DeRP Farms - Kingman, AZ

DeRP Farms is a medical marijuana cultivation operation based out of Kingman, Arizona. Using their main indoor flower grow room, DeRP Farms tested four different lighting products over four separate 6' x 20' tables for a complete 45-day flower cycle. This side-by-side comparison included Growlite's VARIUS® LED Series Light Bars, two other competing LED systems, as well as their current source of lighting, Growlite's OG 600W HPS lighting system.

6% HIGHER THC CONTENT ON AVERAGE*



All tests were performed on their Wedding Cake strain. All plants used in the testing were previously run through the veg cycle using the same parameters, lighting, and feedings. As the 45-day flower cycle concluded, a sample of each table was sent to a third-party laboratory for THC and Cannabinoid content analysis.

The VARIUS by Growlite led in all categories.

"These things are awesome. The magnetic mount allows for custom lighting set up. With both flower and veg spectrum bars you can mix them or just run one spectrum and watch your plants thrive. The results speak for themselves and we are stoked with how these LED bars perform. For the best in Horticulture lighting, Grow right with @growlite"
