Slabs are the premium product for vegetable cropping. They are available wrapped in UV resistant polyethylene sleeves for ease of use. The special structure provides a uniform environment allowing plant roots to rapidly explore all the available growing volume for a quick start. Water and nutrient distribution is also more uniform and provides a larger effective rooting volume than previously possible. Slabs come in 36" lengths and 3" heights and have two different sizes of widths. The 6" slab is suitable for crops that do not tend to require a very large root capacity. The 8" slab is mainly for extremely vigorous crops such as cucumbers that require a strong and stable base and a large root capacity. The Slabs are easy to use just cut holes in the top of the slab set your cubes on top and cut a few slits in the bottom of the slab's plastic for drainage
