Grodan Expert 20/75 Slab

Introducing the Grodan Expert 20/75 Slab, a top-tier solution for your hydroponic needs. This product is designed for larger, long-term crops with extensive root systems, making it an ideal choice for peppers, tomatoes, or cucumbers. The Grodan Stonewool (rockwool) technology used in this slab is unparalleled, offering exceptional nutrient absorption and oxygen retention, which are crucial for rapid plant growth.
  • Unique Fiber Technology - Grodan Stonewool is made from molten rock spun into fibers, then compressed into cubes, blocks, or slabs. This process ensures that each Grodan slab is uniquely tailored to support plants in different growth stages.
  • Optimized for Hydroponics - The vertical fibers of the Grodan Expert 20/75 Slab allow for the fastest drainage among Grodan slabs, making it perfect for hydroponic systems where rapid drainage is essential.

Practical and User-Friendly Design

The Grodan Expert 20/75 Slab is not just a technical marvel; it's also incredibly user-friendly. The slabs come in clearly marked UV-resistant poly sleeves, making them easy to handle and use. This design feature is especially beneficial for beginners and seasoned hydroponic enthusiasts alike.
  • Graduated Sizes - Grodan offers graduated sizes, allowing seedlings to easily transition from cubes to blocks and finally onto slabs, ensuring a seamless growing process.
  • Flexible Application - Seedlings or cuttings started in Grodan cubes can be transplanted into more traditional planters and growing mediums, providing flexibility and convenience.

Superior Performance and Sustainability

The Grodan Expert 20/75 Slab is not just a tool for plant growth; it's a commitment to sustainability. The high-quality materials and thoughtful design ensure that this slab will last through multiple growing cycles, reducing waste and environmental impact.
  • Special Wet/Dry Slab - Grodan Master slabs feature a wet/dry design, with a thicker top layer that stays wetter and a drier bottom layer, ensuring even moisture distribution throughout the slab.
  • Longevity and Versatility - The durable construction and versatile application of Grodan slabs make them a long-term investment for any hydroponic setup.
