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.

 

Summer

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

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

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

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

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.

 

Damping

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.

 

Winter

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.

 

Conclusion

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 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.

 

Conclusion

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.
