The Evolution of Indoor Planting Technology

Plants have been growing for years using conventional methods that require plenty of resources, including land, sunlight, manpower, and water. However, the external elements like rain, weather, sunlight, and humidity hindered the plant growth and needed an advanced technique to mitigate its effects.

Until the beginning of the 20th century, farmers began experimenting with protecting crops from these elements. They started by placing a simple small box in the ground and topped it off with a flat piece of glass to develop it into small-scale greenhouses. With this exciting indoor planting technology brought a steep learning curve to design optimal growing conditions for many plants.

The technology vastly supported farmers’ visions to grow crops without any soil. The technological advancement in hydroponics was followed by LED lights, where crops are given their own optimized environment in a controlled indoor system.

The introduction of indoor farming in the form of greenhouses meets the demands of a revolutionized agricultural demands by allowing crops to flourish in the environment as desirable to their growth stages.

The Rise Of LED Technology in Indoor Gardening

The paradigm shift from soil planting to indoor gardening brought LED technology into the spotlight. Artificial lighting was to make up for the lack of natural sunlight, offering numerous benefits that surpass conventional methods.

As indoor cultivation has become more popular, these facilities have discovered that LED lighting is their best option for optimum plant growth.

Forward-thinking growers learned that Switching to LED lighting is a smart way to lower energy costs and environmental impact and have better control over the light intensity.

LED lights and their spectral science revealed some fantastic benefits, such as producing more marketable crops overall, creating bigger yields per plant, and altering the wavelength of light to change the flavor of foods.

Understanding The Dimmable LED Grow Light:

What Are Dimmable LED Glow Lights?

As we all know, Sunlight has been a major source of energy that was dictating most plant growth for years, but as the development of Phlizonstore Dimmable LED technology steps into the industry, many growers moved  towards indoor cultivation.

These lights have opened many doors for energy-intensive industries, with an aim to maximize spectrum and coverage while reducing dangerous heat and wasted energy. Surprisingly, these lights meet crop's needs and help them thrive better to produce significant output.

Dimmable LED grow light seems to be a flexible and convenient lighting technology that allows the grower to handle the plant light settings, thus controlling the ambiance inside the plants’ growing room.

Through dimmable switches, you’re able to switch off sections of your light to change how it’s supposed to work with the plants.

Dimmable LED glow lights are a great replacement for halogen bulbs and incandescent in terms of quality of light, compatibility, and light output.

Being able to create and enhance the perfect atmosphere for your plant anytime- all cozy, warm, and bright- phlizonstore LED lights can help you achieve that.


The Technology Behind Dimming Mechanisms: Pulse Width Modulation (PWM) Vs. Analogue.

While manually adjusting your grow lights farther or closer to the plants, you can adjust light intensity to a certain degree, but this seems pretty  inconvenient.

However, LED grow lights with dimmable switches not only allow you to dim the lights but also offer you an option to alter the amount of white, red, and blue light emission.

This means you can adjust the light to the different needs of the various growth stages, such as increasing the blue light during the vegetative stage and the red light during the flowering stage.

When it comes to dimming LED lights, two main methods are involved: Pulse Width Modulation (PWM) and analog.

  • PWM: Despite traditional lighting, such as incandescent, this method is the most common and generates low-frequency output signals from high-frequency pulses. You can adjust the brightness level by regulating the percentage of the time the lights are off(0%) to the time they are on (100%).

For example, Suppose you have dimmed your lights to 30%; they will remain ‘on’ for 30% of the time and turn ‘off’ for the remaining 70%. This creates an optimal dimming effect without increasing or decreasing the voltage reaching the light.

  • Analog: A more straightforward approach to dimming. Analog refers to controlling the current to either dim or brighten the lights. Lowering the current will dim the lights; which at the other end, increasing the current will create a brighter light.


The Science Of Light In Plant Growth


LED grow light is an energy-efficient mechanism used as a supplementary light source for indoor plantations. However, the grower's hard work isn’t just about investing in these lights or overpouring his love for the crops; It begins with understanding the light intensity that will help growers grow more efficiently.

Importance Of Light Intensity And Spectral Distribution.

The application of light intensity and spectral distribution is crucial for plant growth and development, and it plays a vital role in the morphogenesis, growth, and metabolism of many biochemical pathways in plants. This is evident when plant cultivation is compared under different light environments.

When determining the effect of light on plant growth, there are three key areas to consider: intensity, duration, and exposure

  1. Light intensity refers to the brightness of the light; the more intense the light is, the more energy it contains.

Generally speaking, if plants are exposed to very bright light, they will tend to have a better branching structure with larger and dark green leaves, while in low light intensity, their branches will be spindly, and their foliage will be light green.

  1. Duration usually means for how long the plant is exposed to the light source.

This element is going to be crucial as it dictates many plants to complete the life cycle. When you allow the plant to be exposed to a longer duration, obviously, it helps them make sufficient food to survive and grow. However, know that plants need some darkness to develop appropriately so they should be exposed to light for no more than 16 hours daily.

  1. Exposure refers to the plant's distance to the light source.

Light when put too close to the plants or too far won’t do any good to them; instead they cause light stresses,  therefore it’s recommended to do the plant placement 12 to 18 inches away during all stages of growth and development.


How Different Light Wavelengths Influence Plant Health And Productivity

Do you want your indoor gardening to be all bloomy and flourish, if yes; then you need to know the light mechanism for different phases of plant growth. This will let you go through a comprehensive understanding of the light spectrum and the plant responses to a specific wavelength, while enhancing their development, quality, and productivity alongside.

 phlizon led grow light full-spectrum

Light as a source of energy  moves as an electromagnetic wave; what we usually see from our eyes is made up of electromagnetic radiation in a specific range of wavelengths between 400 and 700 nm.

