Grodan Expert Slab, 15/75

Description

Grodan Expert Slab

Grodan Expert Slab can support large plants throughout their lifecycle, allowing greenhouse and indoor growers to realize excellent production levels per plant. It also affords extra physical stability for top-heavy plants and additional protection from algae and root pests thanks to its UV-resistant cover. Recommended for larger, long term crops with extensive roots like peppers, tomatoes, or cucumbers. Grodan Expert is the slab that drains the fastest because of its vertical fibers. By far the most popular slab for the hydroponic hobbyist market. In addition, the top layer is thicker, which stays wetter, while the bottom layer stays drier. In effect it defies gravity, allowing more even distribution of moisture throughout the slab.

Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Grodan comes in graduated sizes. Seedlings started in cubes are easily transferred to blocks and then onto slabs, if desired. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums.
