Greenhouses need to be designed to not only capture solar energy 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 escape.

Greenhouse roof vents work really well because 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 windowpane to two you can open.

Ideally you need to have cross ventilation so two windows on 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.

So you close the vents or windows during the night and what occurs 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 and your plants suffer if the night is too cool.
