UPuper® began to develop rock wool substrates start from the 1990s. So far, it has a history of more than 20 year and been registered in more than 20 countries, UPuper® sales footprints cover all over the world and has been highly recognized by growers locally and abroad.

growing with rockwool cubes substrates have a strong ability of water saving and fertilizer retention. It provides an excellent growth environment for crop roots. The internal three-dimensional network fiber structure makes the nutrient distribution more evenly, which is conducive to the roots extension and growth. A developed root system is the precondition of high yield and excellent fruit quality. UPuper® Rock wool has firm structure and is not easy to deform without scattering, so It will not cause any damage to crops root while transplanting, the survival rate will increase, which is also helpful to grow large seedlings. It can help to realize the time to market  in advance or later seasons to bring higher yield, quality and economic benefits.

In the return liquid of water and fertilizer, there are still a large number of ionized mineral elements that have not been absorbed by the plant. These elements are discharged into the natural environment and become an important pollution source to affect soil and water. Long time ago, developed countries already have paid attention to the pollution impact of water and fertilizer discharge on the environment and take it as the main problem to work with, so they use rock wool as the main substrates because it has less circulating irrigation and less discharge. By using UPuper® Rockwool cubes, the return liquid can be clearer. And the excess water and fertilizer will flow into the diversion tank and return to the irrigation system. After disinfection, it can be 100% recycled, which can not only avoid the waste of water and fertilizer, but also avoid environmental pollution due to informal discharge, especially stop the causing and aggravating the eutrophication of water.

Soil provides living space and important eco system for human, it can store and filter water, intercept pollutants from penetrating into groundwater; but more importantly, soil is a non renewable resource, which is very difficult to repair once it get polluted. In the brief of national soil pollution survey published in 2014, the point exceeding standard rates of eight inorganic pollutants of heavy metals cadmium, mercury, arsenic, copper, lead, chromium, zinc and nickel were 7.0%, 1.6%, 2.7%, 2.1%, 1.5%, 1.1%, 0.9% and 4.8% respectively. In traditional soil planting, there is a large amount of pesticides and fertilizer applying to the plants, which destroys the soil structure and ecological balance, kills the organic organisms in the soil. Those lead to the imbalance and loss of organic matter. UPuper® rock wool is the represent of new soilless cultivation mode. It does not need to worry about soil salinization, hardening or borne diseases etc. It helps to solve the continuous cropping obstacles and protect soil resources from the origin. If soilless cultivation technology is used for plant cultivation, it can not only reduce its burden on the soil, but also give it an effective period for self recovery.

Growing with 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.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.

3.Do rockwool grow cubes require any specific pH and nutrient management practices for optimal plant growth?

Yes, rockwool grow cubes require specific pH and nutrient management practices for optimal plant growth. The ideal pH range for rockwool is between 5.5 and 6.5. Nutrient management should include regular monitoring of the nutrient solution and adjusting the levels as needed. Additionally, it is important to flush the rockwool with fresh water every few weeks to prevent nutrient buildup.

4.Are there specific tools or accessories designed for working with rockwool grow cubes, such as hole punches or plant supports?

Yes, there are several tools and accessories designed specifically for working with rockwool grow cubes. These include hole punches, plant supports, and trays for holding the cubes. Additionally, there are tools for cutting and shaping the cubes, as well as tools for transplanting seedlings from the cubes into larger containers.

5.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.

6.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.

7.How to control the EC Value of rock wool planting strip?

The rock wool cultivation strip itself does not contain any nutrients, so it only needs to adjust the nutrient supply according to the EC value required by each growth stage of the crops. At the same time, growers can make small and frequent changes in the irrigation strategies (for example, when the EC is too high, multiple slight adjustments are more convenient and safe than large adjustments).

8.Why use soilless cultivation?

Soilless cultivation is the most advanced cultivation technology in modern agriculture. From cultivation facilities to environmental control, the whole process can be monitored and regulated according to the needs of crop growth and development. It can realize early maturity and high yield of crops; Production of pollution-free products; greatly improve working conditions, save labor and reduce labor intensity; Save water and fertilizer; Avoid soil continuous planting barriers; it has no regional restrictions and can make the space fully used; so that contribute to the automation and intelligence of cultivation.

9.Do rockwool grow cubes have any insulating properties that benefit plant roots in extreme weather conditions?

Yes, rockwool grow cubes do have insulating properties that can benefit plant roots in extreme weather conditions. The insulation helps to keep the root zone temperature more consistent, which can help protect the roots from extreme temperatures. Additionally, the insulation can help to retain moisture in the root zone, which can be beneficial in dry climates.

10.Can rockwool grow cubes be used in conjunction with other growing media or as part of a multi-stage cultivation process?

Yes, rockwool grow cubes can be used in conjunction with other growing media or as part of a multi-stage cultivation process. Rockwool cubes are often used in hydroponic systems as a medium for starting seeds or cuttings, and can be used in conjunction with other growing media such as perlite, vermiculite, and coco coir. Rockwool cubes can also be used in multi-stage cultivation processes, such as in aeroponic systems, where the cubes are used to start the seedlings and then transferred to a larger growing medium.
