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.As a hydro grow cubes manufacturer, How to control the EC Value of rock wool planting strip?

The rock wool cultivation strip itself does not contain any nutrients, so it only needs to adjust the nutrient supply according to the EC value required by each growth stage of the crops. At the same time, growers can make small and frequent changes in the irrigation strategies (for example, when the EC is too high, multiple slight adjustments are more convenient and safe than large adjustments).

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

Yes, hydro 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.

3.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.

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

UPuper is a professional hydro 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.

5.What sizes and shapes do hydro grow cubes come in, and how do these variations affect their applications?

hydro grow cubes 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.

6.About hydro 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.Do hydro 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.

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

Yes, hydro grow 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.

9.How do hydro grow cubes help prevent overwatering or waterlogged conditions in plant root systems?

hydro grow cubes are made of a porous material that helps to regulate the amount of water that is available to the plant roots. The material is designed to absorb and retain water, while also allowing excess water to drain away. This helps to prevent overwatering and waterlogged conditions in the root system, as the plant is able to take up only the amount of water it needs.

10.As a hydro 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.

11.How are hydro grow cubes sterilized and prepared for safe use in plant cultivation?

hydro grow 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.
