The optimal concentration of CO2<\/sub> for most plant species is around 1000 PPM. Here, we discuss the use of mass flow control to regulate CO2<\/sub> levels and improve indoor growing processes.\n

Using CO2<\/sub> gas to boost indoor plant yields<\/h2>\nMonitoring and maintaining an indoor CO2<\/sub> concentration of around 1,000 PPM will maximize the yields of most crops by up to 50%<\/a>. However, this must be precisely controlled, as concentrations of CO2 <\/sub>at 2,000-5,000 PPM<\/a> can cause headaches and nausea and at 50,000 PPM can lead to loss of consciousness or even death. Therefore, if CO2<\/sub> is supplemented, precautions must be taken to continuously and accurately raise, lower, and monitor CO2<\/sub> levels.\n\nThe main components to control CO2<\/sub> levels in indoors hydroponics systems include the following:\n\n \n\nCO2<\/sub> is released from the gas source as needed based on set points from the CO2<\/sub> monitor while amounts of total CO2<\/sub> gas and their flow rates are controlled using flow meters and controllers. For optimal CO2<\/sub> control, Alicat\u2019s M<\/a> and MC-Series<\/a> devices offer gas control and measurement to \u00b10.5% of reading or \u00b10.05% of full scale, a control range of 0.01-100% (10,000:1 turndown), and a flow range up to 5,000 SLPM.\n\nTo eliminate separate flow controllers for inflowing and for outflowing CO2<\/sub>, Alicat\u2019s MCD-Series<\/a> of bidirectional gas mass flow controllers provide a process solution where CO2<\/sub> can be simultaneously added and removed.\n

Using CO2<\/sub> gas as a natural pesticide<\/h2>\nAnother less common application for CO2<\/sub> in indoor hydroponic farming systems is as a food-safe natural pesticide. At concentrations of 40% or higher<\/a>, 400,000 PPM, CO2<\/sub> can kill all different types of bugs within 7-15 days and as quickly as 60-120 hours for some species. When used indoors as a fumigant, CO2<\/sub> reduces levels of oxygen, thus bugs die from asphyxiation.\n\nTo add the CO2<\/sub> for fumigation, flow controllers and pumps are used, thus reducing the air\u2019s concentration of oxygen. After the process is complete, pumps and flow controllers remove CO2<\/sub> until the CO2<\/sub> monitor returns back to an optimal concentration for plant growth around 1,000 PPM.\n

Pairing Alicat mass flow controllers with CO2<\/sub> monitors<\/h2>\nAlicat\u2019s mass flow controllers offer multiple solutions for communicating with CO2<\/sub> monitors to fully automate the previous processes. Alicat\u2019s devices can work with PLCs, allowing for pairing with CO2<\/sub> monitors, providing a wide range of customizable control possibilities. For example, to reduce the chance of accidental human exposure to dangerous levels of CO2<\/sub>, when connected to a PLC, an alarm<\/a> output can be set to trigger at different concentrations of CO2<\/sub>, notifying a central system when the process falls outside of tolerances, shutting off (or turning on) the Alicat mass flow controllers.\n
