planting cubes rockwool have a strong ability of water saving and fertilizer retention. It provides an excellent growth environment for crop roots. The internal three-dimensional network fiber structure makes the nutrient distribution more evenly, which is conducive to the roots extension and growth. A developed root system is the precondition of high yield and excellent fruit quality.
UPuper® Rock wool has firm structure and is not easy to deform without scattering, so It will not cause any damage to crops root while transplanting, the survival rate will increase, which is also helpful to grow large seedlings. It can help to realize the time to market  in advance or later seasons to bring higher yield, quality and economic benefits.

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

planting cubes rockwool 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.

2.About planting cubes rockwool,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.

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

Yes, planting cubes rockwool 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.

4.About planting cubes rockwool,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.

5.How are planting cubes rockwool sterilized and prepared for safe use in plant cultivation?

planting cubes rockwool 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.

6.How do you prepare planting cubes rockwool for planting, and what pre-soaking or conditioning steps are recommended?

UPuper is centered on customers and always pay attention to customers' needs for planting cubes rockwool products.We provide these suggestions:
1. Pre-soak the rockwool cubes in a nutrient solution for 15-20 minutes. This will help to ensure that the cubes are evenly saturated with water and nutrients.
2. Rinse the cubes with clean water to remove any excess nutrient solution.
3. Place the cubes in a tray or container and fill with water until the cubes are completely submerged.
4. Allow the cubes to soak for 24-48 hours. This will help to ensure that the cubes are fully hydrated and ready for planting.
5. Once the cubes are fully hydrated, drain off any excess water and plant your seeds or cuttings.

7.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.

8.What is the composition and material of planting cubes rockwool, and how do they compare to other growing mediums like soil or coco coir?

planting cubes rockwool are made from a combination of basalt and chalk that is melted and spun into fibers. The fibers are then compressed into cubes. Rockwool is a great growing medium because it is sterile, lightweight, and provides excellent drainage and aeration. It also holds moisture well and is pH neutral. Compared to soil, rockwool is much lighter and easier to work with, and it does not contain any of the pests or diseases that can be found in soil. Compared to coco coir, rockwool is more sterile and does not contain any of the salts that can be found in coco coir. Rockwool is also more lightweight and easier to work with than coco coir.

9.What are the key considerations for matching the size of planting cubes rockwool to the specific plant species being cultivated?

As a planting cubes rockwool 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.

10.Are planting cubes rockwool suitable for both soil-based and soilless growing systems?

Yes, planting cubes rockwool 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.

11.How do planting cubes rockwool help prevent overwatering or waterlogged conditions in plant root systems?

planting cubes rockwool 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.
