“LEC” and “CMH” both refer to Ceramic Metal Halide grow lights, which is a type of HID light that is a bit more efficient than a regular Metal Halide light
Note: Some growers may have heard of “Induction” grow lights, which are pretty rare these days but still pop up from time to time. There are two types: “Magnetic Induction” grow lights do okay for growing cannabis but they’re pretty much glorified fluorescent lights. “Plasma Induction” grow lights actually perform pretty poorly at growing cannabis.
Note 2: Incandescent light bulbs (old fashioned light bulbs) are NOT suitable for growing marijuana!

3.) LED Grow Lights
Now that you are familiar with all the most common cannabis grow lights I hope your choice is a little easier. I wish I’d had this information when I first started growing indoors Happy growing.
LED grow lights are very popular among cannabis growers as an alternative to HPS grow lights. They tend to run cooler and also usually come with built-in cooling. They can often be plugged into a wall and simply hung over plants which is definitely easier than setting up an HID grow light. LEDs also have great penetration so they don’t need to be moved frequently like fluorescents.
3 Main Classes of Marijuana Grow Lights
High Pressure Sodium grow lights are often used during the flowering stage because they are very efficient and their yellow light stimulates bud production. HPS grow lights in the flowering stage get better yields per watt of electricity than any other type of grow light available today, which is a big part of why they are so popular.
So, there you have it. These are our five top picks for fluorescent lighting that will show some love to your cannabis plants. Make sure to do your research, though, as there are hundreds of fluorescent lamps available on the market.
Growers who have complex lighting set-ups using multiple lighting types often use fluorescent bulbs during the sprouting stage. Young plants respond well to these bulbs, but older plants sometimes require something more powerful. Sadly, you may get lower yields than if you used LEDs at a later stage.
You can hang the lights overhead, vertically, or horizontally closer to the plants according to your preference. There is a 10ft grounded power cord to help you reach, and the powder-coated steel housing protects the T5 tubes.
As you can see, choosing the best fluorescent light is a bit of a trade-off. That’s why professional growers will change between different types of lights during different stages of growth. If you’re not that serious, though, and are just planning on growing one or two plants, then fluorescent bulbs will work just fine.
5. Hydrofarm FLCDG125D Fluorowing Compact Fluorescent System
Although this model doesn’t offer vertical positioning like the EnviroGro FLT24, it does offer two modes of light. Switching off some of the tubes allows for dimmer light that works better for times when you need it a little darker.
There is much debate about what lighting type is the best for marijuana. Fluorescent lighting is a commonly used form of lighting, but you still need to learn which bulbs work best. In this guide, we cover the pros and cons of fluorescent lamps and explain where you can pick up the best fluorescent light for your grow space.
If you’re looking for T5 bulbs, then this option is fantastic. The EnviroGro FLT24 T5 lights are a little more expensive, but we think they’re worth it.
Other Types of Lights
For a relatively cheap price, the Hydrofarm FLC125W light provides excellent light quality. It can be placed both horizontally and vertically. The bulb provides 125-watt full-spectrum light in a warm tone.
T5s are the preferred fluorescent bulb of choice for more experienced growers. However, CFLs definitely work, too. Bear in mind that you’ll have to put up with a smaller yield with both types of fluorescent lighting.
