All About Greenhouse Temperature Difference

With the greenhouse temperature difference, you can have your microclimate regardless of the weather outside. There’s so much more to greenhouses than extending the growing season and protecting plants from the elements. It’s the perfect space to grow out-of-season plants all year round – even in the coldest months of the year!

All About Greenhouse Temperature Difference

Do You Need to Heat a Greenhouse?

It depends on where you’re located. Plants mainly need four things to survive: water, sunlight, air, and nutrients. They undergo chemical reactions (respiration and photosynthesis) to grow healthy. To do that, your plants need energy in the form of heat/sunlight. If the temperature is too low, the growth of your plants slows down.

Gardeners in warmer climates with moderate temperature drops during winter can use an unheated greenhouse. Sunlight would be enough to raise the temperature, but make sure it doesn’t overheat on days with high humidity.

On the other hand, if the weather is below freezing, the thin layer of plastic or glass won’t be enough to keep your plants protected. You may need to insulate it to keep your plants happy. While some areas still get a lot of sun during winter days, an uninsulated greenhouse will cool off during the night. If this is the case, you may need to install a heating system.


How Cold Is Too Cold for a Greenhouse?

Since you can use a greenhouse to create your microclimate, you can use one as a hothouse or cold house. You can even have two climates in one greenhouse!

If you live in colder regions, like Montana, North Dakota, and Maine, you may prefer to keep your greenhouse warm and heated. The minimum nighttime temperature should be at least 55 degrees F.

For those living in warmer regions and prefer a cooler greenhouse, you can set the temperature to 45 degrees F. The maximum temperature for your greenhouse should be 90 degrees F during the daytime, all year round.

To maintain this temperature, regardless of the outside weather, there are ways to keep your greenhouse warm during winter. On the other hand, too much heat can damage your plants as well. If the sun is blazing, you can draw a shade at the top to block the heat.


What Are Cost-Effective Ways to Heat a Greenhouse?

There are different cost-effective ways to keep your greenhouse warm. Since greenhouses don’t stay warm in the winter, notably a full glass greenhouse, you want to protect your plants from harsh winter weather.

Here are some of the most cost-effective ways to do so:



Insulating your greenhouse is vital in keeping your plants alive during winter. You can cover the windows and doors with bubble wrap to retain the heat. The bigger the bubbles, the more effective it is for insulation.


Install a cost-efficient heater

You don’t have to shell out thousands to install a heating system in your greenhouse. A heater running throughout winter will keep your plants warm throughout the season. You can use a digital thermometer to monitor and determine the greenhouse temperature difference.



To prevent your greenhouse from overheating, make sure that there’s enough ventilation throughout the area.



If the sun directly hits your greenhouse or if you live in an area with humid summers, shading your plants from the sun prevents them from getting burned. You can use roll-up screens made of aluminum or wood, paint-on materials, polypropylene shade cloth, and vinyl plastic shading.


Raise your plants off the ground

Most plants cannot survive in low soil temperatures. Raising them off the ground is the best solution to keep the coldness of the soil from transferring to your plants. You can recycle old pots or any other container.


Why Are Greenhouses Worth the Investment?

Greenhouses are one of the best investments every gardener should consider. Here are some of the many reasons why greenhouses are an excellent investment:


Ideal Growing Environment

Whether you want to grow fruits, vegetables, or ornamental plants, growing them in a greenhouse keeps them warm and humid all year long.

You can customize your greenhouse to ensure that your plants are in their ideal growing environment. With a greenhouse, you’ll have enough heat and water vapor to maintain a warm climate even if it’s snowing outside.


Protect your plants

Keeping them in a greenhouse protects your plants from harsh weather, an infestation of seasonal pests like spider mites, locust swarms, and more. Keep your plants safe and healthy throughout the year.


Grow plants all-season

Want to grow an exotic plant? Or perhaps you want to plant tropical fruits in your area? Many gardeners know that some plants thrive best in certain seasons. If you invest in a greenhouse, you don’t have to wait for months before you can plant tomatoes, strawberries, or exotic plants.

With a greenhouse, you can control the climate and the temperature. This means you can start planting seasonal plants anytime you want.


Maintaining a Greenhouse Temperature Difference Won’t Burn a Hole in Your Pocket

You don’t have to spend a fortune to maintain a greenhouse temperature difference. Whether you’re preparing your greenhouse for spring or winter gardening, be sure to keep these tips in mind.

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.
