CMH lamp spacing

Just added a 500w cmh to the room, Currently have 3 315w cmh in a row 3ft apart. Im thinking about putting the 500 in the middle. My question is how far apart do cmh lamps have to be from each other without causing issues? could i space them at 2’?

have not yet had a 500, congrats they sound nice, have had 630’s and 315’s, have had a 630 and two 315’s in the same 5 x 5 flower tent, they were closer to each other then 2 feet, heat was my issue, but was manageable

That shouldn’t be a problem. I’ve had a 315 over a 2x2 area and it was a glorious lil patch.

i brought my room down to 12x8 from 16x15. (garage grow) I liked the results the 315s got me, but i wanted more bulk so, I bought the master pursuit from growers choice. Very light, VERY VERY bright.
