Why choose us?

UPuper® rock wool substrate comes from the demand for soilless cultivation substrates in Sunqiao Modern Agricultural Park, which is the Chinese first agriculture facility base. The first generation of rock wool substrates was born in 1998. In 2005, the structure and performance of rock wool were further upgraded. It leads to the successful development of the second generation rock wool substrates. In 2012, we carried out scientific research cooperation with the national experimental base and UPuper® was recognized. With the development of domestic agriculture facility, soilless cultivation substrates began to be selected by growers. In 2016, the third generation rock wool substrates were successfully upgraded. On the premise of growers’ easy use, the products were further subdivided. UPuper® developed a series of products that are suitable for different crops and different growth stages, with multiple specifications to meet the various needs of different growers. Growers can also choose to customize products according to their actual situation. After more than 20 years of continuous exploration, R & D and practical application in the field of substrates, after three generations of improvement, UPuper® combined with the actual needs of growers, rock wool substrates has been developed into different items for different application fields such as agriculture facility, three-dimensional greening and potted plants to cover much more industries.

hydroponic rockwool cubes--A Guide to Frequently Asked Questions

1.Do rockwool grow cubes have different densities or compositions for use in various growing stages, such as seed germination or flowering?

Yes, rockwool grow cubes can have different densities and compositions for use in various growing stages. For example, some rockwool cubes are designed specifically for seed germination, while others are designed for flowering. The density and composition of the rockwool cubes can vary depending on the type of plant being grown and the desired outcome.

2.Are rockwool grow cubes pH-neutral, and do they require any adjustments before use?

Rockwool grow cubes are generally pH-neutral and do not require any adjustments before use. However, it is recommended to check the pH of the cubes before use to ensure they are at the desired level.

3.How do rockwool grow cubes provide a stable and consistent environment for plant roots?

Rockwool grow cubes provide a stable and consistent environment for plant roots by providing a medium that is well-aerated, well-draining, and retains moisture. The cubes are made of a spun mineral fiber that is highly absorbent and can hold up to 20 times its weight in water. This helps to keep the root zone consistently moist and well-aerated, which is essential for healthy root growth. The cubes also provide a stable environment for the roots, as they are not prone to shifting or compressing like other growing media.

4.Do rockwool grow cubes have natural resistance to pests and diseases in horticultural settings?

No, rockwool grow cubes do not have natural resistance to pests and diseases in horticultural settings. It is important to use proper pest and disease control measures to ensure healthy plants.

5.What applications can rockwool grow cubes be used for?

Rockwool grow cubes can be used for a variety of applications, including hydroponic gardening, seed starting, cloning, and propagation. They are also commonly used in aeroponic systems, as well as for growing mushrooms.

6.How are rockwool grow cubes sterilized and prepared for safe use in plant cultivation?

Rockwool grow cubes are typically sterilized using a combination of heat and steam. The cubes are placed in a steam chamber and heated to a temperature of around 180°F (82°C) for a period of time. This process kills any bacteria, fungi, and other microorganisms that may be present in the cubes. After sterilization, the cubes are then soaked in a nutrient solution to prepare them for use in plant cultivation.

7.What is the composition and material of rockwool grow cubes, and how do they compare to other growing mediums like soil or coco coir?

Rockwool grow cubes are made from a combination of basalt and chalk that is melted and spun into fibers. The fibers are then compressed into cubes. Rockwool is a great growing medium because it is sterile, lightweight, and provides excellent drainage and aeration. It also holds moisture well and is pH neutral. Compared to soil, rockwool is much lighter and easier to work with, and it does not contain any of the pests or diseases that can be found in soil. Compared to coco coir, rockwool is more sterile and does not contain any of the salts that can be found in coco coir. Rockwool is also more lightweight and easier to work with than coco coir.

8.Are there rockwool grow cube products specifically designed for vertical gardening or living walls?

Yes, there are rockwool grow cubes specifically designed for vertical gardening and living walls. These cubes are designed to provide optimal air and water retention, as well as support for the plants. They are available in various sizes and shapes to fit any vertical gardening or living wall setup.

9.What are the key considerations for matching the size of rockwool grow cubes to the specific plant species being cultivated?

1. Plant size: The size of the rockwool cubes should be matched to the size of the plant. For example, larger plants will require larger cubes, while smaller plants will require smaller cubes. 2. Plant root system: The size of the rockwool cubes should also be matched to the size and complexity of the plant’s root system. For example, plants with larger and more complex root systems will require larger cubes. 3. Plant growth rate: The size of the rockwool cubes should also be matched to the plant’s growth rate. For example, plants with faster growth rates will require larger cubes. 4. Plant nutrient requirements: The size of the rockwool cubes should also be matched to the plant’s nutrient requirements. For example, plants with higher nutrient requirements will require larger cubes. 5. Plant water requirements: The size of the rockwool cubes should also be matched to the plant’s water requirements. For example, plants with higher water requirements will require larger cubes.

10.Can rockwool grow cubes be reused, and what is the recommended cleaning and sterilization process for multiple growing cycles?

Yes, rockwool grow cubes can be reused. The recommended cleaning and sterilization process for multiple growing cycles is to soak the cubes in a 10% bleach solution for 10 minutes, rinse them thoroughly with clean water, and then allow them to dry completely before reusing.

11.How do you monitor and maintain proper moisture levels within rockwool grow cubes throughout the plant's growth cycle?

1. Monitor the moisture levels of the rockwool cubes regularly. Use a moisture meter to measure the moisture content of the cubes. 2. Adjust the watering schedule accordingly. If the cubes are too dry, water more frequently. If the cubes are too wet, water less frequently. 3. Use a humidity dome or tray to help maintain proper moisture levels. 4. Consider using a hydroponic system to provide a more consistent moisture level. 5. Add a layer of perlite or vermiculite to the top of the rockwool cubes to help retain moisture. 6. Consider using a fan to help circulate air and reduce humidity.

12.Can rockwool grow cubes be used in combination with traditional soil to improve aeration and drainage in potted plants?

Yes, rockwool grow cubes can be used in combination with traditional soil to improve aeration and drainage in potted plants. Rockwool is a lightweight, porous material that helps to improve drainage and aeration in soil, allowing for better root growth and healthier plants. It can also help to retain moisture in the soil, which is beneficial for plants that require more frequent watering.
