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 are the disposal and recycling options for used coco grow cubes, and are they environmentally responsible?

coco grow cubes are made from a combination of basalt and slag, which are both non-toxic and non-hazardous materials. The best way to dispose of used rockwool grow cubes is to recycle them. Many local recycling centers accept rockwool grow cubes for recycling. Alternatively, you can contact your local waste management company to see if they offer a special collection service for rockwool grow cubes.
Recycling rockwool grow cubes is an environmentally responsible option as it reduces the amount of waste that goes to landfills. Additionally, recycling rockwool grow cubes helps conserve resources and reduce the amount of energy needed to produce new materials.

2.How do you prevent the formation of algae or mold on the surface of coco grow cubes?

To avoid causing losses due to these issues, UPuper recommends that you do the following:
1. Make sure to keep the rockwool grow cubes in a well-ventilated area.
2. Avoid overwatering the rockwool grow cubes.
3. Clean the rockwool grow cubes regularly with a mild detergent and water solution.
4. Use a fungicide or algaecide to prevent the formation of algae or mold.
5. Make sure to keep the rockwool grow cubes away from direct sunlight.

3.About coco grow 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.

4.Do coco grow cubes have natural resistance to pests and diseases in horticultural settings?

No, rockwool grow cubes do not have natural resistance to pests and diseases in horticultural settings. It is important to use proper pest and disease control measures to ensure healthy plants.

5.Can coco grow cubes be reused, and what is the recommended cleaning and sterilization process for multiple growing cycles?

Yes, coco 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.

6.About coco grow cubes,What is the best time of for daily irrigation?

It depends on your region and season.
In case of similar climate conditions in Shanghai, it is recommended to start watering 2 hours after sunrise and stop watering 2-3 hours before sunset. Long term watering before sunset will lead to plant overgrowth. If necessary (in hot climate for example), please adjust your irrigation strategy in time to keep the water absorbed by plants consistent and grow evenly every day.

7.As a coco grow cubes manufacturer,What's the term of payment?

T/T, Paypal, Credit card etc.

8.As a coco grow cubes manufacturer, How to ship the goods to the customer?

DHL , USP , FedEx , EMS , by air , by sea , and customer's forwarder are also acceptable.

9.Is it possible to get samples of the coco grow cubes for you?

Yes, we can provide samples for your quality testing.

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

Yes, coco 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.

11.How do coco grow cubes accommodate different irrigation methods, including drip systems, flood and drain, or ebb and flow?

coco grow cubes can accommodate different irrigation methods by providing a variety of sizes and shapes to fit different systems. For example, the cubes can be cut to fit a drip system, or they can be used in a flood and drain system by providing a larger surface area for water to flow through. For an ebb and flow system, the cubes can be used to create a platform for the plants to sit on, allowing the water to flow around them.

12.How do coco grow cubes 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.

13.What are the common challenges or issues that growers may encounter when using coco grow cubes, and how can they be mitigated?

UPuper is a professional coco grow cubes manufacturer and may encounter these issues. We provide corresponding suggestions:
1. Poor drainage: Rockwool cubes can become waterlogged if not properly drained. To mitigate this, growers should ensure that the cubes are placed in a tray with adequate drainage holes and that the cubes are not over-watered.
2. pH imbalance: Rockwool cubes can become too acidic or alkaline if not properly managed. To mitigate this, growers should regularly check the pH of the cubes and adjust as needed.
3. Nutrient deficiencies: Rockwool cubes can become nutrient deficient if not properly managed. To mitigate this, growers should regularly check the nutrient levels of the cubes and adjust as needed.
4. Pest infestations: Rockwool cubes can become infested with pests if not properly managed. To mitigate this, growers should regularly inspect the cubes for signs of pests and take appropriate action if necessary.

14.What applications can coco grow cubes be used for?

coco grow cubes can be used for a variety of applications, including hydroponic gardening, seed starting, cloning, and propagation. They are also commonly used in aeroponic systems, as well as for growing mushrooms.

15.As a coco grow cubes manufacturer,UPuper® Rock wool recycling service