The picture shown above reflects Blue and violet lights at the left with short wavelengths and more energy, while the other Red light at the right end has the longest wavelength and the lowest point. These color wavelengths have the most impact on the health of a plant.

  • Ideally, the 400 and 700 nm range of wavelengths are considered optimum for plants. Blue light puts its part in chlorophyll production, resulting in healthier foliage. Red and far-red light foster growth and flowering, which becomes helpful for long-day plants under short-day conditions.
  • As you see, blue color lies in the wavelength between 400-500 nm; this light has high energy and affects plants' leaf growth (also called vegetative or “veg” growth). If a plant doesn't get enough blue light, it will get weaken, with yellow streaks in the leaves instead of green.
  • Red Light in a range of 600-700 nm wavelength is called a low-energy light. This spectrum is essential for the plant's flowering and blooming. Deficiency in this range will invariably result in delayed flowering or a fragile plant blooming stage.
  • Luckily, If you own a large grow space surrounded by multiple lights,  you may need to dim your lights more often than if you’ve a small grow space.
  • Finally, some growers really like to dim their grow lights in the final few days before harvest, and others prefer to just dial down the intensity of the light at this time.

Plants primarily want blue and red light for photosynthesis. However, infrared light performs its part for flowering. Fluorescent lights vary in light colors. Those with cool-white bulbs produce primarily blue light and are low in red light, and they work well for foliage plants. Blooming plants require extra infrared light supplied by incandescent lights or unique horticultural fluorescent lights.

Through photosynthesis, light, especially blue and red wavelengths, provides this energy required for plant growth and development.

Similarly, Light regulates several morphogenetic processes through photoreceptors, including plant elongation, leaf expansion, stomatal opening, circadian clock, and flowering.

The light spectra influence both primary and secondary metabolism, affecting plants’ nutritional quality, carbohydrate and nitrogen metabolism, the production of flavor, color, volatile and aromatic compounds, as well as plant defense mechanisms.

Practical Applications: Setting Up Your Dimmable LED Grow Lights

Once you’re done getting your Dimmable LED grow lights from Phlizonstore for your indoor garden, the next step is to know how to set them up.

This would require determining what wattage LED dimmable grow light is,  the space available in the growing area, temperature/humidity levels in your growing room, the type of plants being grown, and the stage of plant growth.

If you got a growing space that has a higher number of plants, you”ll be needing more LED light setups. The light intensity should be examined, at the first place, when selecting the LED light for the operation. A standard 200W LED light is said to be sufficient for a yield of around 100 grams.

  • First, go with a well-ventilated location for your LED grow light, and don’t forget to see if it has enough room for the light and other necessary equipment.
  • Hang the LED grow light by use of a chain system or an adjustable rope. Make sure  it’s securely attached to the ceiling of the room or the support structure.
  • Connect the LED grow light to a power source by use of the provided power cord. Be mindful of the manufacturer's instructions given along to avoid overloading the circuits.
  • Set the timer on your LED grow light to provide the appropriate light for your plant's specific needs. For most plants, this will be 12-16 hours a day.
  • Monitor the light output of your LED grow light regularly and adjust the height and position to avoid burning or stressing your plants.


Benefits of Using Dimmable LED Grow Lights for Plants

By dimming your plant grow lights, It’s pretty evident that these lights would produce less heat, use less electricity, and cover less canopy area. But by dimming these lights, would they benefit the plant growing system? Well, yes. Very much so.

Its efficiency applies to converting electricity into valuable photons that alter the light spectrum. LED lights are designed to produce lighting at nominal wattage; turning them down means they no longer produce the spectrum they were built to deliver.

Pleasing light quality and efficient light output, Dimmable LED grow lights create an optimal indoor gardening space for your plants and you.

Below, you’ll understand how LED grow lights can assist you in getting the most out of indoor plantation

  • Dimmable LED lighting for plant growth lets the facility operator unprecedented control over all aspects of the plant’s environment, as indifferent to the Outdoor cultivation, which is subject to inconsistent amounts of sunshine and weather patterns.
  • During the warmer months of the year, turning down the lights to reduce their heat and ensure that your growing space doesn't become too warm can be handy with these lights.
  • Plants generate different forms of chlorophyll to varying wavelengths within the visible lighting spectrum (400nm to 700nm).  PhlizonstoreDimmable LED lighting for plant growth lets you generate the most desirable form of chlorophyll a plant needs at each stage of its growth cycle. Unlike HID and other forms of commercial artificial lighting, LED lighting gives the flexibility to manipulate the spectral qualities of the emitted light to coincide with plants' needs.

  • Dimmable LED grow lights are built to last up to 50,000 more than the HID lifetime of 10,000 to 18,000 hours.
  • The light output of most dimmable LED grow lights can be adjusted by 25%, 50%, 75%, and 100%. Integrating Phlizonstoredimmable LED grow lights into the plant growing system allows growers to Regulate the light levels precisely for crops, thus contributing to higher yields
  • LEDs are highly adaptable to various lighting applications as they can be of different sizes.


 Monitoring & Adjusting Light IntensityThe mechanism of light is one crucial aspect for plant growth and development, as it defines the process of photosynthesis. Know that either extreme i.e. Too much and too little light causes light stress in plants, harming their growth and productivity.

Light stress in plants occurs when the balance between the light intensity and energy absorbed by the plant is disrupted, so regular monitoring is necessary to ensure you get the optimal results.

By understanding plant responses to light stress, growers and farmers can develop strategies to optimize plant growth and increase crop yields. Several signs can indicate if your plants are experiencing optimal light conditions or light stress.
