Thanks Dr happy. Unfortunately on my first two runs I didn't achieve 1 gram per watt. I only got a little over half a gram per watt, which is decent, but not what I was expecting switching to vertical. I did learn a lot from the past runs, which I've utilized on this run, which I hope to get closer to one gram per watt. Yep I'm only running 1200 watts now, but will actually be running 2400 watts very soon. Yes I do have two levels of plants.
