How to use: Use a timer like the Sentinel DRT-1a to turn the CO2 solenoid On and Off at regular intervals. Use an environmental controller like the Sentinel EVC-1 or DEC-4 to activate the CO2 solenoid only during the day and to coordinate the CO2 operation with the ventilation control. For the most accurate function, use a PPM controller like the Sentinel CHHC-4 or CPPM-4 to measure and maintain the exact amount of CO2 in the growing environment at all times. Use controller like the EVC01 or EVC-2 to activate the CO2 solenoid only during the day and to coordinate the CO2 use with ventilation control. Use a Part-per-million CO2 controller like the CTC-1. Measuring the exact amount of CO2. In PPM, provides the most accurate method of control. 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. Free Shipping rates apply to the lower 48 contiguous states.
