CM 15 Pro Cultivation Block - Upuper Rockwool

The UPuper® 6-inch Rockwool cubes are designed to provide ample growing volume for larger plants. They feature a standard-size pre-cut planting hole for easy transplanting. The cubes come with a wetting agent for immediate plant nutrient availability and high fiber density, which efficiently utilizes water and fertilizers while allowing for dry periods. These grow blocks are known for their uniformity, eliminating the need for proprietary tables and allowing growers to customize their growing space at a fraction of the cost. The cubes are designed for precise planting control, reducing stall and shortening the harvest cycle. They are packaged in photodegradable, UV-resistant sleeves for easy handling and algae prevention. The holes in the grow blocks are perfectly sized for any 1.5-inch starter plug.

Application:

These blocks are typically used in the final stage of cannabis planting. They can also be placed directly on the grow slab to allow roots to continue growing from the block to the slab.

Practice Tips:

1. Pre-soak the blocks before use.
2. Adjust the pH of the growing medium to 5.5-6.5 for cannabis planting.
3. The wrapping of the grow block can be removed, cut, and mixed with the soil to improve soil aeration.
