Greenhouse Temperature Difference: 12 Tips On Choosing The Best Greenhouse Site

To all your concerns, this is the solution: the greenhouse temperature differential. Your greenhouse has different temperatures inside and outside. Climate, for example, has a significant impact on temperature differences.

Plants’ growing season is extended thanks to greenhouses. All year round, it mimics the ideal temperature for plants. Tomatoes, for example, thrive in a more hospitable climate. This can be accommodated by adjusting the greenhouse’s temperature.

We’ll go through how greenhouse temperature differential works and why it’s important.

The Ideal Temperature

Do you want to know everything there is to know about greenhouse temperatures? Generally speaking, the ideal temperature for your greenhouse is between 27 and 29 degrees Fahrenheit; much higher and your plants will be burned. Of course, the demands of your plants must still be taken into consideration.

Melon, for example, does better in warmer climates. Radishes, on the other hand, prefer it cooler. Your plant’s appearance will tell you if you’ve kept it at the appropriate temperature.

Temperature has an effect on their development. Seeing discolored and bruised skin is a sign that you didn’t do a good job. Plants that have been damaged have shorter growing seasons and lower yields.

Your plants will thrive all year long if you keep them in the best possible conditions.

How It Works

Understanding how greenhouse temperature difference works is essential to fully comprehending it. Heat is trapped inside greenhouses, which raises the temperature. Temperature is directly influenced by the amount of sunlight, the weather, and the amount of ventilation.

Consider the difference between the temperature at night and during the daytime. Your plants benefit from the warmth of the sun. With no natural source of heat, the night is frigid. To warm your greenhouse, you might make use of electric or gas heaters.

Your greenhouse’s material has an impact on the temperature in this way as well, of course. Plastic, unlike glass or polycarbonate, does not retain heat as well.

Summer

In order to keep cool on hot days, you’ll want to adjust the thermostat. Inside will be more appealing than the already sweltering outside in this instance. Your plants aren’t going to be in the best of spirits.

Shade, ventilation, and a few fans are all you’ll need. Install a thermometer to keep tabs on the ambient temperature.

Ventilation

Ventilation improves the quality of the air. There are a variety of possibilities here, including your greenhouse’s roof, side vents, or even the door. The heated air that has built up inside can be disbursed by opening the windows. As a result, your plants get more air to grow in. However, there are also automated vents to choose from.

Fans

Fans can also be a wonderful helper in this endeavor. Protect your home from vermin, such as the neighborhood cat, by installing nets over the entryway. Keep pollinators like bees and butterflies in mind when making your net.

Shading

Your next line of defense should be shading. Protect your plants from overheating by placing awnings over them. To reduce the intensity of the sun’s rays, shade paint is an effective and quick solution. It’s possible to paint more layers during the summer, then remove them when the weather gets cooler. However, not all greenhouses can use them.

Blinds

The use of blinds can be both beneficial and detrimental. They can protect your plants well, but they can also obstruct ventilation. To get around this, you can install automated inside blinds or discover a workaround. Fortunately, blinds are easily removed. Once the heat has dissipated, you can remove them.

Damping

However, damping is the key to keeping your plants cool. Wet the paths and staging in your greenhouse to accomplish this. Moisture in the air increases as more water evaporates. This helps keep the heat at bay.

When it’s hot outside, make sure to often mist your greenhouse to keep it from drying out. Once in the morning and once in the evening will enough if you can’t.

Winter

When it’s cold outside, the most important thing to do is to keep warm. With the help of insulators and snow, you’ll be all set.

The onset of winter limits the amount of time the sun is visible. That leaves about five to six hours of sunlight for the day. Insulation, on the other hand, can keep a room warmer than the air outside.

You don’t need an electric space heater as long as the temperature remains continuously above 0°F.

The snow that covers your greenhouse can, in a strange twist of fate, act as an insulator. The snow, like an igloo, is filled with air pockets that help keep the temperature inside stable.

Bubble wrap

Bubble wrap also works as an insulator. With its air bubbles, bubble wrap allows light to travel through, while simultaneously trapping warm air. During the night, the trapped air is released.

