CO2 Systems: Regulators, Controllers & Monitors | Planet ...

Plants use the carbon dioxide (CO2) that occurs naturally in our atmosphere, along with sunlight, to make the energy it takes for growth. Plants will exhaust the level of atmospheric CO2 — 300 parts per million (ppm) — as they grow in enclosed spaces (when CO2 levels fall to 200 ppm, plant growth ceases). Increasing the level of carbon dioxide in your grow room or hydroponics setup can increase …
