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 environmental conditions, such as temperature and humidity, are optimal for using pre soaking rockwool cubes in indoor or outdoor growing setups?

The optimal environmental conditions for using rockwool grow cubes in indoor or outdoor growing setups are temperatures between 65-75°F (18-24°C) and humidity levels between 40-60%. It is important to maintain these conditions to ensure the best results for your plants.

2.As a pre soaking rockwool cubes manufacturer,What's the term of payment?

T/T, Paypal, Credit card etc.

3.How do you monitor and maintain proper moisture levels within pre soaking rockwool cubes 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.

4.What is the expected lifespan of pre soaking rockwool cubes, and how do you determine when it's time to replace them?

The expected lifespan of pre soaking rockwool cubes 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.

5.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.

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

UPuper is centered on customers and always pay attention to customers' needs for pre soaking rockwool cubes 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.What is the composition and material of pre soaking rockwool cubes, and how do they compare to other growing mediums like soil or coco coir?

pre soaking rockwool cubes 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.

8.Can pre soaking rockwool cubes be used in combination with alternative growing methods like aeroponics or deep water culture (DWC)?

Yes, pre soaking rockwool cubes 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.

9.As a pre soaking rockwool 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).

10.Do pre soaking rockwool cubes have different densities or compositions for use in various growing stages, such as seed germination or flowering?

Yes, pre soaking rockwool cubes can have different densities and compositions for use in various growing stages. For example, some rockwool cubes are designed specifically for seed germination, while others are designed for flowering. The density and composition of the rockwool cubes can vary depending on the type of plant being grown and the desired outcome.
