Greenhouse Temperature Considerations April 19, 2019 – Posted in: Blog

We love to be able to grow our favorite plants all year round but since each plant has temperature requirements it isn’t possible to grow them outside it is possible however to grow them in a greenhouse. Optimal greenhouse temperature is 27°C b because anything above it can damage plants already. The temperature in greenhouse is dependent on the kind of plants you are growing.

If you are growing sun-loving crops such as tomatoes and melons temperature of greenhouse can be warmer. The best greenhouse temperature is the one that best supports your plant’s full growth.  You can know that you have the optimal greenhouse temperature by observing the appearance of your plants.

If you have crops such as tomatoes, they can show unhealthy signs by having bruised skin and brown leaves. In such cases, you may have to discard them since they are not fit to be sold on the market anymore. Maintain your greenhouse in optimal conditions and you can benefit from having healthy plants whatever the season.

What is the perfect temperature for greenhouse?

The perfect temperature for a greenhouse is 27°C. Most plants and vegetables will grow healthy under this temperature. Greenhouse temperature control is important to keep plants growing even during the offseason.

The greenhouse ideal temperature must be maintained because you are growing the plants in artificial conditions and if you don’t manage the greenhouse correctly your plans will die off. Greenhouse temperature and humidity can build up fast if you have a lot of plants in the greenhouse so it is important to apply some measures at controlling it. Equipping your greenhouse with temperature control is a good step.

To maintain ideal greenhouse temperature and humidity on greenhouse temperature winter you can draw in a small amount of the cold outside air while releasing a small amount of the warm and moist interior air. Cooler air holds less moisture than warmer air so pulling in some cool air has the effect of lowering the relative humidity of the interior greenhouse air.

How to control temperature in greenhouse?

The temperature in a greenhouse is affected by the amount of sunshine and ventilation. Greenhouses are designed to trap the sun’s heat. The temperature in a greenhouse can be controlled by opening the door or opening vents in the roof. In some cases, air conditioning could be used to bring the temperature down to a more tolerable level.

Temperature control is easy to automate with the availability of tools. You can link vents in the roof to a system of rods that open and close the vents in response to the temperature. You can even install a greenhouse heater for certain seasons.

For proper greenhouse temperature management, there are some things you should follow. One thing is to consider crop timing. Plants will develop faster as the daily temperature increases. Thus, cropping time, or the time from harvest until plants are marketable, shortens at progressively warmer temperatures. There is a greenhouse temperature difference between night and day since nights tend to be cooler. Greenhouse temperature at night consumes more energy because the sun is not available for heat and more energy is needed to provide artificial warmth especially during the winter season.

To keep the humidity levels down during winter season Pulling in the cold air into the greenhouse and exhaust some of the warm air. It may seem counterproductive but your plants will be healthier for it.

You should use these greenhouse temperature control methods to produce good crops. Growing crops at lower temperature tend to be higher quality especially if light is limited. During warm season it is easy for greenhouse effect temperature to increase but the greenhouse is being ventilated with fresh air drawn form outside to keep the interior air exhausted. Humidity is rarely a problem.

In some greenhouses you have to use certain methods to convince plants they are in a certain season. Some devices you can use are extra lights that imitate the sun during morning hours and late afternoon hours. You can also use greenhouse heaters to increase the temperature. All these devices can be controlled by timers so you don’t have to do it manually.

Tools for greenhouse temperature monitoring

There are specific tools for a greenhouse that can help you maintain it efficiently and with less hassle. One important tool is a wireless greenhouse temperature monitoring system. This tool allows you to track the temperature and humidity fluctuation on your greenhouse online. You can detect problems at an early stage and it works in real-time mode. Yes, technological progress has caught up with your greenhouse and a greenhouse wireless temperature alarm is indispensable if you want to keep a healthy greenhouse.

Greenhouses are artificial environments and they need proper maintenance and care at all times especially when you are growing off-season plants.

Another important tool is the greenhouse temperature alarm. This tool identifies problems such as power outages, temperature fluctuations, water damage, and intrusion. Some models even have a pre-set telephone number that notifies you of any untoward occurrence. There is remote access that allows you to call any time to monitor conditions.

You should also get a greenhouse temperature control system which provides dependable heating and cooling options for your greenhouse so the temperature will always be at an optimum level. You can control the temperature inside your greenhouse despite the outdoor weather.

You should also need greenhouse temperature sensors. These sensor monitors air circulation and can be placed on automatic ventilation systems like vented roofs, side vents and forced fans. This monitor will alert you if systems stop running or malfunction.

A greenhouse temperature gauge is a tool which lets you see at a glance the highest and the lowest temperatures over the past 24 hours. Checking this tool in the evening, lets you know how hot things got in the day while checking it in the morning tells you how cold the night was.

A greenhouse remote temperature monitor offers you even better control of your greenhouse and lets you see broad data about temperature. This tool lets you see temperature over a defined period of time. Temperature is recorded autonomously so it can be viewed and evaluated for various purposes.

Greenhouse temperature in summer

Greenhouses will be extra hot during the summer and you will be sweating a lot inside one of these controlled environments if you are ever working in one for the season. Greenhouses are a hobby for some since it allows you to have your favorite plants, fruits, and vegetable available all year round.

Greenhouse temperature regulation is important in summer season since most plants cannot thrive in extremely hot conditions. What is the perfect temperature for greenhouses? 27°C or 81°F is good enough to keep plants healthy. Anything above that will kill off your plants. Tomatoes, for example, have poor pollination and grows immature fruits as temperatures climb above 32°C (90°F) by day and 24°C (75°F) by night.

Greenhouse temperature and humidity control during the summer require a canny combination of shade, ventilation, and humidity. A smart way to keep ventilation in your greenhouse is to use air movers. These devices certainly help cool down your greenhouse to keep your plants healthy for the season.

Final Words

You have to keep the optimum greenhouse temperature for tomato plants to make sure they will grow healthy. The temperature should be 32°C (90°F) by day and 24°C (75°F) by night.

Greenhouse temperature for vegetables depends on the type of crop but growing crops at lower or cooler temperature produce better results. The plants have more branches and flower buds than plants grown warmer. It is so easy to monitor and control your greenhouse with a greenhouse temperature and humidity intelligent control system. Having a greenhouse temperature control vent makes it easier to control humidity in any season. Greenhouses are a great hobby for people who love plants and the availability of tools and technologies makes maintaining a greenhouse more efficient, hassle-free and fulfilling all year round.
