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.What is the water retention capacity of planting in rockwool cubes, and how does this impact plant hydration and growth?

planting in rockwool cubes have a water retention capacity of approximately 80-90%. This means that the cubes can absorb and hold a large amount of water, which helps to keep the plant hydrated and promote healthy growth. The high water retention capacity also helps to reduce the amount of water needed for irrigation, as the cubes can slowly release the stored water to the plant over time.

2.What types of crops or plants are best suited for cultivation in planting in rockwool cubes, and are there any limitations?

planting in rockwool cubes are best suited for hydroponic cultivation of vegetables, herbs, and flowers. Some of the most popular crops grown in rockwool cubes include tomatoes, peppers, cucumbers, lettuce, and basil. Rockwool cubes can also be used to propagate cuttings from existing plants.
The main limitation of rockwool cubes is that they are not suitable for growing root vegetables such as potatoes, carrots, and onions. Additionally, rockwool cubes are not suitable for growing plants that require a lot of water, such as watermelons and pumpkins.

3.As a planting in rockwool cubes manufacturer, What about your package?

Export standard package. Cartons tested for compressive strength. Pallet packaging is also acceptable.

4.About planting in rockwool cubes,Should I water from the top or root of the plant?

Seedling raise can use the tidal seedbed and the drip irrigation control system used after transplanting. Those processes are watered from below the plant and close to the root.

5.Are there any concerns or precautions related to the health and safety of growers working with planting in rockwool cubes, including dust or fiber exposure?

Yes, there are health and safety concerns related to working with rockwool grow cubes. Rockwool is made from melted basaltic rock and chalk, and when it is cut or handled, it can release dust and fibers into the air. This dust and fiber can be inhaled and can cause irritation to the eyes, nose, and throat.
It can also cause skin irritation and respiratory problems. Therefore, it is important to wear protective gear such as a dust mask, safety glasses, and gloves when handling rockwool. Additionally, it is important to ensure that the work area is well-ventilated and that the rockwool is kept away from food and drink.

6.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.

7.Are there organic or sustainable options for planting in rockwool cubes that meet eco-friendly growing practices?

Yes, there are several organic and sustainable options for rockwool grow cubes that meet eco-friendly growing practices. These include organic rockwool cubes made from natural materials such as coconut coir, hemp, and jute, as well as sustainable rockwool cubes made from recycled materials. Additionally, some companies offer rockwool cubes that are treated with natural, non-toxic solutions to reduce the risk of disease and pests.

8.Are planting in rockwool cubes compatible with automatic irrigation and nutrient delivery systems commonly used in hydroponics?

Yes, planting in rockwool cubes 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.
