CB 100L Cultivation Block - Upuper Rockwool

The UPuper® CB 100L Growing Cubes are designed to provide an ideal environment for seedlings and cuttings, promoting healthy root development and robust plant growth. Each cube measures 4 x 4 x 4 inches (L x W x H) and features a φ1-inch hole with a depth of 1.38 inches, along with grooves for efficient water drainage and air pruning of the root system. The cubes are individually wrapped in white film to maintain their shape during transplanting and prevent algae growth.

These cubes boast a water absorption rate of >=900% and a low organic matter content of <1.5%, meeting GMP hygiene requirements with no detectable levels of toxic and harmful heavy metals. They are designed to provide uniform water and electrical conductivity distribution throughout, ensuring optimal growing conditions for your plants.

The UPuper® CB 100L Growing Cubes are compatible with UPuper® CP T25, CP T36, and CP R20 starter plugs, which fit snugly into the pre-formed hole on the top of the cube. This makes them an ideal intermediary container for cannabis planting, offering a convenient and effective solution for growers.

Practice Tips:

1. Pre-soak the cubes before use to ensure proper hydration.
2. Adjust the pH of the growing medium to the range of 5.5-6.5 for optimal cannabis growth.
3. The wrapping of the cubes can be removed, cut, and mixed with the soil to improve soil aeration.
