Precision control of all the variables in your grow environment can greatly maximize yield. The microprocessor based Plant Pro hydroponics controller from Solatel offers exact electronic timing for lighting, irrigation, ventilation, and CO2 dispensing. Accurate measurements from environmental sensors allow Plant Pro to maintain the perfect environment for your plants to thrive in. Solatel’s solid state integrated environmental sensors feature much higher accuracy than the usual mechanical sensors found in many grow-room environments. Environmental sensors come with flexible 10’ cables that allow for optimum placement of sensors in the grow space. This provides for better accuracy and, if desired, allows the control unit to be located outside the grow-room environment for easy monitoring and adjustment. During operation, the large, easy-to-read digital display allows monitoring of timed functions and sensor thresholds as well as the levels of any attached environmental sensors. Sensor levels can be displayed individually or can be set to rotate through all (pausing at each one for a few seconds), so the status of the entire system can be seen at a glance. Purchase with the CO2 sensor or add one to the unit, then set your PPM, and let the Plant Pro control it . Each unit comes with flood, temperature, and humidity sensors.
