Greenhouse Plants List: Everything You Need To Know!

Do you want to know some greenhouse plants list? The list of plants to grow in summer in the greenhouse is vast, so year-round productivity is achievable.

You can grow various plants such as peppers, herbs, squash, eggplants, green onions, okras, melons, beans, greens, and tomatoes. The summer season doesn’t have to be a problem for farmers because the greenhouse makes it possible to grow these various crops.

Can You Use A Greenhouse In The Summer?

You don’t need to halt the productivity in your greenhouse when summer starts. Actually, a lot of crops would thrive well in the heat. However, make sure that you still check the greenhouse conditions as very high temperatures can affect the plants’ health. 

Here’s the greenhouse plants list:



Crops like tomatoes originate in warm places, making them suitable to grow in the greenhouse in summer. They came from South A

America, where the temperatures get high. Therefore, they’ll still grow healthily inside the greenhouse during warm summers. 



Pepper varieties such as hot peppers and bell peppers also originate in warm regions. In fact, hot pepper seeds even prefer a warm temperature to germinate. What’s great about peppers is that depending on how hot it is in your greenhouse, you can harvest them fresh or dried. 



Most greens that you use in a salad grow well in the greenhouse in summer. They include heat-tolerant varieties of lettuce, romaine, cabbage, watercress, and asparagus. They can grow quickly as long as you give them good hydration by targeting their roots with water. 



A lot of herbs ranging from dill, parsley, chives, thyme, oregano, marjoram, sage, rosemary, and basil, thrive in a greenhouse during summer. However, do note that herbs like thyme and oregano do not need as much water as plants like basil. Nevertheless, the heat in the greenhouse can help you preserve the cuttings of these herbs.



Varieties of beans like yard-long beans and green beans grow well in the heat. They make great crops for the greenhouse in the summer because of their productivity. If you want to achieve a good harvest every summer, beans are an excellent choice. 


Squash and zucchinis

The warm condition in the greenhouse during summer is great for squash and zucchini. Varieties like the Trombetta will go well with the other summer crops in the greenhouse. 



Some varieties of eggplants came from Southeast Asia. These long and narrow eggplants flourish well in the summer. Just make sure to harvest them immediately once you notice that the fruits’ skins are getting dull. 



Okras came from Africa, which makes them a good candidate to plant in the greenhouse during summer. Depending on the variety, you can even harvest the pods frequently. 


Green onions

With proper care, green onions will grow well in the greenhouse in summer. Just make sure the seedlings are spaced well in loosened soil with fertilizer. 



Melon varieties like watermelon, honeydew, and cantaloupe are productive fruits to grow in the greenhouse during summer. However, you still need to check if the inside’s condition provides proper ventilation so that they don’t overheat. 


Can You Use A Greenhouse In The Summer?

The beauty of greenhouse farming is that you can still use it in the summer. Compared to field growing, you always have some control over the conditions inside the greenhouse. You just have to know how do you keep a greenhouse cool in the summer and what crops will thrive well in this condition. 

Using a greenhouse in the summer means making sure that the conditions inside will still be habitable for the summer crops you’ve chosen. This can mean checking the ventilation and humidity, adding shade, and examining for pests.  


How Do You Keep A Greenhouse Cool In The Summer?

Crops such as tomatoes, peppers, greens, herbs, beans, squash and zucchinis, eggplants, okras, green onions, and melons grow well in the greenhouse during summer. However, you still need to keep the greenhouse cool by using shade cloth, proper ventilation, cooling system, and thermostat. You must always maintain the proper temperature inside the greenhouse during the summer.  


Shade cloth

The easiest way to cool your greenhouse in the summer is by using shade cloth. This will help lessen the intensity of the light that penetrates the greenhouse. In turn, you can prevent overheating of plants from getting very intense direct sunlight. 

Sunlight is essential for photosynthesis, so you should understand that you’re not aiming for total darkness in the greenhouse. You can regulate the light intensity by putting the cover during the hottest hours, and then remove it once it’s not as intense. 


Proper ventilation

The ventilation in the greenhouse plays a significant role in keeping it cool in the summer. You can do this by using natural or mechanical ventilation systems. Proper ventilation will make sure you can let cool air inside and then take the hot air outside from the greenhouse. 

Natural or manual ventilation is through the use of air vents, mesh cloth or screen. Or, if you want, you can also use mechanical ventilation systems that will automatically work the vents and exhaust fans for you. Both natural and mechanical ventilation systems will ensure that you can manage the summer temperature in your greenhouse. 


Cooling system

In some areas, you will need to install a cooling system in terms of fans and evaporative cooling systems to regulate your greenhouse temperature. Your location may have a more intense heat during the summer compared to other regions, so you need to reinforce a cooling system in the greenhouse. 



To keep the greenhouse cool in the summer, you can also place a thermostat in your greenhouse. What this does is that it will help you monitor the conditions inside your greenhouse. This way, you will know if you need to make adjustments and reinforcements in the greenhouse. 


How Can I Cool My Greenhouse Without Electricity?

