What To Know When Growing In A Greenhouse: 5 Factors To Consider


Seasons and planting zones

In general, you can be productive in the greenhouse year-round. You can start sowing the seeds in the spring, while some flowers and other plants will thrive well in the summer. The fall is also ideal for other crops, while winter frost is no longer a problem thanks to the adjustments you can do indoors.

However, different states and locations will experience various conditions, as well. For greenhouse growing, this is where learning the planting zones will be beneficial for you. What are the planting zones?

Every state has its USDA planting zone rating. Upon learning the planting or hardiness zone of your area, you can use this to determine if your chosen crops will thrive without problems. You will know the temperatures and rainfall you can expect on each planting zone, so it’ll be easier to select a cultivar or variety that’s ideal for your state before planting in a greenhouse. 


Temperature, humidity, and ventilation control

Now that you know your expected conditions and your plants and crops’ tolerance, you can adjust the temperature and humidity in the greenhouse accordingly. Every plant, harvest, vegetable, or flower will grow well in its optimal temperatures, so use the range and check in the greenhouse year-round. 

This task is as simple as adding a thermometer to make sure you’re getting accurate readings indoors. Once you have the numbers, you can use a heating or cooling system to adjust the conditions. For example, if your plants don’t do well during the winter months, proper heat adjustment will allow you to extend your growing season. 

On the contrary, a cooling system will help your plants tolerate the heat during the summer. If you fail to modify the temperature indoors, it will just follow the weather’s existing conditions. The beauty with greenhouses is that you will still have a say on how you can choose an economical option for temperature control. 

The control of humidity and failure to monitor it will cause a thirst for plants, diseases, and pests in the greenhouse. You can use misting to improve and adjust the humidity, while vents or a small fan for air circulation can modify ventilation. It would also be best if you change the humidity and ventilation according to the season. 


Lighting conditions

The light in the greenhouse is also as important as the temperature and humidity. Every plant has a specific lighting requirement, so study the basics of using growing light before planting. Plants conduct photosynthesis, and failure to achieve their lighting requirements will affect their growth and health. 

However, it’s not enough to only learn about lights. In some cases, you will have to minimize the plants’ exposure by strategizing the lights’ locations and even using a shading sheet for greenhouses to reduce sunlight. This is also the part where you have to adjust the lighting conditions depending on the season and if you want to encourage a specific stage of growth.


Watering systems

When it comes to choosing and using a watering system, your plants’ water requirements will dictate the proper practice. You don’t want to overwater or underwater the plants as both are detrimental to their health. In general, avoid sprinkling water on the leaves to prevent diseases and focus on hydrating the roots. 


Pest management

Pest management in the greenhouse is simple, especially with proper preventive practices such as an inspection to avoid contamination, pruning, humidity control, and cleanliness. However, don’t panic if you see pests, as this gives you enough time to address the issue. You can also read about the pests to expect on your plants to prepare beforehand.  



Using a greenhouse is rewarding in so many ways. However, are you aware of what to know when growing in a greenhouse? It would help if you studied seasons and planting zones, temperature, humidity, ventilation control, lighting conditions, watering systems, and pest management. 

It can feel overwhelming for a newbie gardener, but you’ll notice a trend with each factor. Every plant, crop, or flower that you’ll grow in a greenhouse has a specific set of requirements and conditions. Once you know them, you can adjust the greenhouse accordingly. 

Overall, preparation, planning, and willingness to learn will help with growing in a greenhouse. Read various manuals from university extensions and prepare solutions for the problems you might encounter. What you’ll get from a successful greenhouse will outweigh the effort you’ll give.

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.
