LED grow lights are LED lights designed in a manner to emit specific colors of light under powerful sufficient intensity to aid in the growth of crops indoors. Cannabis sativa cultivators have really benefited from this invention. They have in significant numbers turned to using LED grow lights to grow their plants indoors. Reason being, it significantly assists in the production of top-shelf cannabis.
You may have heard the term knowledge is power and nothing could be more accurate when it comes to setting up an indoor grow operation. There’s a lot involved, true, but as long as you take a methodical approach to your set up there’s no reason you shouldn’t have great success. With the emergence of counterfeit products, you are likely to be lured into buying fake LED grow lights. Therefore, it is very vital you do some in-depth analysis of the available LED grow lights before buying.
LEDs are super easy to set up. Small ones are literally plug and play. Once you have plugged them into a wall you may just hang them above your plants. They are the way to go for an easy setup that still grows great yield.
They don’t run very hot but for a professional production you still will have to set up exhaust fans and organize airflow and temperature throughout your growing facility.
Make sure to keep enough distance to your plants with LEDs to avoid light burn. Also, be sure to get a light that includes green and white light for full spectrum. Only red or blue light will not be enough for your plants.
LEDs are the way to go for small production up to 1 ounce of cannabis per month, but produce slightly lower yield per watt than HPS and Metal Halide lamps, and are generally less optimal for professional grows.

LED lights are optimal for the following reason:
- They provide a custom spectrum of light
- They give off more direct light than other bulbs, which is best for small growth space
- They’re more efficient for higher yields per wattage
- They give off less heat, saving electricity and allowing you to have the most effective conditions for speedy growth
While plants can grow under most spectrums, to make the process efficient they need specific wavelengths throughout each growth stage. High quality LED lights provide the full spectrum of light, allowing you to select the best one for each growing stage. Plants naturally react and grow based on the spectrum of light they get outdoors. They will grow as long as they receive blue and red lights, though most good LED lights offer the full spectrum. The spectrum you use in different stages will affect the plant’s growing patterns.
Blue lights (400nm – 500nm): Blue lights are often used in the vegetative stage of growth. That’s because this spectrum mimics the sunlight during summertime. Plants use this blue spectrum as a hint to spread its leaves in order to soak up as much sun as possible during the summer. It’s recommended to use blue light during the plant’s vegetative stage so it spreads and grows leafy. However, if you use blue light throughout growing you’ll get plants with short stems but with large healthy leaves.
Red lights (660nm – 730nm): Red or yellow lights are often used in the flowering stage of growth. This spectrum mimics the sunlight during the fall. This is when plants grow tall to prepare for the upcoming winter. Taller plants are in a better position to bud and pollinate via winter winds. Using more red light stimulates your cannabis to grow taller and flower (promoting bud growth).
Since you’re playing the role of the sun, you can choose the optimal spectrum of light for the strain of weed you’re growing. Most LED grow lights come with customized spectrums of light that are optimized for speedy growth. Manufacturers often state the great PAR of their LED grow lights. Photosynthetically active radiation, or PAR, is the wavelengths of light between 400nm and 700nm. These wavelengths are the best for photosynthesis.
Metal Halide (MH) lights typically come in an integrated fixture with an external ballast and reflector hood, and will need proper ventilation due to high heat output.
The bulbs, along with High Pressure Sodium (HPS), the other type of HID grow light, produce the highest yields per watt of electricity out of any grow lights available. For this reason, they are the go-to for professional growers in the later stages of plant development.
Metal Halide produces a bluish spectrum which is ideal for the vegetative stage.
Your plants ability to perform photosynthesis is the key to your commercial success. Make sure to put some thought into your lighting before getting started. Shining just about any light on your plants is not going to do the trick.
Light waves come in a colour spectrum. The sun is a full spectrum light. A low light intensity might lead so long plants because they stretch to receive enough light. When having high intensity your plants may turn our shorter. You can adjust the light intensity by choosing the distance from your plant.
In the vegetative stage your plants will want up to 18 hours of light. In the flower stage they grow best in 12 hours of light and 12 hours of darkness. Your ability to choose the rhythm of lighting lets you create the perfect light timing for your plants.
Make sure you provide a minimum of 6 hours of darkness for your plants. The 12/12 hours flowering cycle will make your plant believe it is late summer which is their time to develop buds. You want to start this after 2 to 4 weeks of growth in the vegetative phase. This is the time where you can switch from fluorescents to HPS grow lights.
For plant growth there is an optimal amount of exposure to lumens that will result in the healthy plants you’re looking for, and that’s really our main concern. You want to make sure that your LED lights give off enough lumens to spark the photosynthesis process to ensure that your plants have a healthy growth cycle and produce crops at the end of that cycle that you can either sell or use for your family.
If you’ve ever sat in a room with a dull bulb there’s a good chance you started to get sleepy after a while; that’s because the bulb wasn’t emitting enough lumens to trick your body into believing that it was still daylight, so your natural inclination is to want to go to sleep. A bright bulb, on the other hand, will likely make you much more alert and focused on the task at hand. Your plants are affected in a similar way, only probably even more so. Without enough light they simply don’t function as they should and the more lumens that your bulbs are emitting the brighter they will be.
LED lights consume much less energy than traditional bulbs which means, for example, that an LED light that consumes between 6W and 10W of energy can actually produce the same amount of light as a 50W halogen or florescent light might do. This is because it can produce the same amount of lumens at a much lower level of energy consumption. If you’re going to have a successful grow operation it’s important to move away from looking at watts and instead look at how many lumens the light you’re using produces.
How many lumens do your plants really need? That’s a very difficult question to answer and it really depends on a lot of different factors. You have to consider how big your room is, what type of plant you’re growing, and what type of yield you’re looking for. There may be no ideal amount, but, generally, if you can produce somewhere between 300 and 800 lumens per square foot your plants should prosper quite nicely.
Afford-ability is very essential before choosing a product or service. You have to make sure, after acquiring the product or service; you will not run out of cash for essential activities. Therefore, as you choose on a LED grow light, ensure it is affordable and does not compromise quality. An indoor grow operation requires a lot of attention to detail. Understanding how everything works isn’t that complicated, but it does require an investment in time. If you take the time to set up your grow operation properly you should have healthy plants with abundant yields that leave you with a satisfied feeling overall.