You may think about how it wouldn’t be cost-effective to rely on electricity for cooling the greenhouse every summer. How can I cool my greenhouse without electricity? Shading, manual ventilation, and misting are effective ways to cool the greenhouse every summer without electricity. 



By having the proper amount of shade, you can control the greenhouse temperature and ensure the growth of quality crops.  You can do this by adding a shade cloth or shade paint, and both of which do not require electricity to work.

Plants require light for photosynthesis, so you must know when should you add shade and how much is needed by your plants. The climate in your region is also a significant factor to know how much light your crops will get every summer.


Shade cloth

The concept of shading with shade cloth is as straightforward as using a big curtain that you can open or close in the greenhouse. You can either have it inside or outside, depending on your climate. For example, having the shade cloth outside every summer will reduce the intense heat more efficiently. 


Shade paint

Shade paint is a paint that is capable of blocking solar radiation from penetrating the greenhouse. You will use it outside the greenhouse, and it’ll need reapplication every year. However, because it’s painted, you can’t really adjust the amount of sunlight you’re blocking. 


Manual ventilation

The effect of ventilation on the airflow is the reason why it plays a role in cooling the greenhouse. However, you have the option to have a manual ventilation system if you don’t want to use electricity. With a manual ventilation system, you’ll be the one who’s in charge of opening and closing the vents. 

It’s a straightforward concept because you’re opening them when it’s hot, and then closing them when it gets cooler. Therefore, you want to open the vents after sunrise and then close them at nighttime. For maximum efficiency, remember to have both the sidewall vent area and ridge vent area at 15 to 20% of the floor area. 



Just like us humans, you can cool your greenhouse by damping it down. You’ll only need to spray down on the hard surfaces every time the temperature gets very hot. This results in a moist and humid environment that will be helpful for the plants to survive the heat of the summer. 

There is no exact number that you must abide by regarding how often or how much you need to mist your greenhouse. However, it’s good that you do it simultaneously when you’re opening and closing the vents. 


What Is Too Hot For A Greenhouse?

It’s too hot for the greenhouse if it reaches a temperature above 40°C. This temperature will be too critical for photosynthesis, and the damage will already be irreversible at this point. Getting at this temperature and above it will be detrimental to your plants, so it’s important to cool the greenhouse, especially in the summer. 


Do Greenhouses Need To Be Heated?

Greenhouses need to be heated if it is winter or if you live in a region with a cold climate. Just like with very high temperatures, very low temperatures can cause damages to your crops. You can identify the appropriate heating system for your greenhouse by calculating its heating requirements


How Do You Keep A Small Greenhouse Warm?

With a small greenhouse, you have the option of relying on insulation, solar energy, and an electric heater to keep it warm. Choosing a heating system depends on which matches your ideal needs and requirements. Consider how much you’re willing to invest in the costs, and which system will be convenient for you in the long run. 


Insulating your greenhouse is a simple yet effective way to keep it warm when needed. In particular, a well-insulated greenhouse will not have any problems even though it might get very cold at night. You can check for air leaks and use bubble wrap or plastic sheets to your greenhouse walls to keep them insulated. 

Solar energy

You can keep a small greenhouse warm by designing it in such a way that it will get hit by solar energy directly. Position your greenhouse so that its north wall is opposing the south border of your home. Then, add a water-filled barrel inside the greenhouse, which will serve as a target for the sun’s electromagnetic radiation. 

Electric heater

The beauty with a small greenhouse is that even though you use an electric heater, it wouldn’t be too expensive. It’s small enough that using the heater for a few hours will already be effective in keeping the temperature warm. Use an electric heater with a timer for a more convenient way of heating your small greenhouse. 

Electric heaters with a built-in thermostat will even make the job easier. After all, it will only turn on when the temperature gets too cold. This lessens costs and adds to the convenience, especially when you’re away. 


What Can I Grow In A Heated Greenhouse?

The crops you can grow in a heated greenhouse are similar to those you can grow in summer. These plants include vegetables that thrive in heat, such as tomatoes and pepper varieties like bell peppers and jalapeno. You can also grow beans, squash, okras, and cucumbers in the heated greenhouse. 


Bottom Line

The list of plants to grow in summer in the greenhouse is composed of tomatoes, peppers, greens, herbs, beans, squash and zucchinis, eggplants, okras, green onions, and melons. These crops have varieties that can tolerate the heat, so you can still grow them in your greenhouse year-round.  However, it’s crucial to maintain the conditions inside the greenhouse to keep the plants healthy. 

So how do you keep a greenhouse cool in the summer? You can cool the greenhouse in the summer using shade cloth, proper ventilation, cooling system, or with a thermostat. Adding these reinforcements will help you minimize the heat during the summertime. 

Overall, always check the temperature in the greenhouse during the year when it gets extreme. You don’t want the greenhouse to reach 40°C because it damages the plants’ capacity to perform photosynthesis. On the other hand, you also have to heat the greenhouse during winter to keep the area habitable for your crops. 

Hopefully, you’ve learned from this greenhouse plants list!

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.
