Greenhouses need to be designed to not only capture solar technology but also adequately ventilate excess heat if temperatures get too hot.
You should always make sure you have adequate vents in the roof of your greenhouse as heat rises and you want that heat to flee.
Greenhouse roof vents work really well as they are located where hot air gathers naturally at the peak of the roof.
If vents in the roof are not possible, ensure that you at least have a windowpane to two you can open.
Ideally you need to have cross ventilation therefore two windows upon two sides of the greenhouse work best.
However you shouldn’t leave the vents or windows open at nighttime as you’ll lose any heat gain and cool your greenhouse too much.
And that means you close the vents or windows during the night and what happens another morning: you forget! Now your greenhouse overheats and if you’re unlucky, you lose some plants.
Or you forget to close the vents at nighttime and your plant life suffer if the night is too cool.
If just recently you, one of your buddies or relative had any kind of experience with Greenhouse Auto Vent, don’t think twice to share your viewpoint in remarks.
