Introduction ============ The FLORATek 4 is a powerful hydroponics controller designed to monitor, track, and control the pH and nutrient levels in your hydroponics system. It represents the culmination of knowledge and experience that we have gained from developing the FLORATek 3 and 3X systems. Users familiar with those systems will find much of the same DNA in the FLORATek 4. This is intentional - when developing a new product, we first analyze the best traits of our previous products and carry them over into subsequent designs. Our most important resource when developing a new product, however, is customer feedback. The majority of the new features you will find in this new control are features that have been requested by previous customers just like you. Key Improvements ---------------- We went back to the drawing board to develop our own EC and pH measuring circuits and firmware. The hydroponics environment can be notoriously difficult to get both accurate and reliable sensor measurements, but we believe this new system sets a new standard not only within our own product line, but across the industry. About This Manual ----------------- This manual will guide you through the setup, configuration, calibration, and operation of your FLORATek 4 system. Please read through the relevant sections carefully before using your controller.
