SPARC CO2 Grow Room Regulator + Flowmeter w/ 120V Solenoid


: In stock


High-Quality CO2 Flowmeter

SPARC's CO2 grow room regulator + flowmeter is designed to manage the flow of carbon dioxide. This flowmeter is great for indoor gardening, grow rooms, and greenhouses to enhance carbon dioxide in the growing environment. CO2 is a very important nutrient required for plants to grow. If everything is being done correctly and you have a finely tuned system, then adding carbon dioxide can increase your yields substantially. Simply increasing CO2 levels in your plants can significantly improve plant growth without having to change the way you grow.

Durable, Reliable Components

SPARC's precision-made CO2 flowmeter is crafted entirely from brass. These long-lasting, brass components will function for many years without rusting or malfunctioning. This grow room CO2 flowmeter comes with a 10-foot long air hose and a 120V outlet power cord. SPARC's carbon dioxide flowmeter can handle up to 4000 PSI and release between 0.5 and 15 cubic feet per hour of gas.

Essential Solenoid Valve

With SPARC's 120V solenoid valve, you can simply set it on a timer or another control device, which allows you to release CO2 in intervals. This valve is essential in speeding up growth rates and yields by up to 40%. The precision flow gauge can release between 1/2 and 15 SCFH of CO2 per hour (standard cubic feet per hour). This allows customers to maintain ideal CO2 levels for optimum growth.
