Best LED Grow Lights 2018: GoGrow V3 Master Grower

Another one of the best LED grow lights of 2018 is the GoGrow V3 Master Grower. It measures 24 inches long by 11 inches wide by 3.5 inches deep and weighs 18.5 pounds. It runs on 100AC-240V (50/60Hz), and is able to work in an environment of -4F to +104F (-20C to +40C). However, this light is not waterproof, so check your humidity levels regularly and only use indoors.


There are many advantages to buying a GoGrow V3 Master Grower. There is no reflector hood, ballast or ducting, which all take up valuable space. You won’t need to continuously replace bulbs like you would with an HID lamp, as LED bulbs have an incredibly long lifespan. This light also runs cool, so you won’t need to dissipate any extra heat with fans or air conditioning. This saves you on space as well as electricity bills.



The full spectrum, high PAR light that the Master Grower emits is high quality, with all the wavelengths needed to grow healthy, high yielding marijuana plants indoors. The wavelengths produced range from ultraviolet light at 410nm all the way to infrared light at 730nm. The output of this light is 320W, but of course the input will be less than this due to the energy efficiency of LED technology.


The coverage of the GoGrow V3 Master Grower is 5 square feet when hung about 40 inches from the canopy for the vegetative stage, which decreases to 4 square feet when hung about 8 inches from the canopy during the flowering stage. The continuous working time for this grow light is 18 hours per day for vegetative plants, and 12 hours per day for flowering plants.


The GoGrow V3 comes with a power cord, two carabiners and two rachet rope hangers for easy installation and adjustable hanging height. GoGrow offer free shipping and a 24/7, 365 days a year North American helpline service, as well as a 90-day money back guarantee and a 3-year no hassle warranty. This company really values customer service, which is great to see.


The only real downside to this grow light is that it only has one mode and so the spectrum and brightness cannot be altered to better suit the growth stage of your plants. However, for such a small grow light it has great coverage and penetration, as well as a broad light spectrum, which is what really matters when it comes to grow lights.


Overall, this grow light is considered one of the best LED grow lights of 2018, not so much because of its lack of growth stage modes, but because of its energy efficiency. GoGrow claim that this grow light will save you at least 50% on your electricity bills, which is a lot of money in the long run.
