Cabinet is monitored and controlled by 2 smart plugs controlling the timing for the lights and an Arduin controlling the wind and vent fans, monitoring the temperature, humidity, CO2 and TVoC's (Smell imo) as well as the soil moisture in both pots. The "wind" fans turn on for a random amount of time between 1-10 minutes every 1-10 minutes and has 2 different speeds controlled by relays sending 5v or 12v. I'll wire up the PWM control eventually but it works well as it is for the time being. The vent fans turn on if the temperature, humidity or TVoC's get too high or if the CO2 gets too low. The output is monitored via serial on a laptop running as a server in the cabinet which has been handy for keeping the cabinet warm in the winter, this is then sent to Thingspeak so I can monitor it all remotely. I plan on adding a further 4 fans at the back, 2 on the right and 2 cantered so I can have more airflow.
