Why should you buy LED lights to grow cannabis?

It is a different kind of fulfillment when you harvest the cannabis you have efficiently grown with superior quality and yield. Not to mention the added bonus of a possible expanding market and the sale you can make out of it. Therefore, before you can even begin your career as a cannabis grower, you have to consider the best light for growing your weed. So you might be wondering what makes LED lights relatively on top of the other cannabis grow lights in the market. What advantages can you get if you invest in LED grow lights? Look no further, the answers are here.

Energy efficiency

LED lights are very economical since they produce the same wattage as common bulbs do but with your energy bill a lot lower. Considering they have to be turned on for 10-12 hours a day, the diodes in LED are not only electrically efficient but they do not require constant replacement every few grows to maintain their brightness with their long lifespan

Adjustable Color Spectrum

To ensure maximum growth of your cannabis, you need to have a powerful light with different wavelengths. Red and blue spectrums as well as infrared and ultraviolet are necessary depending on the stage of the growth cycle. Unlike other grow lights which have a fixed color spectrum, you can configure your LED diode to emit a specific color spectrum. PAR which stands for photosynthetically active radiation ranging from 400nm to 700nm holds the best wavelengths for photosynthesis.

Built-In Cooling

Most LED lights do not need additional cooling system since they come with small built-in fans and heat sinks which vent up the air away from the weed. Therefore, it reduces the risk of fire in your place.

Plug-and-Play

While other grow lights require an electrical ballast to regulate current flow and provide sufficient voltage to start the lamps, LED lights are simply plugged in directly into an electrical socket. It saves time for set-up and it doesn’t require an extensive manual reading especially for beginners.

Things to look for when buying a LED grow light

LED grow lights have colossal effects in growing your cannabis. Although grow lights seem to have similar features in the market, they still have their own subtle distinction. Here’s what you want to look for when buying your LED grow light.

Full light Spectrum

The growth speed and the overall robust health of your cannabis are largely dependent on whether or not your grow lights provide the appropriate lights. Most grow lights offer full spectrum with UV (490-395 nm) which is good for seeding and sterilization and infrared (730-735) which aid in flowering and producing viable seeds.

Maximum Heat dissipation

Low hear dispersion is vital in keeping your indoor cannabis alive otherwise it could cause burning your plants in the ground. Check the quality of the cooling systems including the fans and reflectors.

Quality of Materials

LED is actually a pretty neat investment but it can be pretty expensive if you don’t check on the quality of the components. LED lights that give off 3W per bulb has a higher quality of semiconductor chip. You want a durable light with quality hanging hooks, shell casing, and power cord. Grow lights with longer warranty are guaranteed to have higher quality.

Lifespan

The key to a successful cannabis growth is consistency. Some grow lights may last longer and may produce more light than the others. You can save more money if you look for grow lights that offer about 50,000 hours in lifespan.

Electrical Output per Coverage

While most LED grow lights are electrically economical, some may help you save more than the others. It should stay over 300 w with about 50-60 watts per square meter. Look for the coverage area. For the vegetative stage of cannabis, the recommended covered is 3 ft X 3 ft.

Conclusion

While all the LED growing lights are competitive in their own ways, whether by its singular feature or quality upgrade, the Dimgogo 1500W LED Grow Light shows more coverage and wattage, longer lifespan, higher quality of materials and maximum heat dissipation that can support your growing cannabis from vegetative stage to flowering stage.
