Venting Intake: 48” aluminum high velocity shutter vent (Specifically: Dayton 48” Backdraft Damper model # 4FZJ2)

Motorized Shutter Kit for 12-60 in. shutters, #1260 Motor, with cord

This shows the final set-up for my outside air venting system. If you look in the middle on the lower side of the shutter, you will notice an electric motor. This was connected to a thermostat that would engage the motor when the temperature reached about 85F. While there was no fan to assist the air coming in when the thermostat was engaged there were two vents opening at the same time as the upper vent and the exhaust fan would come on at the same time. This created a flow through of air that allowed for efficient cooling with minimal loss of CO2 that was being added to the environment below the pumpkin leaf canopy.
