Why is Cooling Down Greenhouse Important?
The key to keeping your greenhouse cool and comfortable is to create a balance between the temperature outside and the temperature inside. During hot summer days, it’s important to keep the greenhouse at a much lower temperature than what’s outside in order to prevent plants from getting too hot and drying out.
If you want your greenhouse to remain productive all year round, cooling it down is essential.
Is It Possible to Cool a Greenhouse Without Electricity?
Yes! There are a few ways to cool down your greenhouse without electricity. Some of these strategies work best if you have an outdoor garden, while others can be used even in the most confined indoor spaces.
Here are some of our favorite suggestions on how to keep your greenhouse cool without electricity. You can use one or more of these techniques to get the job done.
- Shade Cloth
- Watering Can/Hose
- Plant Misters/Sprayers
10 Tips on How to Cool a Greenhouse Without Electricity
1. Shade Cloth
One of the most basic tactics for cooling down your greenhouse without electricity is to use shade cloth. Shade cloths provide a structure that’s designed to block out some of the sun’s rays and prevent them from hitting your plants directly.
2. Watering Can or Hose
Watering your plants can be an effective way to cool down a greenhouse without relying on electricity. Water helps to absorb and regulate heat, which means that watering your plants regularly can help to keep the temperature in check.
3. Plant Misters/Sprayers
Misting your plants is another way to lower the temperature inside your greenhouse without needing any additional energy source. You can use a watering can to mist your plants, or you could invest in a mister or sprayer for larger greenhouses.
Fans are typically electric-powered devices that circulate the air inside space and help keep it cool. However, if you’re looking for an alternative way to cool down your greenhouse without electricity, you can try using a fan powered by solar energy.
This type of fan uses solar panels to convert the sun’s rays into electricity, which is then used to power the fan for an eco-friendly cooling system.
5. Lower Humidity
Humidity has the potential to make your greenhouse feel even hotter than it already is. To cool down your greenhouse without electricity, you should ensure that you’re keeping the humidity levels as low as possible by using a dehumidifier or opening windows and doors to let cool air in.
Ventilation is essential for any greenhouse and can make a huge difference when it comes to temperature control. Open windows, doors, and vents to let cool air in and hot air out to help regulate the temperature inside your greenhouse naturally.
Another way to keep a greenhouse at a comfortable temperature without electricity is to use insulation. You can install insulation such as foam boards or bubble wrap around the walls of your greenhouse to help create an insulated barrier that will keep the temperature inside cool.
8. Plant Selection
Choosing the right plants for your greenhouse can also go a long way in helping you stay cool without electricity. Plants such as ferns, African violets, and wax begonias are all great options for cooler climates because they don’t require a lot of heat to thrive.
9. Colorful Paint
Adding bright or light-colored paint to the walls of your greenhouse can help to reflect sunlight away from the plants and keep them cooler during hot days. You should avoid using dark colors that absorb heat, as this could lead to an even hotter environment.
10. Plant Coverings
Covering your plants with light-colored material such as cloth or sheet can also help to keep their temperatures down throughout the day and prevent them from getting too hot. You should be sure to remove the coverings at night so that the plants get enough light for photosynthesis.
By following these steps, you can keep your greenhouse cool without needing to rely on electricity. While some of these methods may require a bit of time and effort, they are all great ways to maintain a comfortable temperature in your greenhouse without having to pay for any additional energy costs.
8 Maintenance Tips
- Position Your Greenhouse Strategically: Place the greenhouse in an area that is shaded from direct sunlight, preferably on the east or north side of a building or fence. The position of the greenhouse can make a huge difference in temperature and ventilation.
- Block Direct Sunlight. To reduce the heat buildup inside the greenhouse, use shade cloths to block direct sunlight entering your structure during periods of intense sunshine. Keep in mind that this will also reduce light levels and plant growth, so you’ll want to be careful not to block off too much light.
- Vents and Fans: Open the roof vents, door vents, or side wall vents when temperatures rise during the day to allow hot air to escape from your greenhouse and close them back up at night when it gets cooler outside. If you don’t have any electric-powered fans, you can use a hand-held fan to help circulate the air in your greenhouse.
- Plant Strategically: Place taller, sun-loving plants around the perimeter of your greenhouse so that they provide shade for more sensitive species inside. You can also line the interior walls with a reflective material such as aluminum foil to reduce heat buildup inside the structure.
- Manually Evaporate Water: Fill shallow bowls or trays with water and place them in your greenhouse to help reduce the air temperature by manually evaporating it. You can also consider installing misters or fogging systems if you have access to a reliable water source.
- Open Windows and Doors at Night: When temperatures drop outside of your greenhouse at night, open the doors and windows to allow cool air to circulate. If you have an automated system in place for this, make sure it’s functioning correctly; otherwise, you can manually do this yourself.
- Insulate the Walls and Roof: Installing insulation on the walls and roof of your greenhouse can help to reduce heat gain from the outside and retain cooler air inside. You’ll want to make sure that your insulation is secured tightly in place, so it doesn’t come loose or become damaged over time.
- Monitor Temperature Levels in the Greenhouse: Keeping tabs on the temperature inside your greenhouse is key for knowing when it’s time to take action in order to cool down the structure.
You can install a thermometer inside your greenhouse or purchase an app-enabled device that will alert you when temperatures rise too high. By monitoring temperature levels and making adjustments as needed, you can keep your plants healthy and happy.
By following these 8 tips, you can keep your plants thriving in a cool and well-ventilated greenhouse without needing to rely on electricity. With some creativity and careful planning, you can create the perfect environment for your green-thumbed creations.
How Much Will It Cost?
The cost of cooling a greenhouse without electricity depends on the type of materials and equipment you use. You can purchase shade cloths, insulation, misters, fans, and app-enabled temperature monitors for anywhere between $50-$200, depending on your budget and needs. Additionally, it’s always a good idea to check with your local building supply store or gardening center for discounts and sales before you purchase supplies.
All in all, cooling a greenhouse without electricity is not as hard as it may seem. With just an understanding of the benefits and disadvantages of your methods, you can maximize the effectiveness of your approach.
As long as you focus on keeping the greenhouse from getting too hot, you should have great success in temperatures that aren’t hazardous to your greenhouse plants.
However, if nothing else works, it is best to think about investing in a cooling system that uses less electricity than the average air conditioner. In this way, you can still keep your plant life cool and get more out of each day in terms of efficiency and cost.
