UPuper Rockwool

While these cubes are excellent for propagation and cloning, their 6x6x6 size makes them substantial enough to support plants through a significant portion of their vegetative stage. They are designed to provide a stable, long-term root environment for hydroponic or soil-less systems.

The UV-resistant sleeves are designed to block light from reaching the rockwool surface, which effectively prevents algae growth. This keeps your root zone cleaner and reduces the need for frequent maintenance or cleaning of your growing medium.

Because these cubes are designed to hold moisture efficiently, you should monitor your drainage closely to avoid over-saturation. It is best to allow the cubes to dry out slightly between waterings to ensure the roots receive adequate oxygen.

These cubes are engineered primarily for hydroponic and soil-less cultivation. While they can be transplanted into soil, they perform best in systems where you can control the moisture levels and nutrient delivery directly.

Yes, it is standard practice to soak rockwool in a pH-adjusted solution before use. This ensures the medium is at the correct acidity level for your plants and helps prime the fibers for optimal moisture absorption.
