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:

 

Insulation

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.

 

Ventilation

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

 

Shade

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 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.
