Double Stack Temps?

[growclean]

So we are running a double layer vert in our flower room. Meaning that we have two levels of lights in the room. I have a thermometer at the top and bottom. The temp difference runs about 6 degrees. So if the top is 79 the bottom is about 73. So my question is:

Assuming that without CO2 that the optimal temp is 78, is it better to be at 78-80 up aboe and 72-74 down low, or more around 81-83 up high and 74-76 below... or otherwise. I am running AC and vent fan to keep the temps. So I can probably do what I want. About to add 2 more 1500w lights though, so we'll see if AC can keep up...

Thanks!

Thanks... So high 60 is better than low 80s eh?

My veg room has been running in the 60s lately and is still doing well, although, I keep meaning to bring a supplemental heater out. They look good in there though, so I kinda figured. When I hit over mid eighties last go around in flower all hell broke lose.
