“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
CFL grow lights are the twisty-looking bulbs you can find anywhere you normally buy light bulbs. They produce a great spectrum for growing cannabis and can be used in tiny spaces where no other grow light would fit such as the inside of a cabinet.
Simply hang an LED light over your plants and start growing!

(LEC stands for “Light Emitting Ceramic” and is a type of Metal Halide bulb that is built with ceramic like an HPS – basically it’s sort of like a blend between MH and HPS bulbs)
Pros of Fluorescents
If you get very high-wattage LEDs, you may need to vent out heat to keep the grow space cool
More Light = Bigger Yields!
(up to a point, it is possible to give your plant too much 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.
The light from an HPS appears yellow, and is great for flowering plants because the light spectrum stimulates bud production
Fluorescent lighting works through a chemical reaction inside the bulb. Mercury vapor reacts with various gases to create an invisible UV light, which then illuminates phosphor powder that creates light. For this process to take place, you also need electricity; the current is what triggers the reaction. As a result, you often end up needing a socket for each bulb.
Other Types of Lights
