All You Need To Know About Greenhouse Temperature Difference

Let’s talk all about greenhouse temperature difference; here is the answer to all your worries, for sure. Temperature differs between the inside and outside of your greenhouse. Many factors affect the temperature difference, such as climate.

Greenhouses lengthen the growing season of plants. It achieves this by mimicking the optimal temperature for plants all year round. Some crops, for example, tomatoes, prefer warmer temperatures. You can control the temperature of your greenhouse to suit this.

We’ll be explaining all about greenhouse temperature difference; how it works.

All About Greenhouse Temperature Difference

The Ideal Temperature

Do you want to know all about greenhouse temperature difference? Well, the general ideal temperature for the inside of your greenhouse is 27 – 29°C, any higher and you’ll be burning your plants. Of course, this still depends on the needs of your plants.

For example, melons prefer warmer temperatures. Meanwhile, radishes prefer cooler temperatures. You know you’ve maintained the right temperature based on your plant’s appearance.

Their growth is affected by temperature. If you see brown and bruised skin, that means you failed. Damaged plants have shorter growing seasons and decreased crop production.

Maintain ideal conditions, and you’ll have healthy plants throughout the year.


How It Works

If you want to understand all about greenhouse temperature difference, you have to know how it works. Greenhouses trap heat and make the temperature inside warmer. Sun exposure, climate, and ventilation directly affect the interior temperature.

Consider temperature difference during night and day time. The sun warms your plants. But, the night is cold with no natural heat source. You can use artificial heat sources to warm your greenhouse.

In that respect, the material of your greenhouse also affects the temperature. Plastic, in comparison to glass or polycarbonate, does not retain as much heat.



During the hot days, you need to regulate the temperature to make it cool. In this case, the inside will be more desirable than the already hot outside. Your plants will not be feeling too good.

What you’ll need are shade, ventilation, and some fans. Monitor the temperature by installing a thermometer.



Ventilation gives better air-flow. It can be a roof or side vents and even your greenhouse door. Ventilating releases the hot air that’s accumulating inside. In turn, it allows fresh air to pass through your plants. Of course, there are also automated vents available.



Fans are also a great companion to help you with this task. Add nets over the door to keep away pest, like your neighbor’s cat, out. Be sure the net can allow pollinators, such as bees and butterflies, to pass through.



Shading is the next defense in your arsenal. When the heat burns too hot, shade your plants. Shade paint is a quick and economical method to weaken the sun’s rays. You can paint more layers as throughout summer, then remove as it gets colder. However, they’re not suited for all greenhouses.



Blinds are a double-edged sword. They can effectively shield your plants, but they can also block the vents. You can find ways to work around it or buy automated internal blinds. Don’t worry; blinds can be removable. You can remove them when the heat passes.



Your secret weapon though in cooling your plants, is damping. Do this by wetting the pathways and staging in your greenhouse. The more water that evaporates, the more moisture in the air there is. Doing this helps stave off the heat.

Damp down your greenhouse often, especially when it’s too hot. But if you can’t, at least once in the morning and evening should do.



In the winter, your main objective is to stay heated. Insulators and snow will be your two happy helpers.

The cold reduces daylight hours. Thus, leaving around 5-6 hours of sunlight. But proper insulation can retain a warmer temperature than outside air.

So long as the temperature is consistently above 0°F, you don’t have to use an artificial room heater.

Ironically, the snow covering your greenhouse can act as an insulator. Much like an igloo, the snow has air pockets that prevent heat loss.


Bubble wrap

Another insulator you can use is bubble wrap. Bubble wrap permits sunlight to pass through while also trapping warm air in its air bubbles. The trapped air disperses at night.


Frost cloth

Frost cloth allows water through while retaining heat. The soil absorbs the heat during the day and releases it at night. Frost cloth prevents the heat from escaping while also protecting the plants from cold.


Ventilation system

Keep humidity levels low at this time. Ventilation and fans will keep the air temperature consistent and prevent unwanted humidity.

It may not seem to make sense, but it does. If you don’t release the hot air occasionally, it will rise, and the cold air will gather below where your plants are. Cooler air carries less moisture, and so lowers the humidity levels.

So adjust your ventilation system to ventilate at least once per day or longer. Doing this gives your plants fresh and warm air. If all else fails, you can use artificial heat sources such as electric room heaters and heat lamps.



The temperature of your greenhouse has many factors affecting it. An example would be climate and sun exposure. But, you have many methods to control it as well.

During summer, shade, damping, and ventilation will save you. While in winter, insulation and ventilation are your happy helpers. The material of your greenhouse also comes into play. It’s all about consistent monitoring of your temperature and hard work.

Hopefully, through this article, you’ve understand all about greenhouse temperature difference.

How to Start an Avocado Farm: 4 Things to Remember

How to Start an Avocado Farm: 4 Things to Remember

Are you interested to learn how to start an avocado farm? Embarking on this journey requires time, effort, and commitment. Plus, you need to consider a number of factors including soil preparation, as well as weather conditions.

