How Warm Does a Greenhouse Get During Winter

Perhaps you’ve wondered, “How warm does a greenhouse get during winter?” It’s no secret that freezing temperatures are not suitable for the plants, whether they’re in a greenhouse or not. To keep them healthy, you need to make sure it doesn’t get too warm or too cold in your greenhouse.

The temperature of your greenhouse varies depending on several factors like climate, greenhouse glazing, outdoor temperature, and more. Generally, the temperature in a greenhouse is 30 degrees F higher than the outside temperature. However, weather, greenhouse glazing, the outside temperature can influence

How Warm Does a Greenhouse Get During Winter

Does a Greenhouse Work in the Winter?

In a word, yes. However, you need to prepare for winter season planting. Some of the factors you need to consider include insulation, pest infestation, and the types of plants you want to grow.



Plants need energy (heat) to grow, so you need to consider your heat source during winter. Hold on to the energy/heat you’re getting by insulating your greenhouse.


Pest infestation

Aside from your plants, pests are also attracted to warmer climates during winter. To prevent pests from doing severe damage, get rid of dead leaves, plants, stone, empty pots, and other materials that can house pests.


Types of plants

Be practical about the type of plants you want to grow in your greenhouse. For instance, if the temperature doesn’t exceed 20 degrees F, it’s best to plant cold-season vegetables and herbs, such as garlic, onion, beans, spinach, shallots, etc.


How Do You Keep Your Greenhouse Warm During Winter?

As mentioned, plants need heat to survive and produce a flavorful harvest. Here are some of the ways you can keep your greenhouse warm during winter:


Add insulation

One of the cheapest ways to add insulation is to use bubble wrap. Aside from protecting fragile packages, a layer of bubble wraps on the wall can retain heat and block the cold. The larger the bubbles, the better the insulation.


Cover your plants

To provide additional warmth, it helps to cover your plants on colder nights. You can use row covers, tarps, and horticultural fleece to hold moisture. If it isn’t winter season, make sure to remove the cover during the day, especially if it’s too humid.

In areas with harsh winter like Montana and North Dakota, you can use frost fabric for added insulation. Frost fabric allows rain and irrigation to flow freely into your greenhouse while retaining heat. If you have plants that thrive best in humid environments, consider putting frost fabric.


Install a heating system

One of the sure-fire ways to keep your greenhouse warm during winter is to install a heating system. However, heaters can be expensive, and the heat will dissipate if you turn the heater off. You can use space heaters specifically made for greenhouses. If you’re not comfortable having extension cords in your greenhouse, opt for propane heaters. Keep in mind that you need to distribute the heated air throughout your greenhouse.


Why Are Greenhouses Worth the Investment?

Home gardeners can benefit from having a greenhouse during winter. If you’re still on the fence, here are some of the reasons why a greenhouse is worth the splurge:


Extend growing season

Greenhouses can extend the growing season of your plants. If you live in Idaho, Oregon, or anywhere in the Pacific Northwest area, summers are cool and short, making it challenging to grow individual plants. Greenhouses allow you to start planting even if there’s still frost outside.

It will also protect your plants from rain, preventing them from becoming mildewy. You can continue harvesting your crop even when the outdoor temperature is colder than usual.


Grow different types of plants

You don’t have to rely on seasons to grow certain plants. If you live in the northern part of the country, then you know how challenging it is to grow warm-season crops. Citrus trees, eggplants, and melons cannot thrive in regions with cold winters – unless you put them in a greenhouse.

By installing a greenhouse with a heating system and grow lights, you can plant and harvest different types of fruits and vegetables. You don’t have to wait for another growing season to start planting. Whether you’re a novice or a seasoned gardener, you can definitely benefit from having a greenhouse.


Protect plants from wind and precipitation

Extreme precipitation can harm your plants, especially the tender ones. After heavy rain, you may notice that some of your plants are bent to the ground. A light layer of snow can destroy an entire garden of fragile plants.

If you often experience frost and heavy rains, growing your plants in a greenhouse is a better idea. You can control the environment by adding insulation, cover, electric heaters, solar heating, and other natural heat sources. This allows you to create a microclimate inside your greenhouse despite outside temperatures.


The Answer to “How Warm Does A Greenhouse Get During Winter?”

There are several options when it comes to warming your greenhouse during winter. You don’t have to spend a fortune to create the perfect climate in your greenhouse. To sum up, the answer to the question, “How warm does a greenhouse get during winter?” depends on the outside temperature and the heating techniques you’re implementing.

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.
