600W or 1000W? 4x4 scrog

So, I'm about to run a 10 light garage grow.
I'm running skunk, lsd and strawberry lemonade, which is semi irrelevant since its a scrog grow.
However im concerned my 600 watters will not cover my 1.2m2 scrogs in such a way of creating nice buds especially toward the outer 2-300mm of the scrog.
I'm running one plant per light per scrog.
Is my worry unjust or should I switch to 1000watts?
Money is a nonfactor, neither is heat or hanging distance.
Or could I go one better again and run 2x600 watt over each 1.2m2 scrog?
Any input would be greatly appreciated, ive been absent from this page for years however am considering covering this grow and then my cloning and pepetual from there on our.
Thanks rollers!

4x4 flower you'll want 1000w. The 600 is good for 3x3 flower.
Better to have the 1-1000W per plant than 2x- 600w that you have to worry about crossover coverage/hot spots.

I run 2x- 1000w in a 4x8. Changing my grow up ask we speak to a 10 week veg/2 plant cycle. So, 1 plant per 4x4 x1000W.

If your in a garage and have the ceiling height, look into 1000w double ended HPS fixtures. Thats what most commercial growers run.

I'd say it mostly depends on the type of lamp. A high-efficacy LED at 600 watts will be good for a 5 x 5 foot grow area.
Also, if the layout has reasonable overlap of the lighting coverage. So many variables.
