I got a bottle of co2 with a releas valve,and a cd to calculate the amount of time im to open the valve for. My lights are on their own "cooling system",(cool tubes)the air is taken from outside the grow room and exhausted outside so it doesnt disturb any of the air flow in the room,then ive an in take fan,and another exhaust fan,and circulating fans,so when i open the bottel(ill be getting a solenoid valve shortly) should i turn off the exhaust fan and intake fan and just leave the circulating fans for maybe an hour or so??or somthing along those lines???
