growing cubes outdoors 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.

growing cubes outdoors 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.
