Knowing When to Put Seedlings Under Light

Knowing when to put seedlings under light is a must for gardening enthusiasts who wish to grow their seeds indoors. If you don’t want to be like the countless others who end up getting frustrated as they grow through the planting process, you need to know when to incorporate light at the right time. While caring for a seedling can be a little challenging, seeing them thrive well can be an extremely rewarding experience as well.

Among the biggest challenges of growing plants from seeds indoors is the lack of natural light that gets through the seedlings. Light is important for the seedlings as it activates photosynthesis – a process where the plants convert solar energy into chemical energy which helps the plants produce their food. As the seedlings continue to establish their root system, they need all the light they can get for the nutrients they need.

Knowing When to Put Seedlings Under Light

When to Give Your Seedlings Light

While plants would very much prefer to grow under direct sunlight, there will always be a time where you’ll need to add supplemental light to support their growth. A grow light can be a perfect solution for you to give your seedlings the light requirements they need – especially when they don’t get enough sunlight from the windowsill. Fortunately, it’s not that difficult to know the best time to put your seedlings under the grow lights.

Light exposure should be done at the earliest time possible. According to green thumbs, the best time to give seedlings light is when the seeds have started to sprout. Once they break the soil, you want to give them all the light requirements they need as it’s the main thing that will drive them to make their food and flourish.

It helps to prepare the grow lights even before planting your seeds. This way, by the time your seeds start sprouting, all you need to do is to turn your grow lights on.


How to Set-Up Your Grow Lights

While grow lights are a great alternative to natural light, they will only produce great results if the owners use the right light and set-up. Here are some tips on how you can set-up effective grow light that will give your plants the light requirements they need:

Tip #1. Use a full-spectrum light

The color of the light also plays a role in the development of plants. For instance, violet-blue light helps with the plant’s photosynthesis, chlorophyll production, and growth, while red light encourages budding and flowering. When choosing the light for your plants, be sure to use a full spectrum light such as LEDs to make sure that your plants will be exposed to both colors and you can reap the benefits.


Tip #2. Hang your grow lights

As you put the grow lights together, you have to make sure that it can give enough light to all the seedlings. The best way to do this is to hang your grow lights overhead. This way it will mimic the sun and provide equal light to all the seedlings.


Tip #3. Use a timer

One of the best ways to ensure that your plants grow well is to give it a consistent amount of light. However, it’s sometimes easy to forget to turn the lights on or off, especially if you have other responsibilities to tend to at home. To avoid having to schedule your day around turning the grow lights on and off, consider using a timer that will automatically do it for you.

Benefits of Growing Seedlings in Hobby Greenhouses

You’ll be surprised to know that one of the best ways of making sure your seedlings will grow strong and healthy is by placing them in a hobby greenhouse. Having one offers a lot of benefits for your seedlings. Here are some of them:


Benefit #1: Weather protection

Among the many reasons why seedlings and plants fail to thrive outside is because of harsh weather conditions. Some of them cannot tolerate extreme dips or increase in temperatures and, as a result, some of these plants die. With a hobby greenhouse, however, you’ll be putting your plants in an enclosed space that will protect them from winds, frost, or extreme heat.


Benefit #2: Pest and predator control

Planting your seedlings in a hobby greenhouse gives you the chance to protect it from pests, moles, rodents, and squirrels. Since the area is enclosed using plastic films or screens, it can keep predators outside, thus, protecting your seedlings and plants from being consumed by wild animals.

Benefit #3: You can control the light and temperature

Seedlings need to be placed in certain temperatures for them to thrive. By having a hobby greenhouse, you can easily set up your grow lights and control the temperature giving your seedlings the optimal environment in which they can grow.


Final Word: Knowing When to Put Seedlings Under Light

Light plays a vital role in the development of your seedlings which is why it’s important to make sure that they get enough of it. Now that you have an idea of when to put seedlings under light, the next thing to do is to implement it and set-up your grow lights. If you do it right, you’ll be able to grow strong plants and enjoy high-quality harvests.

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.
