LEDs get better yields for the same amount of electricity than CFLs. This is because LEDs are more electrically efficient (produce more light for the same amount of electricity)
How Far to Keep from Plants: 32″ is the recommended starting distance from the plants.
LEDs are plug-and-play which means you can plug them directly into a wall without a ballast
These plants seem apparently healthy, but the top leaves keep getting lighter and lighter because the LED grow light was too close. If you don’t realize it’s light burn, the symptoms are inexplicable!

Instead of having dozens of small diodes, COB style LED grow lights typically only have a handful of huge COBs, each with strong lenses to direct the light down into the plant. These are rapidly gaining in popularity and are known for having deep penetration into the plant canopy.
How to Use LED Grow Lights for Growing Cannabis
Grow Space: 2.5×2.5’ coverage at 32” (suitable for vegetative stage) and 2×2’ coverage at 24” (suitable for flowering stage)
I’ve seen many growers choose to mix LEDs with their HPS bulbs. In fact, combining MH/HPS with a quality LED panel may be a great way to improve the quality of your harvested buds. There are lots of growers who claim that LEDs increase potency and density, as well as bring out the natural smell/taste of your strain. On the flip side, some growers believe that HPS tends to produce “prettier” buds.
You are willing to do some research to determine the best LED grow light for your space (this article will help guide you)
At THC, we are proud to stock and supply LED grow lights for indoor plants from leading hydro brands like Streetlight, Secret Jardin, Sanlight and Dutch Lighting Innovations. Our most popular ranges are the Gavita Pro 1700e dimmable LED grow light and the impressive Lumatek Attis full spectrum solution.
Providing a broad spectrum of light which is suitable for both the vegetative and flowering stage, hydroponic LED lighting systems produce a lot less heat and are extremely low maintenance. Partner with our reflectors and transform your grow tent into the perfect indoor gardening environment!
With a lifespan of at least 50,000 hours, each one of our LED grow light bulbs can last for up to 10 years – and do not need replacing after every grow-cycle. Although they’re more expensive than CFL grow lights, they’re cheaper to run in the long term and a great alternative to traditional 1000 watt HID grow lights.
LED grow lights are increasingly popular with indoor growers because they speed up the vegetative stage, dramatically increase crop yield and improve its final quality.

Traditionally many cannabis growers fight grow room temperatures, their grow rooms usually running 3 or 4ºC above the optimum point. With LED grow rooms run naturally at a cooler optimum temperature.
Calcium and Magnesium deficiency
A 600W HPS bulb wastes around 450W (75%) of the electrical energy producing heat. A good quality LED light with a 400W power draw would produce around 200W of heat despite having the same productivity as a 600W HPS. So the best LED’s only produce about half the heat of an HPS.
Growroom heat levels are totally different with LED
Growing cannabis with LED is becoming a mainstream alternative to HPS. Although the initial purchase cost of an LED is still higher than an HPS, the ongoing running costs are lower. LED produces less heat than HPS and this affects many aspects of plant maintenance and grow room design.
