Do I check at canopy level (scrog) or below it where it's shielded from the light?
Where do I check temperature?

If you can hang a thermometer on the wall of your space, right at canopy level, you'll get a good indication of the conditions your plants are experiencing.
Anywhere from 72 to mid-80's is an ideal range.

I thought I had read somewhere on here that I didn't want it to be in direct light, right under the 600?

Orly? It's 18 inches away, still being bathed in a lot of light.

Alright well my cab is running about 80-85 on the bottom, and up at the canopy, 90-95! I just turned the ballast from 600 to 400 and the temp is dropping...I figured that a 500 CFM fan would be adequate to maintain low temps with a passive intake, it's only a 40 cubic foot space, so it's got a ton of negative pressure. Any thoughts on why the temps are still soaring? The fan has good suction and I can feel my hand being sucked into the cooltube.

Temps are at 85 and dropping..wow that extra 200watts adds a ton of heat! I think that the cab is just drawing warm air in from the top of the room, and when I have it sealed it will only be able to draw air from the floor where it's much cooler, hopefully allowing me to run 600w.
