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.
8 inch 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.
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.
We are deeply concerned about every footprint's impact of our products on the natural ecological environment. By combining with existing ecological situation and natural environmental problems, UPuper® has an in-depth insight into the market demand for Rock wool substrates to realize continuously optimizations and upgrades. From production at the front to recycling at the back-end process, we are following our belief to providing high-quality products and services for growers and practicing the concept of sustainable development.

8 inch rockwool cubes--A Guide to Frequently Asked Questions
1.What types of fertilizers and nutrients are commonly used with rockwool grow cubes?
Common fertilizers and nutrients used with rockwool grow cubes include:
-Organic fertilizers such as fish emulsion, kelp meal, and compost tea
-Synthetic fertilizers such as 20-20-20, 15-30-15, and 10-52-10
-Micronutrients such as iron, zinc, and manganese
-Calcium and magnesium supplements
-pH adjusters such as lime or sulfur
2.How are 8 inch rockwool cubes sterilized and prepared for safe use in plant cultivation?
8 inch rockwool 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.
3.Can rockwool grow cubes be used for cloning and propagating plant cuttings, and what advantages do they offer for this purpose?
Yes, rockwool grow cubes can be used for cloning and propagating plant cuttings. Rockwool is a great medium for cloning and propagating because it is sterile, lightweight, and provides excellent aeration and drainage. It also holds moisture well, which is important for successful cloning and propagation. Additionally, rockwool is easy to use and can be cut to fit any size container.
4.How are rockwool grow cubes used in horticulture and hydroponics?
Rockwool grow cubes are used in horticulture and hydroponics as a medium for growing plants. They are made from spun basalt rock and chalk, and are lightweight, sterile, and easy to use. The cubes provide an ideal environment for root growth, and can be used to start seeds, propagate cuttings, and grow plants from seedlings. They are also used to support hydroponic systems, as they can hold water and nutrients, and provide an ideal environment for root growth.
5.What are rockwool grow cubes?
Rockwool grow cubes are a type of growing medium made from melted basalt rock and chalk that is spun into fibers and then compressed into cubes. They are commonly used in hydroponic systems and are known for their excellent water retention and air porosity. Rockwool cubes are also pH neutral, making them ideal for growing a variety of plants.
6.How do you prepare rockwool grow cubes for planting, and what pre-soaking or conditioning steps are recommended?
1. Pre-soak the rockwool cubes in a nutrient solution for 15-20 minutes. This will help to ensure that the cubes are evenly saturated with water and nutrients.
2. Rinse the cubes with clean water to remove any excess nutrient solution.
3. Place the cubes in a tray or container and fill with water until the cubes are completely submerged.
4. Allow the cubes to soak for 24-48 hours. This will help to ensure that the cubes are fully hydrated and ready for planting.
5. Once the cubes are fully hydrated, drain off any excess water and plant your seeds or cuttings.
7.Do 8 inch rockwool cubes have different densities or compositions for use in various growing stages, such as seed germination or flowering?
Yes, 8 inch rockwool 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.
8.What is soilless cultivation?
Soilless cultivation is a method of cultivating plants without natural soil nor use compound fertilizer and similar compound fertilizer based on soil. It is a new method that only uses nutrient solution to support for plant growth or various cultivation substrates that can replace soil and are suitable for plant growth. Soilless cultivation can be divided into fog cultivation, water cultivation and solid substrate cultivation. UPuper® Rock wool substrate belongs to solid substrate cultivation.
9.Can rockwool grow cubes be used in combination with alternative growing methods like aeroponics or deep water culture (DWC)?
Yes, rockwool grow cubes can be used in combination with alternative growing methods like aeroponics or deep water culture (DWC). Rockwool cubes are a great medium for starting seeds and cuttings, and can be used in combination with other growing methods to provide a stable environment for the roots to develop. Rockwool cubes can also be used to provide additional aeration and drainage for plants grown in aeroponics or DWC systems.
10.Are rockwool grow cubes suitable for both soil-based and soilless growing systems?
Yes, rockwool grow cubes are suitable for both soil-based and soilless growing systems. Rockwool is a great medium for both types of systems because it is lightweight, sterile, and provides excellent drainage and aeration. It also holds moisture well, making it an ideal choice for both types of systems.
