What is Grow Light?

A grow light is an electric light that can help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated. Outdoor conditions are mimicked with varying colour temperatures and spectral outputs from the grow light, as well as varying the intensity of the lamps. Depending on the type of plant being cultivated, the stage of cultivation, and the photoperiod required by the plants, specific ranges of spectrum, luminous efficacy and color temperature are desirable for use with specific plants and time periods.

Advantages of LED Grow Lights

Economic electricity consumption

LED grow lights utilize up 50% of the energy that HPS systems use and some experts anticipate even a higher LEDs efficiency in the near future.

Longer lifespan

LEDs have a longer life span in comparison to the HPS lights; for the comparison’s sake, the HPS lamps can last for 1 year while the LEDs might last even up to 8 years (which translates into 50 000 hours of use).

Smaller spaces convenience

As the LED grow lamps can be set closer to the plants, the growing space does not need to be extremely high or wide.

Fire safety

As LEDs do not become very warm in comparison to the conventional HPS lamps they are safer to use.

Energy efficiency

With LED grow lights it is possible to optimize the spectrum by concentrating energy on wavelengths (colors) that are most beneficial for each application and plant. In addition, reduced heat production allows putting LED fixtures closer to plants ensuring less light is lost elsewhere.

Dimming

While the majority of HPS lamps use the full light intensity, LED grow lights can dim even with a remote control or via an app and therefore are easier to handle, apart from consuming less power.

Better crops

Various trials have shown that LED grow lights produce better crops in terms of plants getting bigger and growing faster, compared to the HPS lights. Additionaly, LEDs can be made with a spectrum aimed at a specific goal such as anthocyanin accumulation, flowering inhibition, enhanced rooting etc.

More environment safety

Due to the fact that less heat is emitted and that UV light can be added in LED lamps, there is less chance for bacteria and mold formation which subsequently means less pesticides and less environment pollution.

What Color Grow Light is Best?

The light spectrum ranges through red, orange, yellow, green, blue and violet. The colors at the far ends are most useful to plants but all colors are absorbed to some extent. Different colors serve different purposes which I will outline below.

Blue light (and for the most part violet) is extremely important as it is how our plants get chlorophyll and therefore grow and strengthen their foliage.

Red light is needed for flowering varieties. You must be cautious when using this as too much red light can kill your plant which is why a lot of grow lights offer a mix of both red and blue so your plants are getting all their needs met.

Green and yellow light is said to have minor benefits when it comes to germinating seeds but otherwise is not essential to your plant.

Types of Grow Light

LED Grow Light

It has the characteristics of adjustable spectrum, which can adjust the light intensity and light ratio according to the different growth stages of plants. LED lights also have the advantages of high energy efficiency and low heat generation.

High Pressure Sodium Lamps

Widely used in commercial greenhouses, it provides strong red and far-red light, which is suitable for the flowering and fruiting stages of plants. High pressure sodium lamps have less blue light, which is not conducive to the leaf growth of plants.

Fluorescent Lamps

Economical and affordable, suitable for beginners and small-area planting. Fluorescent lamps have a narrow spectrum range and may not be suitable for the needs of certain specific plants.

How to Choose Grow Light

When choosing a grow light for your plants, there are a few factors to consider to ensure that your plants receive the right amount and type of light for optimal growth. Here are some tips on how to choose the right grow light:

Light intensity: Different plants have different light intensity requirements. Make sure to choose a grow light that can provide the right amount of light for the specific plants you are growing. You can measure light intensity in terms of lumens or lux.

Light spectrum: Plants require different light spectrums for different stages of growth. Blue light is ideal for vegetative growth, while red light is better for flowering and fruiting. Look for a full-spectrum grow light that provides a good balance of blue, red, and other essential wavelengths.

Energy efficiency: Choose a grow light that is energy-efficient to save on electricity costs. LED grow lights are a popular choice as they consume less energy and produce less heat compared to traditional HID lights.

Size of the growing area: Consider the size of the area you need to cover with the grow light. Make sure to choose a light that can adequately cover the entire growing area to ensure uniform light distribution.

Durability and lifespan: Look for a grow light that is durable and has a long lifespan. This will help you save money in the long run as you won’t have to replace the light frequently.

Budget: Set a budget for your grow light purchase and choose a light that fits within your budget while still meeting your plant’s needs.

Difference Between Grow Light and Ordinary Light

The main difference between grow light and ordinary light lies in their design purpose, spectral characteristics and light energy utilization efficiency.

Design purpose: Grow light is specially designed for plants and aims to stimulate plant growth by emitting electromagnetic spectrum suitable for photosynthesis. They are mainly used in applications where there is no natural light source or supplementary light is needed, such as extending the time that plants receive light in winter. In contrast, ordinary lighting fixtures are mainly used for lighting people or as decoration, and are not specifically designed for plant growth.

Spectral characteristics: Grow light is made according to the principle that plants use sunlight for photosynthesis. There are two main types on the market: full spectrum and red and blue spectrum. The spectrum of full-spectrum LED grow light is mainly concentrated in the visible light band of 400nm~720nm (except the green light band), while the red and blue spectrum grow light is concentrated in the red light band and the blue light band. These spectra are essential for plant growth. The spectrum of ordinary lighting fixtures is not as concentrated as that of plant growth lamps, and varies from manufacturer to manufacturer, resulting in poor effect on plant growth.

Light energy utilization efficiency: Due to the design and spectral characteristics of plant growth lights, they can more efficiently convert electrical energy into light energy that can be used by plants. This means that for the same kilowatt-hour of electricity consumed, grow lights can allow plants to absorb and utilize light energy more efficiently, thereby promoting growth. In contrast, when using ordinary lighting to supplement plant light, a lot of light energy that is not effective for plants is wasted.

