This is our first winter with our small green house. At night, the temperature will go down to the outside temperature (We haven’t added heat yet). But during a sunny day, it can be 120F inside! Even when it is only 10F outside. As we are getting ready to start our seeds, I built a temp/pressure/humidity/Lux sensor to log the Greenhouse climate. We have manual ceiling vents, but we decided to add an automated gable fan and a fresh air vent. Since most small vents are for exhausting air, I designed / 3D printed an input louver vent.
The 3D print files are located:

We used the following:
* 12 inch thermostat controlled louver fan ( https://amzn.to/3kmiQQM )
* 9’x12′ Greenhouse ( https://amzn.to/36paYqy , https://www.farmtek.com/farm/supplies/ProductDisplay?mfPartNumber=104605 )
* Steel base ( https://www.farmtek.com/farm/supplies/ProductDisplay?mfPartNumber=104606 )
