If you're in the market for energy-saving LED lights for your cannabis garden, check out our list of the top 10 marijuana LED grow lights. Whether you're a first-time or experienced grower, our guide on the best LED lights for cannabis compares wattage, yield, durability, spectrum, and other critical factors to help you grow the best buds.
Types of LED Lights
When shopping for LED lights, you'll run into a few different styles to choose from. The following 3 types of LED grow lights each have their own advantages and disadvantages.
The spread style of LEDs offers bulbs spread out over a large area.
- Quantum Board: Quantum boards offer relatively low-wattage LED lights with high energy efficiency.
- Spider LED: Low-wattage lights are spread out over several “arms” coming out of the main spine. These are a bit more expensive than quantum boards but offer tremendous results.
Traditional panels are the most common type of LED lights. This standard set of lights use medium-wattage diodes on a compact board (compared to spread style boards). For large gardens, multiple standard panels are needed.
Chip on Board (COB) LED bulbs are larger than the standard small diodes found in spread style and traditional panels. COB style LEDs provide a more intense light compared to other styles. COB panels usually come with a few large COBs for maximum light penetration.
Auto COBs work similarly to COBs but rely on a single bulb. Auto COBs can be plugged in standard light sockets. Each has a different light spectrum, which is helpful if you have plants with different lighting needs.
LED Lighting Considerations
Before you buy LED lights for your cannabis garden, there are a few considerations you must keep in mind.
How big is your garden? Can the LED lights you are considering cover the entire space? Make sure you accurately measure the size of your garden. Each type of LED light covers a specific range of space. Check the customer reviews to see if the manufacturer’s listed range is accurate.
Of course, higher-quality LED lights will come with a steeper price tag. For first-time users, start off with a lower-priced option to get the ball rolling. For experienced users, a higher-quality light is in order. Pay attention to the brand’s reputation and quality of lights. Check on customer reviews to get a good idea of their durability, efficiency, and ease of use.
When buying lights for your garden, you’re going to need certain light spectrums for different stages of growth. A full-spectrum LED light can meet all of your growing news. Full-spectrum lighting provides the red and blue spectrums you need, as well as infrared and UV lighting. Full-spectrum lighting can run cool and save tons of energy over time compared to other lights.
In general, LED lights provide a higher energy efficiency than fluorescent or HID bulbs. When searching for a grow light, consider its total wattage output. Higher outputs mean more power and energy efficiency.
As mentioned above, plants need different light spectrums during different stages of growth. Additionally, they need certain light cycles during each stage.
- Seedling: 16 hours of light, 8 hours of darkness
- Vegetative: 18 hours of light, 6 hours of darkness
- Flowering: 12 hours of light, 12 hours of darkness
