Tent stays in garage with door cracked about 4". Outdoor temp lows are high 40's, and tent stays about 12° warmer then garage, lows in garage will hit low 50's. Highs in tent are in 77° early in night and drop to 66, 67, by morning. My best upgrade was moving to 240v, from 110. Allowing me to run up to 4, ballasts.Looking awesome, Brother! That PE is gonna be a keeper! You could see by how early she started frosting up. Can't wait to see in another month once she's got some weight on the buds!
You must be getting some nice cool weather to be able to run all three of those lights at those nice, low temps! That setup is gonna rock!
