Air circulation is critical for healthy plants, making the installation of an exhaust fan a greenhouse must have.
These intake shutters are part of the exhaust fans for all of greenhouses. The intake shutters measure 24″ x 24″ and control air ventilation, hence giving you one of the most important cooling elements required for greenhouse growing.
How Intake Shutters Work
You will require electricity for these motorized intake shutters to operate. Place your intake shutters opposite to the exhaust fan as low to the ground as possible because this allows cooler air at ground level to enter your greenhouse. Place your exhaust fan as high up in the opposite gable end as possible. As a result, the warm air rises and the exhaust fan continuously sucks out the warm air. The intake shutters bring in cooler air because they are placed closer to ground level. Normally, intake shutters are placed on either side of your front door.
Avoid harmful insects entering your greenhouse. Insect screens ensure that harmful insects and debris will not enter your greenhouse.
