Color Light For Your Plants

As a gardener, it is vital to note that plants will grow well with most lights’ colors. Each color’s amount or intensity will be the larger deciding factor than the color of the light used for your plants.

The gardener is responsible for ensuring and monitoring the proper color of light while growing plants in the greenhouse, aside from the other conditions like temperatures.

Having the control over your greenhouse’s environment is its advantage, as you can create a surrounding suitable for your plants despite your location or the weather you are experiencing.


Best Color Light For Growing Your Plants

What color light would be the best for growing plants in a greenhouse? Gardeners often choose green, yellow and orange lights for growing plants in a greenhouse, thinking that these colors are from the same spectrum given out by the sun.

We are trying to mimic the ideal conditions that your plants require for optimal growth in a greenhouse.

Most recent studies show that your plants’ photosynthetic activity is actually in the spectrum’s blue and red frequencies.

If you want to have a beautiful and healthy yield, you’d like to use red and blue lights as these colors absorb maximum chlorophyll, beneficial for plants.

However, you must also understand that there are different types of lights and colors that you can use in a greenhouse for growing your blooming plants.

While blue and red are the best colors for growing these plants, a full spectrum LED grow light will be the ideal option for growing your plants in a greenhouse.


LED compared to fluorescent

What color light would be the best for growing plants in a greenhouse? When you use a fluorescent bulb, this emits blue lights that would help you attain bushier plants.

Fluorescent bulbs are also excellent when seeding your plants because they do not give off too much heat, which is very important to monitor when taking care of your growing plants in the greenhouse.

If you opt for a fluorescent lamp to ensure your plant’s growth, you may select between warm white and cool white (with more blue color in it).

But LED lights, more energy-efficient and long-lasting, uses wavelengths that fluorescent bulbs don’t use.

Moreover, an owner, farmer, or gardener finds it easier to choose the actual color spectrum with LED lights, which fluorescent bulbs can’t provide.

With this in mind, the following information will discuss each color and its different effects on your lovely plants as they grow in your greenhouse.


Blue color

While gardeners use the blue light, always remember that the emphasis is necessary on mixing it with other spectra of lamps.

Some plants can experience adverse effects from blue light, such as stunts in growth, as it influences the color, energy acceptance, and leaf thickness of your plants.

A minimum intensity of blue light is enough to help with your plants’ maturity and growth rate and minimize their total water loss.


Red color

Another influential color of light for growing your plants in a greenhouse is red. The color spectrum red works better if you combine it with blue to achieve well-developed and healthy plants surely.

The color red is helpful for your plant growth, for it plays a massive role in seed germination, expansion of leaves and stem, and during flowering stages of your plants.


Green color

Among the unique and beautiful spectrum of colors, gardeners tend to ignore the color green for their light because it has the least efficiency.

But according to studies based at Michigan State University, the color green is still useful in the photosynthesis and structure of your growing plants, especially in a greenhouse.

The green color light helps any greenhouses with thick top canopies so that the leaves staying in the lower part still receive sufficient green light on their own to participate in photosynthesis.


Light Intensity Vs. Color Of Light

Yes, the light intensity is more important than the color of light when growing plants in your greenhouse. Besides learning the color spectra, it is vital to note the next step, which is to realize the importance of light intensity while growing your plants healthy in the greenhouse.

In general, the higher the intensity level of the light for your plants, the higher the photosynthesis rate will be.

Keep in mind that adding grow lights in your greenhouse is crucial because greenhouse glazing lessens the light available by your plants for photosynthesis. 



Maintaining optimum and ideal conditions in your greenhouse can be challenging for some, but it is still very attainable for everyone.

Besides the proper conditions and temperatures needed for your greenhouse, note that the combination of blue and red lights is best for your growing plants because these colors are the most significant for your plant growth, stability, and structure.

Each color has a different but equally significant role for your plant’s health, so it is vital to learn the amount or intensity of light for each color your plants will need while growing in a greenhouse. 

Nevertheless, what color light would be the best for glowing plants in a greenhouse would either depend upon the plant or you. Thanks for reading and we hope you’d check on us again!

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.
