Greenhouses have to be designed to not merely capture solar technology but also adequately ventilate excess heat if temps get too hot.
You should always make sure you have sufficient 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 heat gathers naturally at the peak of the roof.
If vents in the roof aren’t possible, be sure to at least have a windows to two you can open.
Ideally you wish to have cross ventilation so two windows on two sides of the greenhouse work greatest.
However you shouldn’t leave the vents or windows open at nighttime as you’ll lose any heat gain and cool your greenhouse an excessive amount of.
Which means you close the vents or windows at night and what happens the next morning: you forget! Today your greenhouse overheats and if you’re unlucky, you lose some plants.
Or you forget to close the vents at nighttime as well as your vegetation suffer if the night is too cool.
