One thing that we know is true - it is easier to add heat than take it away. Given that many areas are set to endure a heat wave, here are some quick thoughts on cooling your greenhouse. If you have a glass greenhouse in full sun, you are going to need a few options to keep it cool.
- Shade cloth is the first and easiest recommendation. We often recommend a company that has a full complement of shade cloth options: https://shadyplains.com/
- Plant a tree to provide some natural shade cover. If you can find a sturdy variety that gains leaves in May and drops leaves for winter, you would have the best of both worlds because the greenhouse will get more light in winter when it needs it.
- Exhaust fan systems and evaporative coolers are mechanical options that move hot air out of the greenhouse.
- Many of our customers spray down the greenhouse floor every morning to keep it cool too.
- Move your plants to ground level where it is naturally cooler.
- Prop the door open and make sure you have circulating fans moving the hot air
- If you know that a certain wall is going to take most of the heat, think about a shade trellis. Vines that trail up the exterior of the greenhouse are a great way to create shade.
- Whitewash paint is a very old technique that some customers use to prevent too much sun exposure hitting their plants.
- Lastly, a ceiling fan is an interesting option as you can place it directly below the roof vents, reverse the spin direction and pull hot air up and out of the greenhouse.
