Cannabis Grow Lights

Cannabis Grow Lights

For the many growers who are unable to cultivate cannabis outside in the free abundant sunshine, grow lights are necessary to successfully grow cannabis indoors. Grow lights take the place of the sun, and power the growth of your plants and their buds. Light is like “food” for your plants, so without a lot of bright light, even a healthy cannabis plant won’t produce much bud at all.

More Light = Bigger Yields!
(up to a point, it is possible to give your plant too much light!)

Marijuana plants growing under the sun – in order to replace the sun indoors, growers need to get cannabis grow lights

There are lots of options for grow lights that work well for growing cannabis indoors but in the end they boil down to 3 major types:

1.) Fluorescent Grow Lights

Compact Fluorescent Lights (CFLs)
T5 grow lights (and other fluorescent tubes)
2.) High Intensity Discharge (HID) Grow Lights

Metal Halide (MH)
High Pressure Sodium (HPS)
Ceramic Metal Halide (CMH, LEC, Light Emitting Ceramic)
3.) LED Grow Lights

(LEDs come in a huge variety of sizes and form factors. There aren’t really any “standard” types yet, though some lamps get better results than others.)
Incandescent light bulbs are not suitable for growing cannabis!

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.

Some types of induction lights are well suited to stadium lighting but honestly they just aren’t that great for growing cannabis and they come with huge price tags.
