you want that heat to escape.<\/p>\nGreenhouses have to be designed to not merely capture solar energy but also adequately ventilate extra heat if temperature ranges get too hot.<\/p>\n
You should always be sure you have sufficient vents in the roof of your greenhouse as heat rises and you want that heat to escape.<\/p>\n
Greenhouse roof vents function really well as they are located where hot air gathers naturally at the peak of the roof.<\/p>\n
If vents in the roof are not possible, be sure to at least have a home window to two you can open.<\/p>\n
Ideally you wish to have cross ventilation therefore two windows on two sides of the greenhouse work best.<\/p>\n
However you shouldn’t leave the vents or windows open at nighttime as you\u2019ll lose any heat gain and cool your greenhouse an excessive amount of.<\/p>\n
Which means you close the vents or windows at night and what occurs the next morning: you forget! At this point your greenhouse overheats and if you\u2019re unlucky, you lose some plants.<\/p>\n
Or you forget to close the vents at nighttime and your plants suffer if the night is too cool.<\/p>\n
