The V-Slab is designed specifically for vertical systems with step by step instructions on the wrapping. The slabs are high density which spreads the water and nutrients from side to side in the slab. V-Slab has great water distribution; specifically there is only a 5% difference in water content between the top and bottom of the slab, where competing brands show a 17% difference.
