Even if you’d like to grow more than a few plants, you don’t have to go for the more expensive HID lights. Simply add to your setup with either a few larger LED bulbs or several of the smaller ones. If you opt to go for the latter option, make sure that your plants and your lights are spaced out correctly, as you want to make sure that each plant gets adequate amounts of light. Using too few lights can cause stretching, whereas using too many lights leaves you at the risk of light burn, as well as energy overconsumption.
Not only are LED lights more energy-efficient , but you’ll also save on water usage as well. As you are now aware, HID lights use a lot of energy, which in turn produces more heat. This dramatically increases the temperature of the grow room, causing your plants to consume more water. Cannabis is already quite the water hog when compared to other plants and growing even just a small amount of plants uses a lot of water. Any way to reduce water consumption is great for the environment, not to mention great for your utility bill.
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.
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.

There are many reasons to use LED lights when growing cannabis.
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.
If there is one drawback of using LED grow lights, it is that your plants’ grow time will be slower than if you were using HID lights. Again, this is because HIDs emit more energy than LEDs, leading to faster flowering.
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.
The benefits of using LED cannabis grow lights are many. The next big question is how to grow marijuana using only LED lights. A good rule of thumb is one light per every 1.5 square feet. This generally will yield you up to 6 ounces per plant, which ends up covering what you spend on the light and will definitely end up saving you money in the long run. If you are growing only 1-2 plants, our single 75 watts LED light supplies plenty of light for your plants.
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.
Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process. If you're using regular incandescent lights, you're not very likely to grow strong and healthy plants. Therefore, for best results it is recommended that you use full spectrum LED grow lights. They are specifically designed for the purpose and have the feature to deliver light in the exact spectrum the plant needs.
Overheating or insufficient lighting can result from having too many or not enough lights, but it can also result from placing the lights too close or too far from the plants. There is no universal rule for setting the distance but it's recommended that LEDs are placed 12 to 18 inches away from the plants.
For people who use cannabis derived products on a regular basis, it is very tempting to try growing the plant at home. The benefits are quite obvious: the cost is drastically lower and there aren't any hassles related to the actual purchase of medical marijuana.
Overwatering When Switching from HIDs to LEDs
In this article, we'll provide you with the 10 most common things you should pay attention to when using LED grow lights so you can grow healthy looking plants and avoid any unnecessary hassle. This information is extremely relevant to beginners.
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.
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.
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.
LED grow lights are your friend and an important investment, so you need to take proper care of them. They bring numerous benefits to the growing process and a little maintenance and preparation can save you a lot of trouble. It is recommended that you set up a power stabilizer and connect it to the lights in order to equalize the incoming voltage, thus protecting the chip inside the LEDs.
