Conflicting Question

I'm running a 600w & 1000w air cooled hoods together in a straight line,,, both connected to each other,,, Question is,, should I have the 600watt first,, instead of the 1000watt,,, so not much heat is blowing on other bulb,,, vs,, having the 1000w first in line blowing the heat into the 600watt?

I’d put the 1000 watt in the back if there is going to be empty space behind the plants

I'd say you did it right.

Thank you
