Cool, I am getting good sunlight for most of the day though, and will probably only be running the light from 3 or 4 PM to the end of my lighting period. I am going to start with 12/12 and maybe work up from there. I don't want to exceed the DLI. If I see similar problems others have reported here, I also have a full spectrum COB I can add in to widen the spectrum a bit more. I also had a hunch that the spectrum of these 4000k COBs could be a nice fit since it is pretty balanced Blue/Red and has that bump in green.
edit: Proper seedlings will be going in starting Sunday. These are just test dummies they have too many seeds germinated in them. The seedlings I will add in each week will each have just two seeds.