You’re probably aware that avocado trees or Persea spp, are originally from Mexico. This explains why one of the famous Mexican cuisines include avocado-based guacamole.

You can choose to grow avocado trees indoors or outdoors. If you plan to grow them in a hobby greenhouse or at home, all you have to do is to sow the seeds in pots. When they’re grown outdoors, avocado trees can grow up to 40 feet. You can al

Moreover, these trees thrive well in regions where the weather is mostly warm and sunny. However, don’t expect them to grow in areas that experience extreme temperatures during the summer and winter.


Avocado: The Superfood

Did you know that the global demand for avocados has been steadily increasing? Aside from the fact that its fruit is known for its full, buttery flavor and rich texture, it’s also packed with loads of essential nutrients that are good for your body.

A single serving of avocado fruit contains vitamin K, vitamin C, folate, potassium, vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin E, manganese, magnesium, iron, copper, zinc, and vitamin A.  It also has protein, fiber, and healthy fats. If you’re on a low-carb plant food diet, you’d want to incorporate avocados into your diet.


What are the Growing Requirements of an Avocado Tree?

Since avocado trees need to be grown in warm semi-humid climates, they only grow in U.S. Department of Agriculture (USDA) plant hardiness zones 8 to 11. However, it’s important to note that while avocado trees may be grown in those zones, they don’t always thrive well in areas that get extremely hot during the summer or frosty, chilly, or snowy in the winter. This implies that the ideal environment for an avocado tree should have moderate temperatures all-year-round.


What are the 3 Primary Groups of Avocado Trees?

If you’re planning to start an avocado farm, you need to know the 3 main groups of avocado trees: Guatemalan, West Indian, and Mexican. Each type has its own ideal growing range.


Guatemalan Avocados

A Guatemalan avocado is known for its hard skin that features plenty of warts.


West Indian Avocados

This type of avocado tends to flourish in warm climates. Unlike the Guatemalan avocado, a West Indian avocado has thin and shiny skin and could weigh up to 5 pounds.


Mexican Avocados

A Mexican avocado thrives well in tropical highland areas. Compared to the other avocado groups, the Mexican avocado is more tolerant of cold weather. In fact, it can manage to survive even when temperatures drop to 26˚F.

Moreover, this type of avocado produces smaller fruit that weighs less than a single pound and its skin has a distinct papery-smoothness to it.


Expert Tips on How to Start an Avocado Farm

Unless you’re willing to take on a long-term project, spend a considerable amount of money on planting, and wait for a period of 3 to 5 years for your first harvest, don’t get into avocado farming. However, if you’re willing to go through the whole nine yards to enjoy top yields for many years, check out this guide:


Tip #1: Plant them in areas where the temperatures are consistently cool

Be sure to plant your avocado trees in cool temperatures that can range between 68˚F to 75˚F on a daily basis to avoid fruit drop. However, when they’re flowering, or when they’re starting to bear fruit, the humidity levels shouldn’t go below 50% at midday.


Tip #2: They don’t like wind

In case you’re not aware, avocado trees have brittle branches that easily snap off. For this reason, it’s best not to plant them in areas that are mostly windy because wind can cause considerable damage to their fruit.


Tip #3: Most of them need proper irrigation

If your avocados are rain-fed, they need to have at least 1,000 mm rainfall spread out throughout each year. Before their flowering season, avocado trees require a drier season that lasts for about 2 months. On a weekly basis, avocado trees need about 25 mm water.

It’s extremely important to test the quality of irrigation water because if its pH and bicarbonates are really high, they trigger a build-up of free lime in the soil. You also need to remember that high levels of sodium and chloride can have a negative impact on your avocado plants.

Since the plant’s roots are shallow, the ideal way to apply water is via a micro-sprinkler or drip. This ensures an even distribution throughout the avocado tree’s root area.

Moreover, proper moisture control needs to be ensured in the root zone because this area tends to easily dry up.


Tip #4: Determine the soil’s suitability and prepare it accordingly

You can’t just plant an avocado seed on soil that hasn’t been prepared accordingly. To prepare the soil for planting, you need to dig soil profile pits throughout your farm. Make sure that the pits are 1.5 m deep.

Only a single put per ha is required. However, you need to dig more pits if the location is non-homogenous or hilly. Check the color of the soil, its texture, structure, patches, sitting water, concretions, hardpans, stones, and gravel.



Grow Your Avocado Trees in a Hobby Greenhouse!

Since avocado trees require specific levels of temperature and humidity, you’ll find it easier to grow them in a hobby greenhouse. The enclosed space allows you to customize the environment to meet the needs of your plants. What’s more, it protects them from strong winds and the constant threat of pests.

Learning how to start an avocado farm outdoors is great, but growing them inside a hobby greenhouse is even better.
