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.


Give roots more growing space.Better water and fertilizer retention.

1.As a rockwool planter blocks manufacturer, What about your package?

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

2.Can rockwool planter blocks be used for cloning and propagating plant cuttings, and what advantages do they offer for this purpose?

Yes, rockwool planter blockss 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.

3.What types of fertilizers and nutrients are commonly used with rockwool planter blocks?

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

4.How do rockwool planter blocks provide a stable and consistent environment for plant roots?

rockwool planter blocks 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.

5.Can rockwool planter blocks be used in combination with alternative growing methods like aeroponics or deep water culture (DWC)?

Yes, rockwool planter blocks 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.

6.As a rockwool planter blocks manufacturer,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.

7.About rockwool planter blocks,Why should we open some drains on the rock wool cultivation strip?

The drain is opened at the bottom of both ends of the cultivation strip. The drain is opened to allow the normal discharge of excess water and fertilizer to keep the EC Value in the planting strip stable. The location of drainage holes and the correct irrigation amount directly affect the distribution of water and EC in the cultivation strip. Be sure not to set additional drainage holes in the planting strip when you use them, otherwise it will change the planting strip drainage mode, which may be unfavorable to the plant roots in some areas in the planting strip. The surplus water and fertilizer will flow into the diversion tank and return to the irrigation system for recycling after disinfection and other process. It can not only solve the problem of water and fertilizer, but also protect the environment.

8.How are rockwool planter blocks sterilized and prepared for safe use in plant cultivation?

rockwool planter blocks 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.

9.What is the expected lifespan of rockwool planter blocks, and how do you determine when it's time to replace them?

The expected lifespan of rockwool planter blocks is typically between 1-3 years, depending on the frequency of use and the quality of the cubes. To determine when it's time to replace them, look for signs of wear and tear such as discoloration, cracking, or crumbling. If the cubes are no longer providing adequate support for the roots of your plants, it's time to replace them.
