It’s also common to see LED grow lights that only have one COB per lamp. These make it easy to spread out your light over a grow area, one lamp at a time. Sometimes known as “AutoCOBs”.
Introduction: Are LEDs a Good Choice for Growing Cannabis?
HLG first coined the term “Quantum Board” for an LED grow light with the diodes spread out over a large area (on a board). The board style LED grow lights have become very popular almost as soon as they appeared on the scene. Growers are reporting results that may beat even other LED grow lights when it comes to the amount of yield for the electricity used. I was impressed when I tried one myself. It’s probably too early to call it the winner just yet, but it’s undeniable these are some of the best LED grow lights available today!

Modern LED grow lights can produce impressive results. These cannabis plants were grown completely under LED grow lights from seed to harvest!
If you are on a strict budget, Mars will probably be the best option for you. Likewise, if you need UV light, the two SP series lights are the only ones that provide that.
You may have noticed that most LED lights have two different wattage figures. One of these is the potential wattage and the other the actual wattage. The potential wattage is the wattage the light could run at if the LED chips were running at full power. For example, a light with two hundred 3w LEDs has a potential wattage of 600.
The Platinum LED Advanced Platinum Series has six lights, from the P150 to the P1200. The smallest runs on 86 watts and is equivalent to a 150 watt HID light and the largest runs on 690 watts and is compares to 1200 watts of HID light (the one pictured above is the P1200; this link will take you to the Amazon page that shows all 6 lights in the Advanced Platinum series).
Buying LED Grow Lights: Factors To Consider
Their incredible efficiency and their improved yields make LED light the horticultural lighting of the future. And for the countless growers who have made the switch already, they are the grow lighting choice of the present, too.
At first glance, it seems like BestVA is offering a monstrous 3000 watt LED light for an incredibly low price. Unfortunately, this is not really a 3000 watt LED grow light. Not even close.
I make this assumption, because I’ve been there myself. And I’ve helped countless others in the same situation.
Their lights are just as well constructed and they give you the same 3 year warranty to back that up. Performance-wise, they are also on par with HLG and actually have a slightly larger stated coverage area, though they are both about the same for practical purposes. Most importantly, they give you the same even light distribution.
Fixtures come in all shapes and sizes and can usually accommodate 4-12 long fluorescent bulbs; a standard size is 8 bulbs. Fixtures usually have a reflective material to bounce light in one direction, down on your plants.
Another consideration with cost is that some lights run hotter than others—HIDs, for example—so they may require additional fans or an AC unit to cool down a grow space. Extra equipment means more electricity, also driving up your utility bill.
Both types of HIDs are usually inexpensive to buy but will eat up electricity. HIDs throw off a lot of light and heat, which the plants need to bulk up and get potent. But, they run hot, contain heavy metals, and ballasts can fail.
How big a light you need will depend on the number of plants you plan on growing, but also on the size of your space. If you’re growing in a closet or a small grow tent, you’ll only be able to fit one small light in there. If you have a wide open basement, you could invest in a bigger light as opposed to two smaller ones.
CFL lights for growing weed
CFLs (compact fluorescent lamps) are fluorescent lights similar to what you’d find in a school or office building, but smaller. For growing weed, they are usually called “T5s”—the “T” stands for “tubular” and the “5” refers to its diameter, “⅝”.
One of the crucial elements a cannabis plant needs is light. During photosynthesis, a plant converts light energy into chemical energy, allowing it to grow strong and healthy, and with cannabis in particular, light also fuels bud production.
HID (high-intensity discharge) is an umbrella term under which MH and HPS bulbs fall, which we’ll discuss more below. These types of lamps have a hood that reflects light and bulbs that are enclosed capsules containing a gas, as opposed to bulbs you’d find in your house, which have a filament that heats up.
Other considerations when choosing a cannabis grow light
LEDs (light emitting diodes) are relatively new to the cannabis growing world, compared to HPSs, MHs, and CFLs, but they are quickly proving to be the way of the future. LEDs may be more expensive to buy initially, but they are far more efficient and kinder to the environment and your electricity bill. Some cities even give tax breaks to commercial growers who install or switch to LEDs because they’re better for the environment.
HIDs have been the standard in indoor weed growing for decades, but LEDs are quickly catching up to them.
