Pro-Leaf Co2 Controller PPM-B1
The Pro-Leaf Co2 Controller PPM-B1 is a digital CO2 controller for grow rooms. It reads the carbon dioxide level in the room and runs a CO2 source to hold that level at a target the grower sets, so supplementary CO2 goes in when the room drops below the target and stops once it gets there. It doses against a real reading. It does not run a bottle on a timer and hope the level is right. A built-in photocell lets the controller follow the lights, so dosing can be kept to the lights-on period and no gas is spent while the plants are in the dark and cannot use it.
The control loop starts at a remote sensor on its own lead. That lets the sensor sit out in the growing space while the controller is mounted wherever it is easy to read and reach. The recommended placement for the sensor is the middle of the room, at about 1.5 m (5 ft) from the floor. The controller compares each reading with the set-point and acts on the difference, and an adjustable deadband decides how far the level may drift before it does. A deadband is the window around the target where the controller deliberately does nothing. A wider window means fewer on and off cycles for the solenoid or generator, and a narrower one holds the room more tightly. The sensor is self-calibrating, and the controller keeps a record of the highest and lowest CO2 readings it has seen, so it is easy to check how far the room swung between visits.
It works with the two common ways of adding CO2: a bottled system run through a regulator and solenoid valve, or an LPG or propane CO2 generator. The photocell gives three operating modes: day, night and continuous. Day mode is the natural starting point because it ties dosing to the hours when the lights are on and the plants are actively drawing CO2. The night and continuous modes are there for setups that need the controller working outside that window. Plan on having the sensor recalibrated once a year, which is the recommended interval even with its self-calibration. After any change to the room, such as new extraction or a different lights-on schedule, check the maximum and minimum record to see whether the target is still being held.
Set your target CO2 level and let the controller hold the room there!
