8 Best UFO LED Grow Lights For Growing Weed On 2021

One of the most crucial factors that keep weed growers up at night is the selection of a good grow light. If you intend on having an indoor cannabis garden, you must have already done plenty of research on the different lighting options available in the market. You may as well have asked around to hear the opinions of different people. However, how can you tell that the advice you received is the best option for you?


Light is essential for the process of photosynthesis to occur in a cannabis plant. The more light you provide a cannabis plant, the more the yield you should expect in return. It is vital that you monitor all the other environmental factors such as humidity, temperature, and the levels of Carbon dioxide in the air. Cannabis is highly receptive to the amount of light that you provide as it shows by the size and quality of the flowers.

Due to the advancement in technology, LED grow lights are one of the favorites to many farmers since they promise to deliver greater energy efficiency with lower heat signatures. They offer wavelengths that can be fine-tuned to the stage of growth of the plant and they consume 60 percent less energy than traditional light bulbs. With stories about crackdowns on illegal farms due to their substantial energy bills going around, you need to acquire a lighting solution that counters that problem.

Continuing research in the LED grow lights has led to the pop up of many LED grow light systems in the market designed for use by an indoor cannabis grower. Technology advancement has led to a new type of LED light seeping into the market called the UFO LED GROW LIGHT. The light outperforms the traditional HPS grow lights in almost every manner. It uses a smaller amount of electricity and produces heat that is a fraction of what HPS lights produce decreasing the cost of power consumption and the dangers of plants burning up in your grow room. LEDs are also harder to detect with thermal imaging techniques and are quieter than most HPS lights that emit a hum. UFO LED lights have a high lumen value and can produce a full spectrum of light to help with the photosynthesis of the plant. Here are some of the top UFO LED grow lights that are can provide your marijuana plants with the needed light to ensure healthy growth.

Reasons to Using a UFO LED Grow Lights in Your Marijuana Garden


UFO LED grow lights are with high quality vents and fans that help to minimize the amount of noise it produces.

Low Energy Consumption

Enough experiments have been produced to show that UFO LED grow-lights consume less energy when compared to high-pressure sodium lights while still providing the plants with the required lumens to grow.

Long Lifespan

UFO LED grow lights can last even five times longer than any other grow, helping you minimize the cost of regular replacements and benefit by having bigger, bushier and stronger marijuana plants.

Cost Effective

Even though some LEDs are slightly more expensive than high-intensity discharge lights, the initial cost is an investment worth making since the grow light would help you minimize on energy consumption by 60 percent and there is a reduced chance of losing the plant due to a light burns.

Great Power

A UFO LED grow light can last for long hours without heating up. It helps to deliver the much-needed light by the plants keeping them strong and healthy. Regardless of the garden size, the UFO LED grow light can adjust its brightness according to the level of plant growth.

UV function Capability

Ultraviolet rays play a vital role in the flowering process of plants and also aiding in getting rid of bacteria. The UFO LED grow light has the capability of emitting UV rays that act as the substitute of the sun helping you achieve full plant output.


The materials that make up a UFO LED grow light are of high quality and lightweight making it easy to carry it from one region to another.

Light Spectrum

Photosynthesis takes place when plants appear before specific spectrums of light. The red light range is especially useful in the flowering stage of the plants while the blue spectrum helps to promote plant growth. UFO LED grow lights can produce the two led ranges and help the plants increase in yield.

Low Heat Production

A UFO LED grow light produces a small amount of heat allowing you to place the round LED lamp close to the plant exposing your cannabis plant to intense lighting. Cannabis has been seen to grow rather well when exposed to intense light. Low heat production also means that you may not need to use an air conditioner helping you to save on costs. However, it may still be a good idea to run the provide ventilation to your plants by running a few fans to dissipate the heat that accumulates with time.

How Light Helps the Growth of Cannabis

Photosynthesis in cannabis is brought about by light. As a cannabis grower, your main goal is to attain a high quality yield of buds. However, this comes by due to the amount of light you give the plant. The size and the quality of a cannabis flower are affected by the number of lumens you provide to the plant. To attain the best plant yield, you need to have a minimum of 30,000 lumens for every 10 square feet of your grow room while still maintaining a proper balance of the environment. When the cannabis plant receives plenty of light, it focuses on the production of calyces rather than flowers. When it does not receive enough light, more leaves grow leading to a bad harvest.

The time duration through which the plants receive light is also of importance. During the growing stage of the cannabis plant, you should expose your cannabis to light for 18 hours and keep it in darkness for 6 hours. During the flowering phase, you may switch up the hours to 12 hours of light exposure and 12 hours of darkness. It works exceptionally well for indoor growth since you have total control over the light.

Plant Positioning and lighting

The positioning of plants and light has a significant influence over the overall yield. Placing cannabis plants too close together prevents them from having a good exposure from the grow-light hence affecting photosynthesis. What you want is a uniform amount of light to fall on every plant in the grow room allowing the buds to get the same amount of light regardless of their difference in size. You need to ensure that your plants are well spaced to allow even the smallest plant to get enough light.  The spacing also helps in providing enough room for aeration maintaining the level of humidity.

Even though it may sound cliché, you need to ensure that you place the smaller plants closer to the light source than the larger plants so that they can each receive an equal share of light. A majority of new cannabis growers always overlook this fact and end up with a lower marijuana yield. If all of your plants are of the same size, you should then consider moving them around occasionally or moving the source of light to ensure that all the plants receive the same amount of light. You should also try to prevent light loss as much as possible by making use of a reflector. You need to align the grow-light horizontally to attain the maximum results. Vertical alignment leads to a loss in more light.
