Frequently Asked Questions
Why does CO2 supplementation help plant growth?
Photosynthesis uses CO2 directly as a raw material, and ambient outdoor air, around 420 ppm, is often below the level at which many crops photosynthesize fastest, so raising CO2 in an enclosed grow space can increase growth rates.
What CO2 level is typically targeted in a grow room?
A target range of roughly 1,200 to 1,500 ppm is commonly cited for many crops grown under supplemented CO2, well above the ambient outdoor level but below levels considered unsafe for people working in the space.
Is high CO2 safe for people working in the grow room?
Very high sustained CO2 levels can be unsafe for people, so grow rooms using CO2 supplementation need proper ventilation, monitoring, and safety procedures, and should never be treated purely as a plant-only consideration.
