Grodan Stone Wool Gro-Slabs Expert Slab 20/75 8 inch x 3 inch x 36 inch (case of 12)

Grodan Stone Wool Gro-Slabs presents the pinnacle of growth media for those aiming to cultivate impressively large plants. Ideal for hobbyists, the Expert Slab 20/75 has been meticulously crafted with vertical fibers, ensuring faster drainage compared to its Classic counterpart. Each slab is purposefully designed to give your plants the foundation they need to flourish.

When you transplant your Gro-Block plant onto one of these slabs, you're emulating the methods of professional growers worldwide. Here are some key features to note:

1. UV Resistant Sleeves: Each Gro-Slab comes protected in a biodegradable sleeve that resists UV rays. This not only ensures a comfortable handling experience but also plays a crucial role in preventing algae formation.
2. Uni-Slab Design: Every plant root is safeguarded and contained for the entire life of the plant. The Uni-Slab, given its generous dimensions, is perfect for nurturing one large plant, marrying the benefits of a slab and the adaptability of a block.
3. Expert Slabs: Specially designed for hobbyists, the vertical fibers in Expert slabs facilitate faster drainage, giving plants the environment they need for optimal growth.
4. Distinguishable from Classic Slabs: While Expert Slabs are tailored for hobbyists with their vertical fibers, the Classic slabs, with their horizontal fibers, cater to those in hotter and drier climates due to their slower drainage mechanism.
