Top 5 Best Quantum Board Led Grow Lights in 2021 (Don’t Miss)

The biggest question lingering on the minds of growers is; are they effective and reliable as other LED grow lights?

As you will find out later in this review and guide, Quantum Board LED Grow Lights, normally shortened as QB LED grow lights are very efficient and effective in performance. These lights have several advantages over COBs such as better efficiency and much easier thermal management.

Grow lights, in particular, are the most important because essentially what they are doing is that they are emulating the natural light and heat that the sun provides to the plants. Plants need light and heat because they use that to create pigments and energy with processes such as photosynthesis. This is what helps them grow stronger and healthier. Furthermore, especially for cannabis plants, grow lights are of another importance — based on the kind of heat and light you provide at different stages you can somewhat alter the chemical composition of the plants getting a stronger or a lighter flavor in the weed that you are going to smoke! Hence, it is essential to know about grow lights and understand their functions.

What is a Quantum Board?

The Quantum board is a large circuit board with several LEDs mounted to it. The LEDs are then linked together in a series to create strings, and these strings are later joined in parallel configurations to make them compatible with normal high-powered constant current drivers.

What To Look For In An LED Grow Light?

Since many of our first-time buyers experience difficulty choosing the best LED grow lights for their plant’s particular needs, our team of experts offer these tips for choosing LED grow lights. Here you`ll find all the vital information for making an informed choice and selecting the right product and model.

Consider What You`Re Going To Grow

The first thing to do when choosing LED grow lights is to consider the crop you`ll be using them on. All products available on the market work for getting the plant to the flowering stage but certain ones are better suited for certain crops. The AdvancedLED diamond series is suitable for almost any crop and specifically good for growing cannabis on a full cycle. The specific models include the Diamond Series XML, the Diamond Series XTE and the Diamond Series EX-VEG. The specific wattage you should choose depends on how many plants you want to grow and the grow space itself.

Choosing The Right Type Of LED Grow Light

Making the best choice means that you have all the information and option available. After talking about how different lights are suitable for growing different crops it`s time to delve deeper into the types of grow lights.

For growing cannabis from a seed and nurturing it through to the flowering stage the best way is to get a full cycle LED light. However, you should keep in mind that in some cases you`ll only have to use it for the vegetative and blooming stages.

Grow lights for cannabis and specifically those that aid the plant during the flowering stage are available in different models, differing in the number of channel lights. A single channel light features on and off options, whereas the 2 channel models feature separate vegetative and bloom modes along with programming options, which can be found in all of the high-end AdvancedLED models. These models can be programmed with different light schedules to best cater to the plant`s need without you having to do it manually. Also, the light spectrum is customizable in order to provide light in the correct spectrum for the given growth phase. This is the latest stage in the development of high-end LED grow lights equipment that is setting the standard for the whole industry.

Another aspect in which lights differ is shape. There are models shaped as panels, bars, saucers and lightbulbs, suitable for every need depending on the grow space and area, which leads us to the next important question.

Taking Into Account The Size Of The Grow Space

In LED lighting bigger wattage doesn`t automatically translate into a bigger area coverage, as it is with regular HID, MH and HPS lights, but it can still serve as a good rough estimate. However, the most accurate metrics are the so called Photosynthetic Photon Flux Density (PPFD) and the Daily Light Integral (DLI) that serve to determine the number of lights to the power of lights ratio, but for simplicity and coherence we`ll use wattage as the metric to determine the light coverage area.

Plants and especially cannabis need most lighting during the flowering stage, so we`ll be using that as an estimate of how much area needs to be covered. A standard LED grow light must use more than 32 watts per square foot of grow space, but for optimum results it should be over 50 watts, up to 80 watts.

Consult with the following bullet points if you need a quick guide for calculating how many watts you need for a given grow area.

• 1 by 1–32 watts
• 2 by 2–128 watts
• 3 by 3–288 watts
• 4 by 4–512 watts
• 6 by 6–1152 watts

LED chip quality

Quality diode manufacturing comes at a price. Each diode must be manufactured according to accurate specifications to emit the correct wavelengths and maintain its integrity over time. “Light Emitting Diodes are made from exotic semiconductor compounds such as Gallium Arsenide (GaAs), Gallium Phosphide (GaP), Gallium Arsenide Phosphide (GaAsP), Silicon Carbide (SiC) or Gallium Indium Nitride (GaInN) all mixed together at different ratios to produce a distinct wavelength of color

Each diode must be manufactured according to accurate specifications to emit the correct wavelengths and maintain its integrity over time.

As you can imagine, there are reputable manufacturers who use sophisticated technological processes to assure the diodes they produce emit the correct light wavelengths and are highly durable electronic components. On the other hand, there are a plethora of cheaply produced LEDs that aim to attract budget-conscious shoppers who may be unaware that differences exist in LED’s quality. Cheap LEDs may or may not emit the wavelengths that our plants need, and their emitted light intensity can also change in wavelength and/or decline within weeks or months after use begins and the diodes heat.

In all types of lights, the quantity of light emitted (measured in lumens or PAR photon irradiance) decreases with use. Traditional incandescent light bulb output diminishes much more rapidly than LEDs. Well-designed LED luminaires can retain 70% of their initial output for 50,000 hours or more, depending on operating conditions and other factors.

Our LED engines use only components from reputable, top-of-the-line manufacturers. We use high performance Cree LEDs because we know that quality in LED technology is definitely worth the price.

Final thoughts

Plants have evolved to grow well under light cycles that the Earth provides them outdoors. Long bright summer days and shorter less bright Fall and Spring Days. This is why it is best to replicate these light cycles when growing indoors. The following light cycles are recommended (by growth phase):

• Seedling/Clone Phase: 16+ hours on, 8- hours off
• Vegetative Phase: 18 hours on, 6 hours off
• Flowering Phase: 12 hours on, 12 hours off

A change in the light cycle will actually help trigger the plant to move on to the next growth phase, specifically from Vegetative to Flowering. It’s also important to keep in mind that some plants react poorly to interruptions in their light cycles. Turning a light on in the middle of a dark phase, perhaps to check on your crops, can be detrimental to overall yield and should be avoided.

By the way, Best Quantum Board LED Grow Lights can be your great choice.
