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.

You can find HID reflector hoods, as well as MH and HPS bulbs at any local grow shop.

New LED grow lights come out all the time, but knockoffs abound. There are a lot of cheap LEDs that don’t produce the right spectrum of light for plants.

MH (Metal halide)

Make sure you have enough outlets and power available in your breaker board for your grow space to comfortably accommodate all equipment. Figure out all pieces of equipment, such as lights, fans, possibly an AC or dehumidifier, and calculate how much power they’ll require. You’ll be running this equipment every day for months, so if you don’t have enough power it can be dangerous. Never overload an electrical outlet.

Actual Power Consumption: 180W

Average Yields: 5.5-8+ ounces – keep in mind that the strain (genetics) and any plant training you do makes a huge difference in your final yields. Some growers are getting even better yields with this light, it seems to be performing very well in tests.

AutoCOBs

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”.

Grow Space: 2.5×2.5’ coverage at 24” (suitable for vegetative stage) and 2×2’ coverage at 18” (suitable for flowering stage)

Quantum Board

The most important thing to remember about choosing LED grow lights….

Many smaller LEDs are spread out over a large area. Examples of this style include Quantum Boards, Rack and “Spider style” LED grow lights.
