I have Y splitters, but they won't fit in my lamps unless I ditch the reflectors, but then I'll be wasting lumen's, so i figure for now I'm good with the current set up, my plant is growing fine I have about 4100 lumen's, all focussed on one plant so I'll add more if I see it necessary, but as fast as it's growing, I'm good with this. However I do have to say thank all of you for your help... And I will definitely add more eventually...
