Did you know that proper ventilation is one of the most important factors to consider when you select a greenhouse for backyard gardening? The job of a greenhouse is to warm the air inside the greenhouse and prevent it from escaping, thus extending the life of your garden to three, and sometimes four, seasons. Without proper ventilation, though, a hobby greenhouse can become too humid or too hot for your plants, flowers, and vegetables. Good ventilation is key, and this usually means circulation of new air every three to four minutes inside during the summer. Without this circulation in the summertime, the greenhouse temperature will rise and can damage tender plants. Fans contribute to mixing the air along with vents in the greenhouse roof and side walls. In the spring and fall, these vents can usually cool the greenhouse without the need for circulating fans, which keeps your electric bill lower. During the winter, opening and closing the greenhouse vents will allow plants to grow accustomed to the colder weather without freezing.
With just a little practice, properly ventilating your hobby greenhouse will become a breeze, and you’ll benefit with a bountiful harvest.
I am one of those people Jon. I only recently purchased my first greenhouse and after constructing it stood back and realised I had absolutely no idea what I was doing. This post, at least, leaves me slightly more clued up. Appreciated!
It never ceases to amaze me at how many people don’t realize how important ventilation is to a proper greenhouse setup. Thanks for the informative post.
