Greenhouse Auto Vent

Greenhouses have to be designed to not only capture solar technology but also adequately ventilate excess heat if temperatures get too hot.

You should always be 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 because they are located where hot air gathers naturally at the peak of the roof.

If vents in the roof are not possible, be sure to at least have a windowpane to two you may open.

Ideally you want to have cross ventilation so two windows upon two sides of the greenhouse work greatest.

However you should not leave the vents or windows open at nighttime as you’ll lose any kind of heat gain and cool your greenhouse too much.

So you close the vents or windows at night and what happens another 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 time is too cool.
