18 CXB3090 COBS and a 8x4 space??

Hey folks.. by this time next week courtesy of Timber Light DIY I will be in possession of three 300w six CXB3090 COB kits totaling 900 Watts. Each kit will be complete with heat sinks and Meanwell HLG 320H drivers and potentiometers (dimmers)
I would value your opinions/suggestions concerning how to lay out my arrays in my 8x4 area. I was given the option to operate each array individually OR as a single unit. I think I'm going to go with the single.array option. On their recommendation I'm going with the 3500k variant. Soooo. How should I set up my 18 COBS in my 8x4 area ?? How do I determine the best layout for optimal use it what I've got. Is there a formula or what??
Thanks so much for your help."

Thanks Verticalg but how do I figure out the spacing? I mean how close to the edge of the space should the cobs be? They say 15 inches on center but I'm just not sure on placement. Maybe I'll just put a sheet of plywood on the ground and use that as a template of sorts.
What do you think about running the three arrays as a single unit with one potentiometer versus the three arrays being independent of each other. Also would you go with 3500k on everything or mix it up? See Yuh
