Couldnt go to a better grower in a better state! Lol

Im an old guy, so i take my naps and read in the lung room. In between I visit the girls for their daily checkup and admiration. It raises my co2 from 450 ppm ambient to 6-650 ppm and it will usually hold there for several hours. Not a perfect solution when I’m running nearly 1000 ppfd but it’s free!
