- Advanced has really outdone themselves after upgrading their already popular Platinum LED P Series with the diamond series. You can still go for the pLatinum series and that will be completely alright, but why go for that when you have much superior light in the Diamond series. Advanced has really gone and surpassed themselves here.

LED Grow Lights Q&A
Welcome to the section of our FAQ about LED grow lights. This is going to be very helpful for you if you are new to growing weed or if you just want to clear some basics.
What is an LED Grow Light?
- LED: stands for “Light Emitting Diode”.
- Grow: this helps the plants in order to grow in the best possible way when they have been planted indoors.
- Light: this will provide the energy that the plants would receive from sunlight if they were planted outdoors.
The LED grow light includes different wavelength of different lights including visible and invisible which includes IR and UV rays which can directly increase the growth of your weed and ultimately it will result in more yield of any plant that has been grown under these lights.
How do LED Grow Lights Work?
You must be wondering that how can these small lights help your plants grow better even without the sunlight? Plants are known to have a tendency for absorbing more blue light than other lights such as green or white, this makes the UV rays the best ones in order to induce vigorous growth in the plants. The infrared rays are known to be the best catalysts for blooming and germination boost. The wavelengths in the grow lights are adjustable according to the requirements of your marijuana plants in the grow room. When you have your marijuana plants in their vegetative phase, using the UV rays will help increase the cell division as the marijuana plants absorb the rays. Because of the increase in the cell division, the marijuana plants will grow much faster and it will result in more yield. If your marijuana plants are in their flowering phase and you want to treat them, some of the most effective LED lights are the ones which provide infrared rays, or IR. the infrared rays or IR are readily absorbed by the apex and the buds of the marijuana plants and this process causes them to bloom very heavily and quickly. It is recommended that you go for the LED grow light which has a wide range of wavelength options available for you to have the ability to make the most of it in all the grow stages of your marijuana plants. By this feature, you will be able to adjust the effects of the grow light according to your needs. The type of light emitted, Lumen per area, amount of light, the height between the light and the plants, types of plants being grown and wavelength can all affect the growth of the plant that is being treated.
What are the Benefits of Using LED Grow Lights?
Before there were LEd lights, there were other similar methods that were used in order to grow indoor plants. The methods included fluorescent bulbs and high-pressure sodium lamps. Those kind of methods were not favorable at all for the small grow room owners who wanted to have a compact, small structure. Those lights needed a lot of room in order to set up all the equipment and since they produced huge amounts of heat, they needed a proper ventilation system in order to avoid building up of the heat in the grow room and burning the plants. All of these complications made sure that this process was out of reach for the small grow room owners.
The best thing about the LED lights is that they do not take up a lot of space, they do not contribute to extra heat, they do not need their bulbs replaced, they use half the electricity to run and they do not have ballasts to manage.
- Compact and easy to install:
The LED lights come in an extremely compact structure that is very easy to handle. You do not require any specific knowledge in order to install LED lights to your system. All you need is a proper place in order to hang the LED lights above the plants far enough to appease the distance required between the plants and the LED light.
- No need for a separate ventilation system:
The reason that LED lights do not need a separate ventilation system is because they do not emit a lot of heat to begin with. These LED lights are able to work without any help from any sort of a huge ventilation system helping them keeping cool.
- Can be installed right next to each other:
As we mentioned earlier, the LED lights have a very compact design and in addition to that, most of the LED lights allow you to install them right next to each other which in return provide you with more coverage.
- Control and variety:
It is very easy to control the wavelengths on the LED lights and in addition to that, you can also choose between the modes for blooming or the vegetative phase of the plant.
All of the factors mentioned above makes the LED lights much more favorable and give us great results with a lot less cost and hassle.
How Many Watts Do You Need?
When it comes to the LED lights, you do not actually need to worry about the wattage. First of all, you need to understand that wattage is, it is not a measure of intensity or brightness. It is just the measurement of how much power is being consumed at the wall. In some cases such as when you compare two different bulbs with different wattage but have the exact same technology, then the one with the higher wattage will be the brighter bulb.
However, in the case of LED lights, they are considered to be much more efficient than the HID lights, so if an LED light is drawing the same power as an HID bulb, then the LED light will generally be much brighter. What complicates things much further is that there are many different LED technologies competing with each other and there are secondary optics which can be used in order to intensify the brightness even more.
How To Know If Your Plants Are Going To Get Enough Light?
First of all, it depends on the type of strain that you are growing. Different types of strains have different type of light requirements. This is why we highly recommend that you first pick a strain to grow and then start looking at the LED grow lights. As you decide on which strain you want to grow, you will know how much light it needs, all you have to do now is just compare the amount of light needed for your chosen strain with the coverage charts and PAR values which are provided by all the manufacturers of LED grow lights.
A good and reputable manufacturer will always give you enough information about their LED grow lights as to how much grow area it can cover and at what heights it needs to be put for maximum productivity. They will also let you know about the PAR values across the whole footprint. Obviously, you will be needing an LED grow light which will be able to supply as much PAR as your chose strain needs to grow and if you want maximum yields, the more PAR you provide the better your plants will grow.
What Are PAR Values?
The term PAR (Photosynthetically Active Radiation) refers to the wavelengths of light which can actually be used by the plants to photosynthesize. The more of these wavelengths of light that your marijuana plants receive the better. In general, the PAR values are measured in two ways, those are, PPF and PPFD.
PPF or Photosynthetic Photon Flux calculates the amount of usable lights that are being emitted by the grow light. The Photosynthetic Photon Flux is measured in micromoles per second (μmol/s).
The term PPFD stands for Photosynthetic Flux Density. The Photosynthetic Flux Density is an even more important measure because it not only specifies the amount of PAR that is emitted by the LED grow light but it also tells how much of that light is actually falling on your cannabis plant. The Photosynthetic Flux Density is measured in micromoles per square meter per second (μmol/m²/s).
There are some manufacturers that will only provide you with the PPF values and some will only provide you with measures that only indicate from right in the center of the light’s footprint. Both of these tactics allow sub-standard manufacturers in order to make inflated claims about their LED grow lights by only stating the PAR values of the grow light very selectively. So, you need to make sure that you are getting what you need, in order to do that, you should always check the diagrams of the PAR values across the whole footprints and even at different heights as well.
Conclusion
We do hope that you enjoyed this massive guide for buyers for the best LED grow lights in 2020 for your marijuana plants. We wish you the best of luck in growing marijuana independently and hoped that we could help with this informative article. Happy growing!

[…] LED grow lights work on Light Emitting Diodes (LEDs). Here, there are a number of LED chips that are pasted on to a board and once you pass current through them, all these LEDs light up and provide light and heat to your weed. The semiconductor chips on which LEDs operate are known as LED dies, which convert electric current into photons. This process is known as ‘electroluminescence’. Most LED lamps feature LED lights mounted on to a heat sink, which also helps in the easy dissipation of heat. There are directional lenses which allow the LED light to be focused well on the plants.
