I run 2 at 600 watt but veg under a single 600 MH, get at best .75 gram per watt, but 600 watts vs 315 per watt, so you are saying that with 2 - 315w cdl's i should be able to produce double what my 600 HPS does, wow, I know I dont grow as well as some but that’s amazing to me, are you doing Hydro?
