The CO2 Regulator fits onto your CO2 cylinder, managing the quantity of CO2 that is emitted and delivered to plants.
The level of CO2 required will depend on the total area of the grow room or tent and the level of extraction that is in place - that's why you'll also need a separate Controller Unit to control dosage levels. The controller connects to the CO2 Regulator feeding it information based on user-defined settings.
CO2 is a naturally occurring gas that plays an essential role in the process of photosynthesis. Typically, the atmosphere around us has CO2 present in concentrations of around 360 parts per million (ppm).
Plants can use up the ambient level of CO2 within an hour, and when levels drop below 200ppm, growth will quickly start to stall.
This issue can be addressed by equipping your grow room with an adequate extraction system; however, plants can make use of more CO2 than is generally present in the atmosphere, and supplementing with additional CO2, when used correctly, has numerous benefits, making plants more tolerant to higher temperatures, triggering amplified growth rates and delivering improved harvests, both in terms of quality and quantity.
Optimal levels of CO2 are between 1000ppm and 1200ppm; levels higher than this can be detrimental to supplementation and levels above 2000ppm actually become toxic to your plants.
At 4000ppm to 5000ppm levels become toxic to humans!
