Grow light placement together or apart?

[Painty]

I’m going to be hanging two Viparspectra XS2000’s in a 4x4 tent. Should the lights hang next to each other in the middle of the tent? If so, how far apart should they be? Or should they be placed on opposite sides of the tent? Thanks for the help.

I would hang them centered, with a space between them, so they are equidistant from the walls and each other.

A PAR meter would answer your question much better.
