Led Grow Lights: Buying Guide

LED lighting is the latest technology among indoor marijuana growers. This technology has proven to be very effective as far as growth and yield are concerned.

A light source that has a full spectrum of the Sun in it, but also has higher nanometer ranges of colors for both veg and bloom stages.

Full-spectrum LED grow lamps can enhance photosynthetic properties greater than any traditional grow light.

You can embrace this technology today by choosing a model that works for you. Here are important factors to consider.

Wavelengths

Cannabis plants use more blue and red wavelengths for photosynthesis than any other wavelengths.

Top-of-the-line full spectrum LED grow lights allow you to pick the ideal wavelengths in the full spectrum instead of a specific wavelength.

Some of the wavelengths that are crucial for indoor cannabis growing within the 400 to 740 nanometers range are:

• Red – 620 to 630 nm, 655 to 660 nm
• Blue – 440 to 450 nm, 450 to 460 nm
• Orange – 605 to 610 nm
• UV – 380 to 410 nm
• Far Red – 730 nm

Light Quality

You may have a full spectrum LED grow light that gives your plants all the necessary wavelengths. Are your cannabis plants receiving all the wavelengths?

Marijuana plants are capable of sensing UV to infrared wavelengths. This refers to the photo-biologically active radiation (PBAR, which ranges from 280 to 800 nm).

The visible spectrums (400 to 700 nm) also referred to as photosynthetically active radiation (PAR) is useful for photosynthesis.

The blue light spectrum ranges from 400 to 460 nm. The blue spectrum has fairly high energy. The wavelengths in this spectrum have pronounced effects on cannabis plants.

The blue spectrum normally promotes germination.

The red spectrum is resourceful at regulating growth as well as the development of your indoor marijuana plants.

The red light promotes cannabis flowering as well as fruiting. Far-red is essential for phytochrome recycling.

Light Intensity and PPFD

• Intensity

Light intensity influences the way your cannabis plants grow. If you grow your marijuana in low light intensity, they will tend to be spindly.

However, cannabis plants grown in a bright light would tend to be healthier. They would be shorter, thicker and with dark green leaves.

According to our evaluations, the light intensity your plants get depends on the nearness of the LED grow light to the plants.

Light intensity usually decreases rapidly as you increase the height of the lamp.

• PPFD / PAR

The PPFD is the number of photons in the PAR waveband that are incident on your cannabis plants. The PPFD is extremely important for indoor marijuana growing.

PPFD vary for the height of the lamp. For example, a given LED grow light may have a value of 594 μmol/m2s at 24 inches and 2172 μmol/m2s at 6 inches.

Wattage

Wattage has been used by indoor growers to establish the power of an LED grow light. Wattage is directly related to the coverage area.

For example, a 400W unit will flower a roughly 2 by 2, a 600W will flower a roughly 3 by 3 and a 1000W will flower a roughly 4 by 4 grow space.

However, the wattage draw is not the same as light intensity. A fixture will emit more light, depending on how efficient it.

You may find a 1000W full spectrum LED grow light that emits more useful light than a 1500W fixture at a height of 24 inches.

According to our inferences, wattage draw only gives you a general idea of how powerful a given full-spectrum LED light is.

Coverage Area

You can only be able to choose a quality to grow lamp if you know the dimensions of your grow space. You don’t want to invest in the wrong product.

Common size grows spaces for indoor marijuana growing include a 3 by 3, 4 by 4, and 5 by 5 feet growing area.

Large Full spectrum LED grow lamps may only cover a 4 by 4 to a 5 by 5 grow area. In fact, the only handful of models you will come across can cover more than a 5 by 5.

This is so since it is nearly impossible for an LED grow lamp to fully cover the corners and edges at a good light intensity.

In most cases, we recommend that you buy units with daisy chain function. This would allow you to add more fixtures of similar rating in order to increase coverage.

Most manufacturers will have recommendations for maximum and core coverage. In this case, core coverage refers to the area that receives optimum illumination.

Phase of plant growth and Spectrum

The phase of plant growth is very important when choosing the LED grow lights. If you are not looking for a specific phase and want a light to suffice through all the growing stages then you need to choose a full spectrum LED grow light.

Now full spectrum grow lights are available in a wide range of band options. The best ones or the ones that will promote development and growth from germination to flowering are the ones that have a balanced ratio of red, blue and white lights along with a share of UV and IR rays.

The best ratio of red to blue is 9:1. Some LED units have dimmable knobs to control the intensity of the lights while others are equipped with switches to alternate from VEG and Bloom stages.

Switching both of them together will give a full spectrum light. The PAR/Lumen value is also essential in determining the penetration value of the light. The PAR value is determined in accordance with the height. The higher the PAR value the better it is.

HID equivalence

The power of the HID light which can be replaced by the LED unit is extremely important. This helps you choose as to what strength of LED you need to buy.

