The added demands for water in these conditions is surprising. Fortunately, provided there is water available, the system copes wonderfully well because it is at this stage that the deficiencies of hand watering or even programmed watering really show up. But when you start to feel that you are there to serve your system rather than it being the other way around, it’s time to consider upgrading to a pressurised system. So we introduce you to yet another ingenious innovation by Jim Fah – the Smart-pump Feeding System. There are several ways nutrient solution can be delivered to the growing modules. It can be fed from a small pressure-switch pump as shown in diagrams A and B page 28 together with different options for nutrient supply and additional dosing of other chemicals such as pH correction fluids.
