative impacts on plant growth.
Durability: Our volcanic rock is durable and can be reused for multiple crop cycles, which is cost effective for large scale soilless cultivation operations.
Applications in Soilless Cultivation
1.Seedling raising: It provides a stable and well drained substrate for seedlings. The proper porosity helps the young roots to penetrate easily and absorb water and nutrients efficiently.
2.Hydroponic systems: In hydroponic setups, volcanic rock can be used as a medium to support the plants. It can be placed in containers or beds, and when combined with the nutrient rich solution, it creates an ideal growth environment for various plants, such as lettuce, tomatoes, and herbs.
Aeroponic systems: Even in more advanced aeroponic systems, volcanic rock can play a role. It can be used as a supplementary material to help regulate the humidity and temperature around the roots, further enhancing the growth performance of plants.
Storage and Packaging
1.Storage: It should be stored in a dry and ventilated place to avoid moisture and pollution.
2.Packing: generally packed in paper bag or plastic bag, also can be customized according to customer's demand.
Regular Packaging:
1.bulk bags
2.25kg bags,50kg bags in 1 ton bag or on pallet
