UPuper® Rock wool does not carry, absorb or consume any water or nutrients. Meanwhile, growing geranium plug plants does not prevent crops from absorbing nutrients. The elements given by water and fertilizer can be totally provided to plants. Growers do not need to consider the various effects of the substrates itself on crops.
People can accurately mix the nutrition solution required by crops in each growing stage. It is conducive to the data collection, analysis and management to optimize planting strategies. UPuper® rock wool’s EC and pH values are stable, which is convenient to set a unified irrigation scheme to have an easier management, and keep the consistent growth of crop roots.

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.


Individually wrapped cubes hold the rockwool’s shape and prevent algae growth.
Easy to transport without hurting the roots and can improve transplanting efficiency.

1.Do growing geranium plug plants have any insulating properties that benefit plant roots in extreme weather conditions?

Yes, growing geranium plug plants do have insulating properties that can benefit plant roots in extreme weather conditions. The insulation helps to keep the root zone temperature more consistent, which can help protect the roots from extreme temperatures. Additionally, the insulation can help to retain moisture in the root zone, which can be beneficial in dry climates.

2.Are growing geranium plug plants compatible with automatic irrigation and nutrient delivery systems commonly used in hydroponics?

Yes, growing geranium plug plants 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.

3.How do growing geranium plug plants provide a stable and consistent environment for plant roots?

growing geranium plug plants 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.

4.As a growing geranium plug plants manufacturer, What about your package?

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

5.Do growing geranium plug plants 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.

6.How do you prepare growing geranium plug plants for planting, and what pre-soaking or conditioning steps are recommended?

UPuper is centered on customers and always pay attention to customers' needs for growing geranium plug plants 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.Can growing geranium plug plants be used in conjunction with other growing media or as part of a multi-stage cultivation process?

Yes, growing geranium plug plants can be used in conjunction with other growing media or as part of a multi-stage cultivation process. Rockwool cubes are often used in hydroponic systems as a medium for starting seeds or cuttings, and can be used in conjunction with other growing media such as perlite, vermiculite, and coco coir. Rockwool cubes can also be used in multi-stage cultivation processes, such as in aeroponic systems, where the cubes are used to start the seedlings and then transferred to a larger growing medium.

8.As a growing geranium plug plants manufacturer,UPuper® Rock wool recycling service

UPuper® Rockwool cubes can be recycled. Used UPuper® rock wool can be recycled back to the production lines. After separating and melting with other raw materials. Those used products can be made into new rock wool. The products that made of recycled materials have no quality difference from the new ones, and can be re-applied to thermal insulation, fire prevention and noise reduction in the fields of construction, industry and ships.

9.As a growing geranium plug plants 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.

10.About growing geranium plug plants,How to calculate the irrigation amount of nutrient solution?

In case of tomatoes, from planting to flowering: the irrigation amount is about 300-500ml / plant / day; From flowering stage to early fruiting stage: the irrigation amount is about 800-1200ml / plant / day; From early fruiting to harvest period: the irrigation amount is 1200-1500ml / plant / day, and the irrigation amount in full fruit period is about 1500-2000ml / plant / day. You can also bring out a rough calculation according to the shape and size of rock wool.

11.How do you monitor and maintain proper moisture levels within growing geranium plug plants throughout the plant's growth cycle?

UPuper has many years of experience in this industry and can share with you these:
1. Monitor the moisture levels of the rockwool cubes regularly. Use a moisture meter to measure the moisture content of the cubes.
2. Adjust the watering schedule accordingly. If the cubes are too dry, water more frequently. If the cubes are too wet, water less frequently.
3. Use a humidity dome or tray to help maintain proper moisture levels.
4. Consider using a hydroponic system to provide a more consistent moisture level.
5. Add a layer of perlite or vermiculite to the top of the rockwool cubes to help retain moisture.
6. Consider using a fan to help circulate air and reduce humidity.

12.Do growing geranium plug plants require any specific pH and nutrient management practices for optimal plant growth?

Yes, growing geranium plug plants 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.
