It takes its orders from the \u003cstrong\u003ePro-Leaf CO2 Controller\u003c\/strong\u003e, opening only until the room reaches the pre-set ppm figure or the set time elapses, which keeps levels where you want them without ever tipping into the danger zone. Get it right and you get faster growth, larger plants and a noticeably better harvest.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolenoid control\u003c\/strong\u003e opens and closes the valve automatically, with no manual input.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolds the optimal 1000-1200ppm\u003c\/strong\u003e band when paired with the Pro-Leaf CO2 Controller.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in safety logic\u003c\/strong\u003e - the valve shuts at the pre-set limit or time, preventing toxic levels building in the room.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigher heat tolerance\u003c\/strong\u003e for your plants, which is useful in summer when temperatures run away.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits standard CO2 cylinders\u003c\/strong\u003e, a simple bolt-on for a sealed or semi-sealed room.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy Does Growth Stall in a Sealed Room?\u003c\/h3\u003e\u003cp\u003eAir sits at roughly \u003cstrong\u003e360ppm\u003c\/strong\u003e of CO2, and a healthy canopy can strip that out within an hour. Once levels drop below \u003cstrong\u003e200ppm\u003c\/strong\u003e growth slows badly whatever your light, feed or airflow - photosynthesis runs out of raw material, and you get slow growth and low yields you cannot explain. Extraction helps, but plants perform better on more CO2 than the atmosphere provides. Above \u003cstrong\u003e2000ppm\u003c\/strong\u003e CO2 turns toxic to plants, and \u003cstrong\u003e4000-5000ppm\u003c\/strong\u003e is dangerous to people, which is why controlled dosing beats guesswork.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cp\u003eFit the regulator to a charged CO2 cylinder and connect it to the Pro-Leaf CO2 Controller. Set your target between \u003cstrong\u003e1000ppm and 1200ppm\u003c\/strong\u003e and position the controller's sensor at canopy height, away from the gas outlet. Only enrich during the lights-on period, and time extraction so you are not venting the CO2 you have just paid for. Never enter a room that is actively dosing at high concentration, and check the cylinder pressure regularly so the system is not running empty mid-cycle.\u003c\/p\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e CO2 regulator with solenoid valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e CO2 gas cylinders\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl:\u003c\/strong\u003e Operates from the Pro-Leaf CO2 Controller (sold separately)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimal target range:\u003c\/strong\u003e 1000-1200ppm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmbient CO2 reference:\u003c\/strong\u003e Around 360ppm; growth slows below 200ppm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety limits:\u003c\/strong\u003e Toxic to plants at 2000ppm; 4000-5000ppm dangerous to humans\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Pro-Leaf","offers":[{"title":"Default Title","offer_id":53445688033546,"sku":null,"price":75.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/86498-ProLeafCO2Regulator.jpg?v=1785324969","url":"https:\/\/hydrocropshop.co.uk\/products\/pro-leaf-co2-regulator","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