Frost cloth

Allows water through while keeping heat During the day, the soil absorbs heat, and at night, it releases it. Frost fabric acts as a barrier to keep heat in and cold out, while also protecting plants.

Ventilation system

At this time, you want to keep the humidity at a minimum. It’s important to keep the air moving to keep the temperature stable and prevent the buildup of moisture.

Even if it doesn’t make sense at first, bear with me. Hot air rises and cold air gathers around your plants when you don’t release it from time to time. The lower the temperature, the lower the humidity.

In other words, make sure you’re ventilating at least once a day, if not more. Fresh and warm air is brought into your plants by doing this. As a last resort, you might turn to electric heaters and heat lamps for extra warmth.

5 Steps to Grow Through The Cold In A Winter Greenhouse

1. Winterize… The Right Way

Greenhouse growers have a different reason to clean up in the early winter than those who associate spring with “spring cleaning,” and that is because the changing weather calls for it.

The “winterizing” procedure is a common occurrence for greenhouse owners, regardless of whether or not they intend to grow during the winter months. As a general rule, this is the time of year when you can finally get your greenhouse in top operating order before the first snow of the season hits. This entails removing all organic matter from the greenhouse and carefully cleaning and sanitizing the walls and equipment.

A good time to inspect your greenhouse’s moving parts for any repairs or replacements that may be needed before the snow begins to fall, which will assist ensure a healthy and happy greenhouse even when the temperature dips below zero degrees.

2. Pick The Right Crops

Have you ever tried to cultivate a mango in the arctic? In order for the plant to thrive, it needs more light and heat than can be provided by the frigid environment. Even if you’re able to grow all year round, you may run into the same issues while trying to do so in the winter.

That’s why it’s so important to choose crops that can tolerate the extremes of winter weather when planning your winter garden. Despite the fact that a greenhouse can help protect your plants from the worst of winter’s elements, producers in colder regions should still go for hardy root crops and leafy greens like spinach and collards.

3. Light Well

It’s impossible to grow anything edible in the dark. That’s why so many crops begin to falter as the days become shorter and the nights get longer as the sun begins to set earlier and earlier. Cold-tolerant crops can be grown in the dark period of the growing season.

4. Control Heat & Humidity

The colder the weather outside your greenhouse, the more heat you’ll need to keep your greenhouse comfortable. You may not be able to keep your crops growing till spring even if the weather is warm in the south or harsh in the north. That’s why, if your crops demand it, a properly designed and effective supplemental heating system for your winter greenhouse may be necessary.

But plants aren’t the only ones who benefit from warmth in the winter months. You may want to keep an eye out for diseases that thrive in warm and humid conditions, such as those that thrive in a greenhouse. In order to avoid illnesses from affecting your crops, you must ensure that your humidity and heat levels are in balance, either by correct ventilation or effective dehumidifying devices.

5. Harvest Efficiently

First-time winter producers sometimes make the blunder of treating the winter harvest as if it were spring or summer. In contrast to other times of year, winter harvests should be spaced out over the full year. This includes arranging your harvests wisely, letting plants that can recover to do so, and harvesting only when necessary.

Row-by-row harvesting is popular among winter growers, who design their beds such that they may be harvested one at a time, giving the first harvested rows time to regrow and replenish their populations while the remaining rows are being picked. So, even if the number of fresh vegetables gathered is reduced, the cycle will continue until spring arrives. A winter farmer’s market would not be complete without a steady supply of fresh produce from local growers.

12 Tips On Choosing The Best Greenhouse Site

Solar radiation:

It’s important to know how the sunlight will reach the plants because they need it for photosynthesis. Low light inhibits photosynthesis, resulting in stunted development and the premature ripening of fruits and flowers. In the end, the yields are modest and the financial returns are small. If your greenhouse is located in a place that doesn’t get enough sunlight in the winter, you’ll need to supplement it with artificial lighting.

