2 power cords like this one

and 2 waterproof connectors

Is there anything else i'm missing, aside from hangers ? also what is the difference between the driver that ends in 1750A and 1750B (only difference i can see in the specs is that B's are IP67 rating)

one more thing - what size wire do i wire the boards in series with? 22 gauge if i am not mistaken? (pls correct me if im wrong)

PS: if anyone has this current set up, if you could share your experience/pictures/par readings with these QBs - thx guys

Different color temp.

I would have gotten all 3000k/3500k personally. Looks like you got 2x in 4000k or even 5000k.

My flower set up shown above is all 2700k. My veg is all 4000k. I have a variety in packaging so I can swap them out and interchange them as I see a need.
What drivers are you using?
I am running lrs-350-36 to run sets of 4 in parrelllel. Each one has a potentiometer and multimeter display. The single is powered by a lrs 75 36. That controls the center board so I can dim it as needed (bright spot likely otherwise in the center).

Beautiful work, man. Love seeing these clean setups.
Thanks a lot I appreciate it

I have a question about those LCD meters. Do you run what's coming in from the AC or the DC side. Say I had 2 drivers I want to be read from 1 LCD. Would I just take the + and - from each driver output and wire them into the appropriate LCD wires? I have been looking into ordering one of those.
