GIVEAWAY During the Live Premiere! Sunday Feb 19th, 3pm Eastern – Noon Pacific
This is an Update! I first tested the Mars Hydro FC-6500 in January 2021. There have been several updates since then, so I got the latest model and ran it through several Tests in 4x4 and 5x5 areas for growers with and without supplemental carbon dioxide.

19:38 My Review

I conduct independent and impartial grow light testing. I present the data that I gather during my tests. The opinions and recommendations that I offer are based on my experience with indoor horticulture and horticultural lighting.
The manufacturer provided me with the light fixture to test and review. I always retain the right to give honest opinions about the products that I review. I do not offer manufacturers exclusivity or give them any editorial control over my reviews. The opinions and analysis are my own.
