Select Grow Media for Commercial Use

It is a common practice for the commercial grower to transition fresh cuttings into plugs for the first stage of the growing process for roots to grow healthy and strong. Once the plants have well established root systems, they can be transplanted into a larger stonewool application such as a block or slab. It is essential to allow plants to grow healthy roots that are well supported in the start of the growing process, but also during the entire life cycle of the plant. It is a common practice to stack slabs or blocks to allow for an even larger growing area for roots to allow for access to plenty of nutrients and water. RedRock Block are designed with the grower in mind making sure that plants stay happy and healthy which in turn means a more stable growing season with more predictable quality and production.
