Best Quantum Board Grow Lights

When you talk about growing a marijuana plant, there are a number of factors that growers need to take care of. Among these factors, one of the most important things is the lighting. A grower needs to make sure that the lighting system is  good in order to get maximum possible yields on their marijuana plant (especially when growing it indoors). Over the course of this article, while we shall be addressing lighting at large, our specific aim is to talk about Quantum board grow lights in great detail! 

When you think of providing lighting to your plants and especially when you think of LED grow lights, you are probably thinking of the chunky blocks of lights which come in panels with glasses on front. However, Quantum board grow lights are quite different from what you are envisioning right now. In this article, we shall discuss in detail as to why the marijuana plant needs lighting and how much light does it need. We shall also be discussing the different kinds of lighting – but our focus here will be on the best Quantum Board LED grow lights that you can get in the markets today. We shall be reviewing some of the best options that you can buy off Amazon right now and provide you with detailed information about it. 

We shall be taking a look at the pros and cons of using such a lighting system. In addition to that, we shall also be putting forward a buyer’s guide which will help you understand the lighting system in a better manner and help you make a well-informed choice while you are buying the lights. We shall also be providing answers to some common and frequently asked questions before we conclude! 

Why Do Marijuana Plants Need Light?

Marijuana plants, regardless of where you are growing them – indoors or outdoors, need lighting. Light is very important for plants to grow as it helps them with the process of photosynthesis and helps them produce chlorophyll as well. Photosynthesis is an important process because that’s how plants prepare ‘food’ which gives them energy. Sunlight also helps break down various sugars and compounds in the plant’s body and it is also based on the lighting hours that they ge that the marijuana plant’s levels of CBD and THC are also affected at times.

Photoperiod is also very important for regular plants (non-autoflowering plants). These plants grow based on the sunlight that they get and they need about 22 to 12 hours of lighting based on the phase of growth that they are in. Different phases of the growth cycle not only need different amounts of lighting but also require different types of light. When the plant is in its early and vegetative stage of growth, it needs more of ‘blue light’ which is on the cooler spectrum of lighting. When the plant matures into pre-flowering and flowering stages, it requires red lighting. However, most growers prefer providing a combination of both these kinds of lights for a better result. 

How Much Light do Marijuana Plants Need?

Depending on different phases of their growth cycle, plants require different amounts of light as well. When the plants are in their earlier phase of growth, they need more lighting. The youngest of them all – seedlings require 22 hours of lighting. As they mature into a proper plant and enter the vegetative phase of growth, about 18 to 20 hours of light would be enough. As they grow taller you slowly reduce it to 16 hours. When the plants enter the pre-flowering phase of their growth cycle, they need about 16-14 hours of lighting and in the peak flowering phase, about 12 to 10 hours of lighting would be sufficient. The plant ‘rests’ in the dark hours. 

What Are The Different Lighting Options?

You can choose between multiple types of lighting options. Some people prefer using a combination of High Pressure Sodium grow lights and Metal Halides (for the warm and cool spectrum respectively). Collectively, they are known as High Intensity Discharge lighting systems. Then there’s also fluorescent lighting in the form of T5 and T12 lights (among other forms) which is also quite popular among growers – but it requires an elaborate setup. The most popular and modern option, however, is using full-spectrum LED grow lights to grow marijuana plants. This is also the crux of our article as Quantum Board grow lights are also LED lights. 

Why are LED Lights Considered the Best?

LED lights are considered the best option for marijuana growers because they are cost-effective when you consider the minimal amount of electricity that these lights consume! While they can be a little expensive to buy, they pay off in the long run because they are really long lasting (over 100,000 hours in some cases) and tend to emit much lesser heat in comparison to other types of lighting. LED lights are also lighter in weight and given the unique nature of their design, if due to some electric issue a couple of LEDs stop functioning, it doesn’t affect the other LEDs. They are also easy to dispose as they are non-toxic.

What are Quantum Board Grow Lights?

When you are talking about LED grow lights, you perhaps think of the regular bulky LED panel. Some growers might also think of COB lights. However, this kind of a lighting setup is the next-generation version of these lights. The quantum board is basically a circuit board where LEDs are wired together and usually feature a heat sink (though some cheaper models might just give you a circuit board and you can add the heat sinks separately). These boards, however, cover smaller areas than their actual size – if you buy a quantum LED board which is 6×6 in size, the light it would provide might be for a 4.5×4.5 area so that’s something you need to take care of. However, the electricity it consumes is almost half of what a traditional light would have cost you.

Factors to Keep in Mind While Buying a Quantum Board Grow Light

Here are some basic factors that you need to keep in mind when you are planning on buying a quantum board LED grow light for growing marijuana indoors:

  • Number of LEDs – You need to check the number of LED lights that this quantum board has on it – the more the number of LEDs, the better the intensity of the light would be – and the faster and bigger your marijuana plants will grow.
  • Coverage – Another very important thing that has to be kept in mind is the amount of coverage that this grow light will offer. The larger the coverage the better it is for you. However, if you are a small-scale grower who is growing weed for personal consumption you can look up for basic lights which offer 3×3 and 2×2 coverages as well.
  • Power ConsumptionThese grow lights usually consume 50% less power than traditional HID grow lights which is always a plus point and some of these lights also support easy dimming which can further reduce power consumption. Also, don’t go by the mentioned wattage and check what is the actual power draw from the wall socket (which is always lesser).
  • Heat DissipationHeat dissipation is an important part of quantum board lighting solutions as these grow lights generally tend to heat up quickly because they do not have any built-in fans on them. They need to have a good heat sink in order to dissipate heat and they also need excellent air circulation inside the grow room/grow tent.
  • SpectrumAlways check if you are getting a full-spectrum light or if this is a specific kind of lighting that you are getting. Sometimes you get a full-spectrum quantum board LED grow light while in some cases there are specific models which offer red or blue (warm or cool) spectrums of lighting. The warm red lights are good for the flowering and pre-flowering phases while the blue lighting is great for plants during the phase of vegetative growth.
  • Cost and WarrantyLast but not the least, the cost and warranty period are always important. Some grow lights offer you a long warranty between 3 to 5 years while there are others which offer upto a year of warranty. Also check the price in which you are getting these lights as that is also crucial for any buyer for any product! Most of these grow lights also have a return policy so do take note of that as well.
