A right environment is the fundamental prerequisite for temperature control: we have to inject heat (i.e., energy) in the system in order to increase its temperature. Large systems need great amounts of energy. Arbitrary large systems need arbitrary amounts of energy. Simply put, I just can afford heating the cartoon box shown in Picture 2.
A typical nutrient quality control system and water chiller are shown below. Handheld or desktop meters are used for monitoring temperature, humidity and water quality. Electrical timers are used for switching devices such as grow lights, pumps, fans and other devices that run on schedule.
