Are LED Grow Lights Any Good?

Grow lights are essential for all grow rooms - but not just old light will do. Your plants need - and deserve - high-quality light to make sure they grow healthy and strong. Light-emitting diodes, or LED grow lights, have gained more and more popularity with growers in the past few years.

But are LED grow lights any good? We look at a few benefits and drawbacks.

  • Fast Harvest Cycle. Maximise your plants’ growth rate with LED grow lights, as you can provide plants with light up to 24 hours a day. You can have several harvests per season, altering or adjusting when plants can flower.

  • Healthier Yields. Plants tend to burn or dry easily if left unattended under traditional lights, which translates to them needing more water and energy to keep healthy. LED grow lights, however, are easily adjusted so that plants receive just the right heat without harmful wavelength.

  • Energy Efficient. Another perk of using LED grow lights instead of traditional lights is that they consume less energy while providing the same amount of light. 

  • Targeted Wavelength. Unlike traditional lights, LED grow lights provide plants with the right amount of light spectrum. Yellow and green wavelengths in traditional lights tend to be emitted with high intensity, which tends to weaken plants or make them turn yellow.

  • Longer Lifespan. LED grow lights often have a much longer life span, usually around 50,000 hours or more. That’s around five and a half years of 24/7 usage, give or take a few months.

  • Less Power. LED grow lights are less powerful than other lights, such as HID lights. In general, more power generates more intense light - which leads to a more complete nourishment for your plants.

  • Expensive Short-Term Investment. LED grow lights tend to be more expensive than traditional lights, particularly when manufactured to high-quality standards. Compared to traditional lights, the short-term investment of LEDs is higher but so is the long-term saving potential.

  • Risk of Light Bleaching. Plants can get light burns if they’re too close to the growing lights, which turns the leaves from green to yellow and ultimately white. As plants lose their natural colour, they also lose aroma and potency.
