The mechanical ventilation method used for greenhouse cooling can help improve the air circulation faster. You have to get an exhaust fan to pull the heat rather than just get a regular fan from the store which may actually blow hot air inside your greenhouse. If you are still using the natural ventilation method, outside factors can destroy the cooling you’re looking for without buying an exhaust fan. Computers and thermostats can be used with this method so you can adjust the air flow and temperature also. The exhaust fans must be in the correct location for the right air flow so make sure to get the cubic feet per minute rating of the fan.
