How to Measure Air Temperature in a Greenhouse

Knowing how to measure air temperature is extremely important for those who are trying to grow the healthiest greenhouse plants. If you’re a gardening enthusiast who intends to provide their plant babies with the best growing conditions, then today’s your lucky day.


How to Measure Air Temperature in a Greenhouse

The Invisible Particles in the Air

In case you’re not aware, various combinations of two or more atoms make up the gas molecules that are present in the air. While these molecules aren’t visible to the naked eye, know that they’re constantly in motion at high speeds. As these invisible particles move, they tend to collide with the area’s solid surfaces, as well as with one another.


What is Air Temperature?

The air temperature tells you the measurement of the average random motions of the atoms and the molecules. When the molecules have more energy of motion, more heat is produced and the air temperature that you feel is higher.


What Instrument is Used to Measure Air Temperature?

You need to use a thermometer in order to measure the temperature of the air. In most cases, thermometers may look like a calibrated glass rod that has a very thin tube inside it.

If you look closely, you’ll see that a liquid is placed inside this tube. This liquid could either be mercury or red-colored alcohol. A reservoir that looks like a bulb that’s located at the base of the thermometer is responsible for supplying the liquid inside the tube.

Furthermore, as the liquid substance of the liquid substance rises, it expands. When this happens, the liquid rises up inside the tube. Since the glass rod is marked with a scale that could either be in degrees Celsius or in degrees Fahrenheit, you’ll be able to determine the measurement of the air temperature.


How to Measure Air Temperature: The Basics

Since a thermometer works to measure its own temperature, you need to place it in the shade when you measure the air temperature. Doing so will allow the thermometer to reach thermal equilibrium with the air molecules that surround it and measures that specific temperature.

Placing it under direct sunlight will heat up the liquid and give you a reading that’s considerably higher than the true temperature of the air. Doing so will only cause the thermometer that’s placed under the light to measure its own temperature instead of the air temperature. Should you measure the temperature outside, you need to give it several minutes to adjust to the air temperature outdoors.


Is it a Good Idea to Grow Plants Inside a Hobby Greenhouse?

Growing plants inside a hobby greenhouse is one of the best decisions that any greens aficionado can ever make. Although setting it up may involve a large cost, the benefits of greenhouse gardening will far outweigh your initial investment. If you’re still not convinced that growing your plants in a hobby greenhouse makes sense, perhaps this list of benefits might just change your mind:


You can grow more plants and extend their growing periods

Countless gardeners out there decide to turn to greenhouse gardening in order to grow more plant varieties and experience extended growing seasons. Since a hobby greenhouse allows you to control the climate inside its enclosed space, you’ll be able to grow tropical plants even if you live in areas where the weather is mostly cold. Conversely, if you live in the tropics, having your own hobby greenhouse will also enable you to grow a much greater variety of vegetables, plants, herbs, and flowers.


You’ll get to save more money on produce

Setting up your own hobby greenhouse will make it more convenient for you to grow your own food. Furthermore, you’ll have the freedom to create the best conditions that will position you to harvest a greater yield of produce. This will include foods that are typically out of season.


You’ll keep those pesky pests and animals out

Traditional outdoor gardeners are always confronted with the constant threat of destructive bugs and animals. It’s not unusual for their delicate plants to be ravaged by bugs that include aphids, cabbage maggots, caterpillars, cutworms, Colorado potato beetles, Mexican bean beetles, flea beetles, tarnished plant bugs, Japanese beetles, scales, raccoons, rabbits, deer, and other critters. A hobby greenhouse can serve as a protective barrier against pests and animals that will only put all of your gardening efforts to waste.


It protects your plants from inclement weather

You can eliminate the need to make emergency preparations to protect your plants from harsh weather conditions that include strong winds, heavy rains, blizzards, and hailstorms if you grow your plants inside a hobby greenhouse.


Have your personal backyard oasis

It doesn’t matter if it’s snowing outside – you can still enjoy being around your precious plants if you grow them in a hobby greenhouse. Just imagine yourself stepping into your own personal tropical oasis that’s filled with your growing and thriving plants.


The Takeaway

Now that you know how important it is to learn how to measure air temperature, you can easily manipulate the climate you subject your plants in. Should you decide to take your gardening experience to the next level, invest in a hobby greenhouse, and discover its full range of benefits!

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.



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.
