How Hot Can a Greenhouse Get

Highest Temperature

Wondering how hot can a greenhouse get? The sides of a greenhouse can have a maximum temperature of 100 degrees Fahrenheit on a regular sunny day.

During the summer season, the temperature can become super hot, so temperature regulation is critical since some plants can’t live with extreme conditions.

Shade, ventilation, and humidity are the factors that enable you to cool down your greenhouse to have a healthy plant. Always bear in mind that too much heat from the sun may result in killing your plants.


What Is The Ideal Temperature In A Greenhouse?

If you love tomatoes and melons, your greenhouse should be warmer. A suitable greenhouse assists your plants in growing correctly and healthy.

The most appropriate temperature for a greenhouse is 27 degrees Celsius. Maintaining this means a good harvest, more production, and more money.

Humidity and temperature can accumulate faster if you have lots of plants, so applying the needed measures is essential.


Tips For Controlling Temperatures

The ventilation and sunlight are the factors that affect the temperature in a greenhouse. Unlocking the doors and windows at the roof may contribute to the cooling down. 

For others who have an extra budget, they usually invest in air conditioning to make sure the temperature is tolerable.

You can install roof vents, side vents, and a door to let air pass, making the area less hot. Having a thermometer can also help you to know the current state of temperature. On sunny days, always bear in mind to open any possible way of letting the air enter.

Plants depend on light to grow. Shading your greenhouse can be a useful idea to be used as a weapon for lowering heat. You can use shading paints to have a faster and budget-friendly way of filtering the sun’s strength.

Blinds can also help. There are two types of blinds, external and internal. The most useful is external because it helps filter sunlight before it passes in the glass, making the heat stay inside. It is also removable and can be removed during colder days.

If you’re looking for a cheaper solution, mesh and nets can become an alternative to the blinds but ensure that it is clipped together.

Another way is to damp the greenhouse during extreme weather. The humidity increases inside and helps the plants to withstand the heat. With this, you can also avoid pests that commonly thrive in dry conditions. You can often do this but make sure you don’t overwater.


Tools That You Can Use In Lowering Heat

If you’re having a hard time controlling the temperature, keep in mind that you can always use some tools. A thermometer is a must-have inside the greenhouse. With just one glance, you will be able to keep informed about the minimum and maximum temperatures for the past 24 hours.

An automatic vent opener can also do the work for you. It helps by responding to the appropriate actions. Its piston is a nonelectric response to the high temperature by expanding and pushing the vent open.

Installing a fan is a great choice. When the temperature is bad, and the air is not moving, different illnesses can be spread throughout the greenhouse. Having this item makes a reasonable disease control and also lowers the temperature a little bit.

A shade cloth which is masks the greenhouse will block the heat from further entering. When you buy, this has different densities. Choosing a large type of density makes the fabric darker, which means a cooler temperature.



A common knowledge that a greenhouse maintains an ideal condition for your plants to live even with having different seasons.

So how hot can a greenhouse get? The greenhouse can get hot during summer days, having a maximum temperature of 100 degrees Fahrenheit; thus, it is crucial to have temperature control.

The optimum temperature for a greenhouse is 27 degrees Celsius. Under this condition, you can have healthy plants. If you are having a hard time controlling temperatures, you can always use tools to help lower the heat.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
