Growing cannabis under led lights

Energy Saving: One of the main features of these lights is that they consume very less energy. It is found that LED lights save up to 50-70% more than other grow lights. Also, the intensity of the lights doesn’t fade away with time. LED lights are expensive but their durability and energy-saving features make them the first option for growers.

You can say it can be a hybrid of these two LEDs. You can adjust them accordingly and use them as per your need. These types of lights emit a wide spectrum of light that helps you to produce good quality weed.

COB Style

The spread-style type of grow light emits an equal amount of light to a large area. The spread style has panels that have small holes. The small LED lights are fitted in these holes on a large area. The spread-style LED lights are further divided into quantum board and spider-style.

There are many indoor marijuana growers who prefer LED for indoor cultivation. It provides the correct colour spectrum that influences the THC content, terpenes in the marijuana plant. So you tweak the plant growth according to your requirement. In this article, we will learn about the LED lights, their importance, and many more

Spread style

Maintain Moisture and Save Water: Other grow lights emit heat that soaks the water in the plants. Thus, you will save a significant amount of water if you use LED lights. Because LED grow lights can also preserve the moisture of cannabis and produce a higher yield.

If you are willing to step up the quantity of your grow, that is, really take it to the next level, you should be prepared to spend a little bit more cash. A large scale 350-400 watt LED operation that will outdo the average 600 watts HID lighting system is not going to come cheap. However, a larger LED light setup will still be more cost-effective than an HID setup of the same size.

It used to be that lighting was one of the most expensive aspects of growing marijuana. A good set of HID or CFS lights could set you back a couple hundred with all the required equipment. Now, thanks to LED lights , cannabis grow lights are much more affordable, making growing cannabis at home much more attainable.

Another thing to consider is how much money LED cannabis grow lights will save you on your energy bill. HID lights are good at what they do, but the amount of energy they use will cause your energy bills to skyrocket. This not only hurts your pocketbook, but it can also draw unwanted attention in your direction either by a landlord, a nosy neighbor, and/or the police. When people had to keep their marijuana growing activities under wraps, spiking electricity bills often gave them away. While cannabis is legal in more areas now, this does not necessarily mean that you want the whole neighborhood knowing what you are up to.

Finally, LED lights last longer than HID or CFL bulbs, ensuring many years of good use before they need to be replaced. Traditional cannabis grow lights last for only 20 thousand hours. In contrast, LED bulbs last more than twice as long, for up to 50 thousand, or sometimes even 100 thousand hours. That’s five times the life of HID lights!

With LEDs, you don’t have to place your plants as far away as you would with HIDs. Keep lights below 300 watts about 30-70cm away, or just around 12-27 inches. Lights above 300 watts should be kept at 70-80cm away, while gradually decreasing space when flowering. Larger wattage like 450 should be close to 80 cm or 31 inches.

You should also be aware that while LEDs don’t put out as much energy, your plants are still susceptible to light burn. So, like any other lights, make sure that you are keeping your lights a proper distance from your plants and keep plants dry when under direct light.

Those who could not afford a good set of HID lights would resort to CFLs, which, while not as effective during the flowering phase , managed to get the job done most of the time. Often times, these were the only options for growers with smaller operations, or those growing a couple plants for personal use. CFLs have gained some popularity over the years, but they would never be as popular as HID lights, which are trusted by growers all over the world. That is until LED lights entered the picture.

Growing Cannabis Using LED Lights

The main types of cannabis grow lights are HID, or high-intensity discharge, CFL or compact fluorescent lights, and of course, LED or light-emitting diode lights. HID lights were the most commonly used cannabis grow lights when indoor growing first became popular in the 1990s. This was because they produced just the right number of lumens to grow cannabis indoors.

There are many reasons to use LED lights when growing cannabis.

Selecting the Wrong Light Spectrum
In order to grow efficiently, plants need different types of light for each growth stage. With full-spectrum LED lights this is easily achievable, but if you select the wrong setting, the plant will not develop well. You should also take into consideration the conditions in the room where you’re doing the growing. For example, plants benefit most from light in the blue spectrum when they’re in the vegetative stage of growth. That means that if you set the light to emit light in the red spectrum, you will only be hindering the plant’s growth.

Overheating the Plants
You will know the plant is taking too much heat if the leaves that are closest to the light start turning brownish. The first signs look like thin outlines on the outside of the leaves, so if you catch this quickly you will have a chance to avoid further damage. If some of the leaves start curling up, it might also be a sign that the plant is too close to the light. Good ventilation usually also helps with this issue.

Overwatering When Switching from HIDs to LEDs
Regular HID lights produce a lot of heat and generate lots of infrared light. This dries out the plant and the soil and results in the need to water the plant more often. However, LED lights generate no infrared light and don’t emit nearly as much heat, so there is no need for abundant watering.

Using the Wrong Light Schedule
You should be careful not to leave the lights on all the time, or worse, the opposite – forget to turn them on. It might sound trivial but it’s quite easy to mess up the light schedule and even a minor change might have a negative impact the plant’s growth. Cannabis needs about 18-24 hours of light during the vegetative stage and 12 hours of light during the flowering stage.

Forgetting to Adjust the Lights
Many people forget to adjust the height of the lights as the plants grow bigger and end up with burnt leaves. Another important thing is to occasionally rotate the pots in order to prevent the plants from leaning towards the light too much.

Grow lights are a great tool for making the growing process more efficient, but they can also be harmful to the plant if not used correctly. Here are 10 things you should avoid doing when using LED and other types of grow lights.

Not Considering the Other Factors
LED grow lights are a great aid when growing plants indoors but by themselves they cannot do much. In order to produce big and healthy yields there are a lot of factors that need to be considered – room temperature, airflow circulation, soil, nutrients, plant genetics, and many others things. Don’t just focus on a single part of the growing process. Instead, try to get an overall understanding of the whole chain and how everything is interconnected.
