What to look for when buying LED grow lights

Below we have rounded up what to look for when shopping for LED grow lights, followed by a list of the the best LED grow lights available on the market today. 
The type of light you use has a monumental effect on your cannabis growing efforts. Many factors go into what LED light to use for growing cannabis. We did the research for you and have rounded up the most important ones below.

Light spectrum

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.

Amount of light

The more light your plants receive, the better they grow. So, how do you find an LED grow light that emits the highest quantity of light? For one, LED lights are already designed to directly aim at the plant. Panels that are 3W per bulb produce the highest yield without burning the plant. More panels help spread light over more area. It’s recommended to use an LED grow light with over 2 panels if you plan on having a large growing space.

Wattage per square foot and coverage area

Your grow lights will be running for long hours, so you’ll want to save electricity.You’ll want to check the electrical output of your light, which should optimally stay over 300W. If the wattage is too high, you can run the risk of burning your plants. The recommended amount for growing cannabis is 50-60 watts per square foot. You will also want to know how much area your lights can cover. Most lights we recommended today have a coverage area of 3 ft x 3 ft at the vegetative stage.

Low heat emission

It’s important to find an LED grow light with low heat emission. You don’t want to run the risk of burning or discoloring your plants. You can put lights with low emission close to your plants, allowing them to receive more direct light. Controlling the temperature of your grow room is important for saving electricity and room temperatures contribute heavily to plant growth. If the air is humid, similar to the tropics, your plants grow optimally. Grow lights that emit too much heat turn the air dry, meaning your plants won’t grow.

Quality of materials

LED lights can be an expensive investment and the quality of your light source highly affects the yield. You want an LED light that gives off 3W per bulb, meaning the semiconductor chip needs to be of high quality. You need to look for durability; very durable LED grow lights last for 50,000 hours plus. Look for manufacturers that state longer warranties (2 years plus). They are most likely using the highest quality materials. Most grow lights we suggested today come with a hanging hook and power cord.
Now that you know what to look for when buying LED grow lights, see below for our reviews of the top ten LED grow lights on the market.
