Do You Need Humidity Domes When Planting Seeds In A Greenhouse

You may ask, do you need humidity domes when planting seeds in a greenhouse? Not necessarily, but if you want optimum results, you have to. Well, starting to grow plants on your own might be easy, but we can’t deny that there are so many things that you need to consider.

When you begin planting in a greenhouse, there are things that your plant needs to survive. Some examples are the soil, temperature, enough sunlight, and humidity.

We want to have better results; precisely, a high germination rate when planting seeds—having a humidity dome does this magic for you. In case you’re wondering if you need humidity domes when planting seeds in a greenhouse, then this is the right article.

Humidity Domes When Planting Seeds In A Greenhouse

Is There A Need To Have Humidity Domes?

So, the main question is, do you need humidity domes when planting seeds in a greenhouse?

Seeds will still germinate without having a humidity dome, but to achieve a more pleasant result, you’ll need one. The purpose of this item is for you to save so much time when you want to grow seeds in a faster way.

Usually, humidity domes are made from plastic and they are placed on top of a seed tray or container that holds your cultivation medium like soil; trapping moisture in the air below the cover is its primary goal.

After having enough moisture, this stimulates seed germination. Humidity domes also vary in size, shape, and form. Some come with adjustable vents that control the amount of humidity trapped.


Does Humidity Domes Need Holes?

The vents’ holes are often found at the top, side, or anywhere that you wish to. Proper humidity is the key to healthy, growing seeds.

Having a hole for humidity domes is not necessary. Vent holes are the ones responsible for high humidity.

Remember that anything too much can be harmful. It applies to high humidity and can result in the growth of mold in the soil.

Meanwhile, lack of humidity can make the soil dry and eventually weakens the germination rate, leading to the death of seeds.

Having vent holes is better when you start to plant seeds that take a more extended period to develop.


Are Lights Necessary For Humidity Domes?

The answer is no. Seeds sprout independently. Seeds can develop in dark areas and even sunken deep below the ground and still survive. Gravity is the one responsible that decides in what direction the seeds are going to grow.

However, the rules will have adjustments after the germination process finishes. The basic needs of a plant will apply, and seedlings will already need light to live.

Providing only low levels of light for seedlings will force itself to stretch. After a long time, this will become unpleasant because seedlings will become long-legged from continuous stretching to look for a light source.

To avoid having this outcome, transplant your seedlings in a well-lighted area. Slowly adjust the exposure to heat, amount of water, and the condition of humidity.

White LED lights can be a great option when developing seedlings indoors after the germination process.


When Is The Right Time To Take Off Humidity Domes?

When seeds turn into seedlings, then that is the right time to take off humidity domes. The transformation process depends on the plant, and some take a few days to a few weeks.

Leaving the humidity dome for an extended period will serve as an opportunity for fungi, mold, and other unfavorable situations to happen.

Planting similar types of plants is another way to develop them all together.


Making Humidity Domes When Planting Seeds In A Greenhouse

Sure, you can buy anytime you want, but if you’re going to have a customized and low-cost humidity dome, you can make your version.

Here is an easy tutorial on how to make your crowns using available recycled materials at home

An easy process is to find any available containers or pots and fill out the gaps with good soil. The seeds should be planted accordingly.

Pour enough water into the ground to make it moist but remember not to overwater.

Making the plastic wrap as the cover to the pot is a great choice. Tie the wrap with a rubber band. You can do this method effortlessly and still create a working dome for your beloved seeds.

Another way involves the use of a plastic bag and a moist paper towel. The cultivation medium will be the paper towel instead of soil. Place your seeds in the paper towel and gently wrap it around them.


Benefits Of Humidity Domes

Not only a humidity dome speeds up the germination rate of the seeds, but it also protects your seeds from pests; a blackout dome made from existing crowns where only certain seeds can develop.



Through plants, we get to eat healthy and nutritious food. Having a humidity dome is unnecessary, but through this, developing your seeds will become quicker, saving you much time.

Do you need humidity domes when planting seeds in a greenhouse? Well, you can buy crowns, but making your version keeps you from finances and what you desire will come true as you can customize it.

We hope that you learned many things from this article. Good luck and make the most out of every moment!

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.
