How To Regulate Heat For Cool Weather Crops In A Hobby Greenhouse

How to regulate the heat for cool weather crops in a hobby greenhouse involves knowing in-depth advice on the steps on how to do this. During the summer, you have felt the intense heat of the season, particularly when you are spending more time inside the greenhouse.

Temperatures in this environment can reach several degrees more than when you are outside, and even during the winter, but sunny days within the growing season in this effect can influence plants and even more gardeners. So what should you do?

How To Regulate Heat For Cool Weather Crops In A Hobby Greenhouse

First off, know that greenhouses or hothouses should be able to house both warm-loving crops — melons, tomatoes, and cucumbers — and cool weather crops. However, even they have limits too, and for instance, you have tomatoes in temperatures that may climb up to 90 degrees Fahrenheit (32 degrees Celsius) during the day and up to 75F (24C) at night.

Thus, the need for cool weather crops.

What Are Cool Weather Crops?

There are several crops that can tolerate the coldest of weather, and you can have the soil where to plant early spring vegetables that can be categorized as cool weather crops. 

They are very different because the cool-season crops must be cultivated so when their maturity peaks as the weather are cold and prior to the summer’s heat. As the warm weather arrives, many of the crops would usually “bolt” or run to seeding prematurely. 

The crops may flourish in temperatures lower than the recommended temperature, so being able to plant the seeds or transplanting at the right time can aid in ensuring you will get the healthiest harvests.

It is thus recommended to grow cool-season crops such as potatoes, broccoli, or lettuce to receive your early start for the spring garden. Such crops will stay strong in cooler temperature ranges and are ideal as spring plants. Knowing what you must grow when planting seeds, alongside tricks, should assist in ensuring spring vegetables thrive for the entire year’s seasons.

They could include:

  • Lettuce
  • Bean
  • Cabbage
  • Mustard
  • Okra
  • Runner Bean
  • Tomato, and more

Ways To Regulate Heat For Cool Weather Crops In The Hobby Greenhouse

The steps on how to regulate the heat for cool weather crops in a hobby greenhouse can be very easy.

Knowing What You Should Grow

There are several crops that are able to tolerate the coldest of weather and the soil approaches and may be cultivated as early vegetables in the spring. Your cool-season crops must be planted right with the correct temperature at an estimated lower than 22 degrees Fahrenheit. 

Ventilating A Greenhouse

Another step is to ventilate the greenhouse to regulate the heat for cool weather crops. The greenhouse can offer the best of the environment all-year-round, but ventilation is still important because, in this way, you will be able to keep them producing their finest.

Take note that temperatures over 27 degrees Celsius may cause damage upon plants, so it is important to prepare your thermometer so you can monitor the situation well. During sunny days, you can head as early as you can open the vents and the doors, so the nights are warm for the crops. There is also equipment that can prevent the entry of distracting wildlife.

Hardy Crops And Semi-Hardy Crops

Then, you have the concept of hardy crops and semi-hardy crops. Within the category of cool-weather crops are these entities characterized by the environment they can grow with. 

For instance, hardy vegetables are able to tolerate the cold temperatures, as the seed germination happens in colder soil. Not only this, but the seedlings will also survive the heavy frost. You may be able to cultivate the seeds and transplant these three weeks prior to the date of the average last frost in the spring.

Plus, they will also grow in temperatures during the daytime as low as 40F (four degrees Celsius). 

On the other hand, your semi-hardy vegetables are your cool weather crops that can withstand the light frost. To regulate temperature for these, you must have a minimum daytime temperature from four to 10 degrees Celsius, and they must be sown as early as two weeks prior to the average frost in spring.

Preventing Water Stress

Thus far, the most effective tools that plants are known to use is transpiration or referred to as the moisture loss through the stomata or the leaf pores. The loss of moisture may cool down the leaf surface in a similar way that people sweat. 

It also reduces the ability of the plants to sweat, and may, in turn, wilt. By offering the right moisture for the plants to draw up from the lower levels, they may remain cool. 

This involves looking for signs of heat stress, such as drying out foliage, leaves getting scorched, and wilting plants. Diligent application of these tips must prevent the side-effects of water stress successfully. 

How Do You Keep A Greenhouse Cool In The Desert?

Now when the hobby greenhouse mimics the environment of the desert, among the common ways to keep it cool is through utilizing the cooling walls. While your vents can contribute, they may not offer the right cooling, and this is where swamp coolers help, given the lower humidity revealed in deserts.

Why Have A Hobby Greenhouse

Not every greenhouse is created equal, and thus, you must be able to have the hobby greenhouse with you for their particular purposes. Your hobby greenhouse is not as difficult to manage as your commercial greenhouse, so you should try having one in your vicinity for gardening.

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.
