The Slab method is most commonly used by commercial farmers to grow larger, high productivity plants (tomatoes or cucumbers) and large scale flower production. Drop irrigation is the preferred method to feed plants at regular intervals direct from Holland, this stone wool is superior to competitive products!

The fibre structure ensures optimum exchange within the slab and accurate control of moisture content and nutrition.


Any excess water runs off quickly and efficiently, so that the roots stay active and the horizontal fibre direction facilitates the control of both water content and EC.
