Why Do Plants Grow Better In Greenhouses? 4 Good Reasons!

Why do plants grow better in greenhouses? If you have been pondering upon this question, do not worry because we have an answer to that. The most obvious reason is that the humidity and warmth inside the greenhouse stimulate plant growth.

As we all know, three things are needed for a plant to grow. This includes light, warmth, and moisture.

A greenhouse can stabilize the plant’s growing environment as it maintains the right temperature and protects them from extreme coldness at the same time.

Even though cultivating plants in an outdoor garden lets you soak in the sun, many gardeners still prefer growing inside the controlled environment of a greenhouse. That is because even if there is an unexpected rainy day, you can continue to be productive.

Whether you desire to shift into growing indoors or merely interested in extending the growing season all year round, a greenhouse can be the best thing that can help you with it. Knowing and learning the secrets of the greenhouse will surely change your gardening habit.


The Benefits of a Greenhouse

Advantages Of A Greenhouse

So, why do plants grow better in greenhouses?

In this section, you will know the advantages of growing your plants in a greenhouse.

This will answer the question of why do plants grow better in a greenhouse. It is mainly due to four reasons which we will have to talk about later in this post.


#1. Reduced exposure to disease and pest

The plants inside a greenhouse are grown in containers with soil that are specially chosen for the particular plant. Suppose you compare it with the soil in your outdoor garden.

In that case, it does have the possibility of harboring pests and diseases that can potentially harm the plants.

With that being said, the greenhouse is sterile against bacteria, fungi, as well as pests like borers.

In the absence of those pests and pathogens, your plants can concentrate on growing healthy instead of defending and repairing themselves against those organisms.


#2. Humidity

The transpiration of the plant foliage depends on the consistent supply of moisture from roots. It also relies on its surrounding atmosphere for maximum growth.

The outdoor condition is dry; that is why plants are forced to rely merely on the moisture that the soil can give. This results in water stress, particularly when the roots are exposed in a drought condition.

When the dry condition becomes constant to an outdoor plant, the growth will be affected. Furthermore, their resistance to diseases and pests will reduce significantly.

Gratefully, greenhouses have humidity controls, thereby keeping the air moist indoor for optimal growth of the plants.

Also, if you reduce the water stress of the plants, they can concentrate their energy on flowering and bearing fruits. This will be done by watering the roots.

You might as well provide them with a humid environment just like what a greenhouse does.


#3. Temperature control

The temperature outdoor significantly swing through day and night. Plants that are exposed to extreme heat and cold for 24 hours will not grow well as compared to plants cultivated inside a greenhouse. Much more, exposure to varying temperature can cause stress to the plants. As a result, their growth will be affected.

But since the greenhouse provides you with an indoor space that is enclosed allows you to control the temperature that your plants will have to be exposed to.

In general, greenhouses are integrated with an air ventilation system as well as heaters. In other words, you can control the temperature depending on the particular plant species that you are growing.

More so, the heaters are generally connected to a timer that will allow you to change the temperature settings depending on the time of the day. If only you follow the temperature preferences of the particular plant you are growing fruits, flowers, and foliage will undoubtedly flourish in the controlled space.


#4. Carbon dioxide factor    

If you can control the air indoors, a constant supply of carbon dioxide will be provided to the greenhouse plant. CO2 is vital for the plants in producing their food which is glucose.

Even though outdoor plants have enough supply of carbon dioxide, placing horizontal fans strategically on the entire greenhouse will allow the air to push closer to the plant foliage for optimal photosynthesis activity.

Suppose the carbon dioxide is concentrated towards the plants. In that case, it often results in stronger stems, larger leaves of the plant, as well as early fruiting and flowering. But make sure that the air movement is combined with proper ventilation.

Closing off the greenhouse from the air circulation outdoors will lower the carbon dioxide levels indoors. This is because the plants can quickly use up the gas while it transfers oxygen in exchange.


It’s A Wrap!

Why do plants grow better in greenhouses? For sure, by now, you already know the answer to that question. Plants grow better in greenhouses because it can regulate the temperature and humidity that is needed by the plants to grow at its peak.

Other than that, the benefits of the greenhouse are greater than the sum of their components. Aside from enhancing the potential growth of the plants, it can also improve your gardening hobby in so many ways.

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.
