I will be updating this thread with a test I will be doing for DNA Lighting Solutions. I have 2 - Phillips 860 watts and 2 - MGD 1000w (Multi Gas Discharge) and the 2 MGD 600w are on the way. Today is day 1 of flower. I am running this in an under current style system with Mills Nutrients. I have 2 Connoisseur Genetics - Cheese Dogs, 3 Rare Dankness - Docs's OG, and 1 DNA - Lemon Skunk.