Water:

In addition to the 10,000 to 15,000 gallons of water per day required for evaporative cooling, each plant requires roughly 1 gallon of nutrient-mixed water each day. Be aware of salt build-up when recycling nutrient water to improve water use efficiency. To determine the salt and pH levels in the water, a preliminary water analysis is recommended. Adding acids like sulfuric, phosphoric, and nitric to water with more than 7 parts per million of basicity is recommended for tomatoes. Add a base to the water if it is acidic (pH less than 7).

Elevation:

Your cooling and heating bills will rise and fall depending on the elevation of your home. Tomatoes, for example, perform best when kept between 59°F and 86°F. In the event that you find yourself at a higher elevation than usual, the following suggestions can help you keep cool:

Take care of your plants by placing plastic bottles of water around them in the winter. During the day, the water absorbs heat and stores it for use at night.

The colder months are the perfect time to set up a temperature alarm in your greenhouse. Ceramic heaters can be used to raise the temperature of a home if necessary.

In a hard structure greenhouse, use an automatic vent opener to adjust the heat, whereas in a soft structure greenhouse, you can open a flap to regulate the temperature.

Make sure you have an automatic watering system in place throughout the hottest months of the year. In the winter, detach all hoses and use water by hand to avoid pipes from freezing.

Microclimate:

It is possible for a wide range of variables, such as latitude, to influence your immediate surroundings. Polar sea levels will always be colder than equatorial sea levels, and huge amounts of water warm and cool more slowly than land masses. For example, the temperature swings in San Diego, which is right next to the Pacific Ocean, are much smaller than those in the Sonoran desert, which is far from the ocean and hence subject to enormous swings in temperature.

Even in the early morning hours, trees, mountains, and other barriers may produce shadows on the greenhouse. Wind and storm patterns can also be affected by mountains. Snow, grit, and sand all have the potential to melt greenhouse glass, which should be taken into account when planning a greenhouse project. Also keep in mind that fog and clouds might gather at specific times during the day and restrict sunlight, which is bad for photosynthesis.

Pest pressure:

Prevent pest infestation by either locating your operation far from other agricultural production regions or establishing a buffer zone between it and those areas.

Level and stable ground:

Consider the stability of the ground on which you build your greenhouse; it should not change. Additionally, the ground must be graded to allow water to flow away from the building (a 6 inch drop in 100 feet). Ground must also be compacted before the greenhouse is built so that it doesn’t begin to settle afterward.

Utilities:

The following tools should be at your disposal:

The use of a telephone

Three-phase electrical power.

Natural gas, propane, fuel oil, and electricity are all options for generating heat and CO2. Solar, compost, woodchips, and nut hulls are a few of the alternatives.

Roads:

There must be easy access to a network of well-maintained roadways. For example, if you’re transporting your harvest across gravel roads, the fruit will be vulnerable to the rocky movement of the truck, which could lead to bruising, crushing, and other serious damage.

North-South orientation:

The greenhouse and the plants inside the greenhouse should be orientated north-south, especially in southern latitudes, in order to maximize light and ventilation.

Capability of expansion:

If you plan on expanding your business in the future, it’s best to buy more land than you need now.

Availability of labor:

In order to run the business successfully, the owner or manager will require two distinct categories of employees:

Retainable workforce of trained laborers. Plant and fruit picking and packing will be handled by these workers.

specialized workers Growers, plant production managers, plant nutritionists, plant protection specialists, office/computer professionals, labor/management specialists, and marketing specialists are all included in this category.

Management Residence:

In the event of an emergency, the greenhouse’s growers and managers should all be within driving distance.

Conclusion

There are a slew of variables at play when it comes to the temperature in your greenhouse. Climate and solar exposure are two such examples. However, there are numerous ways to keep it under control.

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 all comes down to regular temperature checks and hard labor.

In the heat of the summer, you’ll be glad you have shade, dampening, and ventilation. To keep you warm in the colder months, insulation and ventilation are there to aid you. This includes the type of greenhouse you have and the material it is made of. It’s all about keeping an eye on your temperature and putting in the effort.
