Have you ever wondered how to keep your greenhouse cool? If your greenhouse is too hot, it can damage your plants, causing them to wilt and die. One of the best ways to keep a greenhouse cool is to maximize shade, ventilation, and airflow.
However, the coolness of your greenhouse depends on several factors, such as your location, climate, the type of plants you’re growing, and more.
What Temperature Should You Keep Your Greenhouse?
Greenhouses that exceed over 90 degrees F is already too hot for your plants. If your greenhouse is too hot, your plants may wilt, dry out, or stop producing leaves and fruits. For your plants to grow and produce fruits or vegetables, they need to be at their ideal temperature.
Generally, the temperature of your greenhouse should be between 80- and 85-degrees F. However, some plants thrive best in temperatures lower than that, so make sure to know the ideal growing conditions of your plants.
How Do You Cool a Greenhouse in High Humidity?
There several ways to cool a greenhouse during high humidity. Here are three of the most cost-effective ways to do so:
To effectively lower greenhouse temperature, you need to provide plants with a good inflow and outflow of air. You can place roof vents and side vents. Additionally, your greenhouse’s door should also create a movement of air to cool your plants.
Placing roof vents to one-fifth of floor space should give your greenhouse a complete air change every two to three minutes. But if roof vents are out of the budget, opening the side vents and doors is enough.
Proper shading can help keep your greenhouse cool. However, adding shades to your greenhouse is tricky because plants need sunlight to grow. While shading can help cool down a greenhouse, you also have to allow enough sunlight inside.
One of the effective shading techniques is to use shade paints. Shade paints are a cost-effective way to shield your plants from the sunlight. As summer rolls in, you can add more coats of paint and brush it off as cool-season begins. However, shade paint may not be the best option for all greenhouses. If you can’t paint your walls, you can opt for netting or blinds.
Dampening your greenhouse is the cheapest way to cool down your greenhouse. In fact, it’s practically free – all you need is water. You can dampen your greenhouse by wetting hard surfaces. As the water evaporates, the moisture increases, helping plants cope with excessive heat.
What Are the Benefits of Having a Mini Greenhouse?
Investing in a mini greenhouse is one of the best things you can do for your garden. It’s economical, convenient, and you’ll get the same benefits as a regular-sized greenhouse. If you’re still on the fence, here are some of the reasons why having a greenhouse is a great investment.
Many varieties to choose from
Some people think that greenhouses are made of floor to ceiling glass as big as a house. While there are extravagant greenhouses, most of them come in many shapes and sizes. A good greenhouse doesn’t always have to be large and spacious. Mini greenhouses are great for home gardeners who want to grow plants in their backyard.

Keep your plants safe from harsh weather

For example, some states generally have excellent growing conditions, but it only takes one severe storm to wipe out months of hard work.
Perfect for gardeners with limited space
Mini greenhouses are perfect for gardeners who have limited space. Don’t let these constraints stop you from growing your own fruits and vegetables. You can place your mini greenhouse anywhere – from balconies, patios, decks, and even on tabletops. Even though it’s small, these greenhouses will give you the same benefits as a regular-sized greenhouse.

Once you know your preferences, you’ll be able to decide whether you want to invest in greenhouse gardening.
