UPuper® Rock wool does not carry, absorb or consume any water or nutrients. Meanwhile, rockwool cube 5x5 does not prevent crops from absorbing nutrients. The elements given by water and fertilizer can be totally provided to plants. Growers do not need to consider the various effects of the substrates itself on crops.
People can accurately mix the nutrition solution required by crops in each growing stage. It is conducive to the data collection, analysis and management to optimize planting strategies. UPuper® rock wool’s EC and pH values are stable, which is convenient to set a unified irrigation scheme to have an easier management, and keep the consistent growth of crop roots.

Instructions for using rockwool cubes:
1. Soak the rockwool cubes in warm water to fully foam.
2. Put the rockwool cubes into a container and distribute evenly.
3. Place the seeds gently on the surface in the correct direction and wrap them in rockwool cubes, as the frosted rockwool  grow cubes can absorb enough water to ensure sufficient moisture coverage of the plant roots.
4. Depending on the variety of plants, they can grow new roots under the support of external plant sprouting cloths, achieving germination.
5. Put the sprouted cloth blocks of plants back into the container and replenish them with water in a timely manner.


Uniform water content and electrical conductivity distribution throughout cubes.
Grooves can facilitate water drainage and provide air pruning on root system.
Rapid root system development.

1.How do rockwool cube 5x5 compare to traditional soil in terms of plant growth rates and yields?

rockwool cube 5x5 are a great alternative to traditional soil for growing plants. They provide excellent aeration and drainage, which can lead to faster growth rates and higher yields. Rockwool also has a higher water-holding capacity than soil, which can help to reduce the amount of water needed for plants. Additionally, rockwool is sterile, so it is less likely to contain disease-causing organisms that can harm plants. Overall, rockwool grow cubes can provide a great environment for plants to thrive in, leading to faster growth rates and higher yields.

2.What are the key considerations for matching the size of rockwool cube 5x5 to the specific plant species being cultivated?

As a rockwool cube 5x5 manufacturer, UPUPER will tell you the following factors:
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.

3.Are rockwool cube 5x5 suitable for both soil-based and soilless growing systems?

Yes, rockwool cube 5x5 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.

4.As a rockwool cube 5x5 manufacturer,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.

5.How do rockwool cube 5x5 contribute to root stability and prevent transplant shock when moving plants to larger containers?

Rockwool grow cubes provide a stable environment for roots to grow and develop. The cubes are designed to hold moisture and nutrients, which helps to reduce transplant shock and promote healthy root growth. The cubes also provide a physical barrier between the roots and the new container, which helps to reduce the risk of root damage during the transplant process. Additionally, the cubes help to keep the roots in place, which helps to prevent the plant from becoming uprooted during the transplant process.

6.As a rockwool cube 5x5 manufacturer,UPuper® Rock wool recycling service

UPuper® Rockwool cubes can be recycled. Used UPuper® rock wool can be recycled back to the production lines. After separating and melting with other raw materials. Those used products can be made into new rock wool. The products that made of recycled materials have no quality difference from the new ones, and can be re-applied to thermal insulation, fire prevention and noise reduction in the fields of construction, industry and ships.

7.What sizes and shapes do rockwool cube 5x5 come in, and how do these variations affect their applications?

rockwool cube 5x5 come in a variety of sizes and shapes, including cubes, slabs, and blocks. The size and shape of the cube will affect the application, as different sizes and shapes are better suited for different types of plants. For example, cubes are great for starting seeds, while slabs are better for larger plants. Blocks are ideal for hydroponic systems, as they provide more surface area for the roots to grow. The shape of the cube also affects the amount of air and water that can be held, which can be beneficial for certain types of plants.

8.Are rockwool cube 5x5 compatible with automatic irrigation and nutrient delivery systems commonly used in hydroponics?

Yes, rockwool cube 5x5 are compatible with automatic irrigation and nutrient delivery systems commonly used in hydroponics. However, it is important to note that rockwool cubes should be soaked in water before use to ensure that they are properly hydrated. Additionally, rockwool cubes should be flushed with water every few weeks to prevent nutrient buildup.

9.How do rockwool cube 5x5 promote aeration in the root zone, and what benefits does this offer for plant health?

rockwool cube 5x5 promote aeration in the root zone by providing a porous, airy environment for the roots to grow in. This helps to ensure that the roots have access to oxygen, which is essential for healthy root growth and development. The increased aeration also helps to reduce the risk of root rot and other diseases, as well as promoting better nutrient uptake. Additionally, the increased aeration helps to regulate the temperature of the root zone, which can help to protect the plant from extreme temperatures.
