Over the last decade growers and researchers alike have seen that water management can steer the development and growth of the plant. For example, by controlling the starting and stopping times of irrigation the plant can be steered towards more generative or vegetative production. Although growers can control when they water, in most cases it is difficult to see precisely when watering starts and stops and the effect it has, for example, on the slab EC and water content without looking back over data collected and embedded somewhere in the pc. Therefore easy to access advice and a picture of what is actually happening in the greenhouse is welcomed by growers trying to optimise their production. In line with the technology available and the research coming to light Grodan, which manufacturers rock-wool slabs realised that the success of the slab lies in the way it is watered.
