In a sealed or tightly controlled room, plants under strong lighting draw that down within hours of lights-on, and once it falls, photosynthesis and growth slow however well the plants are fed and watered. Topping the room back up, commonly to around \u003cstrong\u003e1,000–1,200ppm\u003c\/strong\u003e during the lights-on period, lets plants make full use of the light and copes better with warm conditions. Too much CO2, though, is wasted gas and a hazard to anyone working in the room. A controller that measures the air and releases CO2 only when the level falls below target keeps enrichment accurate, economical and safe.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount the controller\u003c\/strong\u003e on a wall where the screen is easy to read, out of direct spray and drips\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlace the sensor\u003c\/strong\u003e at canopy height on its 4.5m cable, away from the CO2 outlet and the extraction inlet, where the photocell can see the lights\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnect your CO2 source\u003c\/strong\u003e – such as the solenoid of a CO2 release kit – to the controller output (maximum \u003cstrong\u003e5A at 240V\u003c\/strong\u003e)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet the target and zone\u003c\/strong\u003e in plant mode, for example a \u003cstrong\u003e1,200ppm\u003c\/strong\u003e target; the controller releases CO2 whenever the room drops below the zone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBottled CO2:\u003c\/strong\u003e use a vapour-release cylinder, check every joint with soapy water and run the release tube above the canopy – CO2 is heavier than air and sinks onto the plants\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePause extraction\u003c\/strong\u003e while enriching, or the CO2 goes straight out of the room; switch to human mode before working inside\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e 2-in-1 CO2 monitor and controller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e large LCD – live CO2 ppm, target (centre) and zone settings, one-week CO2 log\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModes:\u003c\/strong\u003e plant mode (raises CO2 by switching a CO2 source); human mode (lowers CO2 by switching extraction)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDay\/night control:\u003c\/strong\u003e photocell on the sensor – no CO2 release in the dark period\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor:\u003c\/strong\u003e remote, on a 4.5m cable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput:\u003c\/strong\u003e 100–240V AC, 50–60Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum load:\u003c\/strong\u003e 5A at 240V \/ 10A at 120V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e wall mountable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelease kit (kit option):\u003c\/strong\u003e GasArc CO2 cylinder regulator with twin gauges, wired CO2 solenoid valve, 10m release tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas supply (kit option):\u003c\/strong\u003e bottled CO2, vapour-release cylinders only – cylinder not included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cdiv class=\"hcs-faq\"\u003e\n\u003cdetails style=\"border:1px solid #e6e6e6;border-radius:8px;padding:12px 16px;margin:0 0 8px;\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;\"\u003eIs a CO2 cylinder included?\u003c\/summary\u003e\u003cp style=\"margin:10px 0 0;\"\u003eNo. The kit option includes the GasArc regulator, solenoid valve and 10m release tube; it fits a vapour-release CO2 cylinder (not a liquid-withdrawal, dip-tube cylinder), which you buy or rent separately.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #e6e6e6;border-radius:8px;padding:12px 16px;margin:0 0 8px;\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;\"\u003eWill it release CO2 at night?\u003c\/summary\u003e\u003cp style=\"margin:10px 0 0;\"\u003eNo. The photocell on the sensor tells the controller when the lights are off, and it holds CO2 release until the lights come back on.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #e6e6e6;border-radius:8px;padding:12px 16px;margin:0 0 8px;\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;\"\u003eWhat does human mode do?\u003c\/summary\u003e\u003cp style=\"margin:10px 0 0;\"\u003eInstead of adding CO2, it switches the output to run your extraction and bring the level down, so the room is safer to work in.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #e6e6e6;border-radius:8px;padding:12px 16px;margin:0 0 8px;\"\u003e\u003csummary style=\"cursor:pointer;font-weight:600;\"\u003eCan I use it with the CO2 equipment I already have?\u003c\/summary\u003e\u003cp style=\"margin:10px 0 0;\"\u003eYes.
