For the most accurate function, Use a PPM controller like the Sentinel CHHC-4i or CPPM-4i to measure and maintain the exact amount of CO2 in the growing environment at all times.
The most common recommendation for PPM levels for rapid plant growth is between 1000 and 1500 PPM. The plants will benefit most by maintaining the CO2 level within this range during daylight hours.