Common Mistakes of Grow Light

Grow Light is too close

Watch out for signs that your grow light is too close to your plants foliage, such as brown leaves or even chlorosis. Identifying whether a grow light is too close to a plant is crucial for the plant's health. Raise the light source or reduce the light intensity to prevent damage.

Not Cleaning Grow Lights

Dust and debris can accumulate on your grow lights, reducing their efficiency and compromising its thermal efficiency. To keep your light shining at its best, turn it off, let it cool, and then gently wipe it off with a soft cloth.

Overwatering

Overwatering can be a common issue when using grow lights. Ensure you follow the appropriate watering schedule for your plants, as they may require less water when growing indoors.

Not Rotating Plants

Rotate your plants regularly to ensure even light exposure on all sides. This prevents one-sided growth and promotes balanced development.

FAQ

Q: Can any LED light be used as a grow light?

A: The best photosynthesis wavelengths on the visible light spectrum occur in the blue range (425 to 450 nanometers) and the red range (600 to 700 nanometers). Regular LED lights, on the other hand, lack many of the wavelengths needed for plant growth; the light they produce is only good for illumination.

Q: What is the difference between grow light and regular light?

A: LED grow lights and standard LED lights both produce light, but they differ in the breadth and intensity of the spectrum they emit. LED grow lights generate a broader spectrum, usually within the 400-700nm range, encompassing blue (400-500 nm), green (500-600 nm), and red (600-700 nm) light.

Q: Can you use a regular lamp as a grow light?

A: Typically, incandescent and halogen lights are not recommended as grow lamps because, while they do often offer full spectrum lighting, they operate at a very high temperature that can easily damage foliage. They are also inefficient in terms of energy usage, and are being phased out by governments worldwide.

Q: What is the purpose of grow lights?

A: These growing lights are specially designed to substitute natural sunlight, stimulating photosynthesis and providing the right color spectrum where the plant can grow and flourish. With the right fixture or bulb, you can have delicious tomatoes in the dead of winter or award-winning violets year-round.

Q: Can you turn any light into a grow light?

A: Yes. You can use a regular lamp or standard LED light as a grow light if there is a shortage exposure of lights in your indoor garden.

Q: How many hours should you use a grow light?

A: Place grow lights within a foot of the plant. Give plants at least 12 to 14 hours of supplemental artificial lighting; do not run them around the clock. Plants need a daily rest cycle. A high-quality, full-spectrum grow light, when used correctly, can substitute for sunlight.

Q: Can daylight bulbs be used as grow lights?

A: Grow lights should be as similar as possible to sunlight, so lamps with the colour daylight white are particularly recommended. Lamps with 1A or 1B in their specifications can also be used as grow lights.

Q: Should I leave grow lights on all night?

A: It is important for Plants to have some hours with no 'sun' light, and you should not leave your Grow Lights on 24/7. The plant will become stressed, and it can lead to stunted growth and can create mutations. The plant will also be weak and it's ability to produce flowers and or fruits will be greatly reduced.

Q: Do plants grow faster with grow lights?

A: Yes for sure. LED Grow Light is proven to have the ability to grow the plant faster and healthier than some traditional methods such as HPS lighting.

Q: Can I use my LED lights as grow lights?

A: You can use regular LEDs but you'll get better results with LED grow lights. LED bulbs and strips usually produce white light, which is helpful for general plant growth. However, plants really need blue and red light to thrive.

Q: What color grow light is best?

A: Blue: This is the most important light for plant growth. It is easy for chlorophyll to absorb and convert into energy. Red: As the second most important wavelength, red light is incredibly potent for plants when combined with blue light. Orange: Similar to red light, but less effective.

Q: Do grow lights use a lot of electricity?

A: The grow light wattage required to delivery a good yield will range from 400 to 650 watts, depending on the technology used. Therefore the power consumed by your grow light is about 80-90% of the total used in the grow room (excluding air conditioning).

Q: Can any type of light be used as a grow light?

A: There are three main types of light you can use in your grow light: incandescent, fluorescent and LED. Let's start with the weakest option. Incandescent lights are the cheapest but they also are the least efficient and have a high heat output.

Q: Do grow lights give off UV rays?

A: Yes, many LED grow lights emit UV rays. Although overexposure to UV radiation can cause cancer, in small amounts, UV exposure is beneficial for both humans and plants, stimulating vitamin D production in people and robust growth in plants.

Q: Can I use fluorescent lights as grow lights?

A: Using fluorescent garden lights to enhance plant growth allows you to grow a host of plants in an interior space. Standard indoor lights do little to influence photosynthesis, while using fluorescent lighting placed closely to the top of the plants can help drive this important plant process.

Q: Is too much grow light bad for plants?

A: However, plants require some period of darkness to properly develop and should be exposed to light for no more than 16 hours per day. Excessive light is as harmful as too little.. When a plant gets too much direct light, the leaves become pale, sometimes burn, turn brown and die.

Q: Can I use an LED ring light as a grow light?

Q: Can anything be used as a grow light?

A: A regular light bulb can help plants grow, but the results might not be as satisfactory as those provided by grow light bulbs. That's because grow light bulbs emit a full spectrum of light that plants need to grow and thrive, something which regular light bulbs fail to do.

Q: Can plants burn under grow lights?

A: And while using a grow light can be beneficial, they can also burn plants if they're used improperly or placed too close to them.

Q: Do grow lights have to be close to plants?

A: As an unofficial rule of thumb, many growers work on the basis that: You need 20-40 watts of power per square foot. Lower wattage LEDs of around 200 watts should sit between 12-20 inches from the top of the plant. Higher wattage LEDs of 1000 watts and above should sit between 36-46 inches from the top of the plant.
