Grodan Expert 20/75 Slab: Ultimate Planting Solution

Introducing the Grodan Expert 20/75 Slab, a cutting-edge hydroponic solution designed for professional and hobbyist gardeners alike. This case of 12 slabs measures 36" x 8" x 3", providing ample space for larger, long-term crops. Made from high-quality Grodan Stonewool, these slabs are engineered to support plant growth at every stage. With their unique vertical fibers, they offer exceptional drainage and aeration, ensuring optimal root development.

Product Properties and Specifications

Each Grodan Expert 20/75 Slab is crafted with precision, featuring UV-resistant poly sleeves for durability and ease of use. The vertical fiber design allows for rapid drainage, making them ideal for hydroponic systems. The slabs are available in a Grodan Master version, which features a special wet/dry slab technology. This innovative design has a thicker top layer that stays wetter and a bottom layer that stays drier, ensuring a more even distribution of moisture throughout the slab. Key features include:

  • Vertical fibers for rapid drainage and aeration
  • UV-resistant poly sleeves for durability
  • Master wet/dry slab technology for even moisture distribution

Practical Uses and Benefits

Whether you're growing peppers, tomatoes, or cucumbers, the Grodan Expert 20/75 Slabs are the perfect choice for your hydroponic setup. Their graduated sizes make them versatile for seedlings started in cubes, blocks, or directly into slabs. The ease of transplantation from cubes to blocks and then to slabs ensures a seamless growing process. These slabs are not only suitable for hydroponic systems but can also be used with traditional planters and growing mediums. Benefits include:

  • Optimal root development due to excellent drainage and aeration
  • Seamless transplantation process from cubes to blocks and slabs
  • Versatility for use in hydroponic systems and traditional planters
