Do You Need Humidity Domes When Planting Seeds In A Greenhouse?

If you believe you know enough about greenhouse cultivation and harvesting, think again. Even the advanced greenhouse owner may not yet fully understand certain concepts such as humidity domes. Today’s focus is on heavy-duty equipment known as your humidity dome

Do you need humidity domes when planting seeds in a greenhouse? We will find out in this edition of the blog, with answers to the most frequently asked questions from planting enthusiasts.

Do You Need Humidity Domes When Planting Seeds In A Greenhouse

 

Humidity Domes Defined

In greenhouse gardening, humidity domes are structures or add-on equipment made of plastic, which sits on top of propagators, as well as seed trays. These are domed to let seedlings grow taller, and the material is more than just the aesthetics. 

The plastic is flexible and low-cost enough for the dome to be able to increase the humidity and temperature levels of the interiors. So, if your greenhouse provides the right temperature for these herbs, crops, and plants, the humidity dome will add to this benefit. 

Successful germination has a variety of temperature requirements, with the ideal temperature between 50 to 65 degrees Fahrenheit on average. The domes are intended for use indoors since most homes may not be this warm. The presence of such tools will manage and stabilize temperature levels, as well as humidity for the ideal growth. 

Should I Use A Humidity Dome On Seedlings?

To avoid confusion, take note that humidity domes are for gardening, but not for all applications. Meaning to say, as accessories, without using them, will give you the alternatives to still have the best produce. If you ask if you need humidity domes for seeds, the answer is no. The seeds may germinate without this, but the dome may also be used to improve germination rates for these seeds. 

They can also improve on the time and minimize the effort needed to keep the soil in the moist conditions for germinating the seeds. 

Does A Humidity Dome Need Holes?

Frankly speaking, humidity domes do not require holes. The dome’s purpose has always been to trap air moisture beneath the cover, thereby increasing humidity. 

There are cases when the dome’s vent holes will tell you if there is too much humidity. High humidity may lead to the growth of molds in the soil or in your seedlings. These may cause the holes in the humidity dome to be more attractive when you are planting seeds that take more extended periods of time to germinate. 

These holes are often spotted on top or the sides of the humidity dome, but may be placed elsewhere should you want to make these into your customized vault. Getting the right levels of humidity balances the act, in such a way that it warns against too high of the moisture in gardening. 

On the other end of the spectrum, less humidity may result in the drying out of the soil, disrupting your seeds, and reducing the rates for germination.

Will Seeds Germinate In A Cold Greenhouse?

Greenhouses are allowing gardeners and farmers to manage the humidity and temperature required for propagating the seeds and letting them grow. Since you have a controlled environment, the gardener may begin seeding anytime. This is one of the advantages of greenhouses. 

However, if you start with the process, wherein you take a look at transplanting into gardens outdoors for the spring, then you should get started with the seeds in the greenhouse at most, eight weeks prior to the “last expected frost date” in your area.

To succeed even further, there are seeds that must not be germinated in temperatures around 80 degrees Fahrenheit. The greenhouse’s temperature must also be carefully monitored. Greenhouses are warm in the day, when the sun is up, but may get cooler into the night. Always visit other resources for more details about these specific guidelines.

What Temperature Should A Greenhouse Be At Night?

Seventy-five degrees Fahrenheit or 24 degrees Celsius by night (90 degrees Fahrenheit, or about 32 degrees Celsius by day) — this is the advisable temperature that greenhouses must be. The temperature for vegetables may depend on the type of the crop, but having these at cooler temperatures has been proven to showcase better outcomes. 

Mainly, your plants will grow more branches and floral buds than plants grown in warmer temperatures.

To fully understand and to help you decide whether you must have the humidity dome in your gardens, it is excellent to know about the humidity. In gardening, this pertains to the presence and percent water vapor in the air, which directly affects levels of moisture in the greenhouse. 

Do you need humidity domes when planting seeds in a greenhouse? Humidity is one of the most important concepts to learn in gardening and horticulture since this will critically affect the outcomes of the crops.

With greenhouses, it will be easier to work with humidity levels because of the opportunities for customization it has for every gardener. You can choose from various sizes of the structure, depending on what you need. The right greenhouse protects your plants from changing weather patterns, strong winds, low temperatures, ground frost, and more.

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.