The numerical value expressed at the end of an LED model is not the HID equivalence and consumers are often mistaken by it. For eg. V1200 refers to the total LED wattage or the wattage of an individual LED multiplied by the number of LEDs though the HID equivalence of V1200 is 1000W.

LED

The quality and the make of the LED chip along with the individual power and the technology makes an important mark in the LED grow light unit. Most high end LED grow lights use Bidgelux/Epileds LEDs or Epistar LEDs.

Some LED grow lights use a double or dual chip technology wherein a single diode is replaced by two diodes together. They are almost twice as brighter and better. Some LED chips have a Zener protector attached to them to enhance the durability of the product.

The protector eliminates the risk of breaking the circuit when a single LED is not working and hence the remaining unit still runs when attached to one.

Electrical consumption

The electrical consumption of the LED grow lights are generally much lower than any HID unit, but you get LED units which have the same power and give the same yield but consume much less electricity. Going for such a model will help in lowering the running cost.

Heat Dissipation

Though the heat generated by LEDs are much less compared to any other kind of grow lights, even then the heat generated has to be successfully dissipated or else it may burn and disrupt the LED circuit and also increase the temperature of the growing environment and affect plant growth. Too much heat can even burn the plants. Most LED grow units have high grade aluminum heat sinks and cooling fans to take care of this factor.

Price

The cost of high-quality full-spectrum LED grow light is also an important consideration for indoor cannabis growers.

This is so since these fixtures can be quite expensive. But, the cost of these fixtures is going down, while performance and efficiency are going up.

Good quality light can cost less than $100 to more than $2,000. The size, light output, and quality of parts determine the price of a fixture.

Frequently Asked Questions – FAQs

What is A Full Spectrum?

Literally, full-spectrum refers to light that contains all the colors of the rainbow. Usually, a full spectrum simulates natural sunlight.

What Color Light is Suitable for Seedling Germination?

The effect of the blue spectrum on plants is regulating growth. Therefore, this makes the blue light suitable for seedlings.

Why is PAR Important for Cannabis Growth?

Cannabis thrives in shorter wavelengths because they tend to deliver more energy. PAR outputs represent these shorter wavelengths.

Too high or too low PAR values may be damaging to your plants. Therefore, you need to maintain optimum levels that your marijuana plants need for photosynthesis.

What is the Ideal Height for Setting up an LED Grow Light?

Placement options differ from one brand to another. The recommended height for the veg is 20 to 26 inches, for the bloom is 26 to 30 inches, and for the veg plus bloom is 18 to 24 inches.

What Size LED Grow Light Should I Buy?

The size may differ to your grow area. For example, a 400W would be ideal for a 2 by 2 feet room, while a 1000W would be suitable for a 4 by 4 feet area.

However, the size/wattage draw does not determine the efficiency of the light. A 600W could deliver more light than a 1000W.

Sometimes it is even better to buy several small units and connect them using daisy chain function to achieve your desired coverage.

Are White LED Lights Full Spectrum?

White light can be generated by combining LEDs with different wavelengths, such as red, green and blue or yellow and blue.

Alternatively, white light can be created by coating blue LEDs with a phosphor.

In this case, the phosphor will absorb some fraction of the photons emitted by the blue LEDs and re-emit light with longer wavelengths through luminescence, creating white light.

The emitted spectrum can be adjusted based on the type as well as the amount of phosphor coating. Therefore, this is not a true white spectrum and not a full spectrum.

Are Full Spectrum LED Grow Lights Safe To Use?

You must consider several factors when talking about safety, including wavelength, intensity, and duration of exposure.

Intense light from very powerful fixtures will most certainly damage your vision. This is regardless of the wavelength the fixtures give.

The high light intensity can cause sunburns on your retinas and burns on your skin.

Most wavelengths within the visible spectrum are usually not harmful. But full spectrums that extend beyond visible light to include UV and far red are harmful.

Should I Be Worried About Hazardous Materials in LED Grow Lights?

Originally, LED fixtures were said to contain hazardous materials, such as mercury. But that is a myth nowadays.

According to research, LED lights are said not to be hazardous with an exception of low-intensity red LEDs that release a miniature amount of lead.

Conclusion

There is no better way of boosting your indoor cannabis growing than using a good quality full spectrum LED grow light.

Unlike traditional fixtures, full-spectrum lights ensure your plants receive all the useful wavelengths from UV to far-red.

Modern designs come with two modes of operation: vegetative and bloom. A true innovation in indoor lighting for optimum growth and higher yields.

The best of these lights have both the full spectrum and higher nanometer ranges of color for all growth stages.

The result is a light source that can enhance the photosynthetic properties of chlorophyll greater than even natural light.

If you are growing cannabis for the first time, full spectrum fixtures are what your cannabis plants need!
