Stunted growth? Temps?

Really?
I am just learning a bit about LED.
I've heard that before; but when I ask our local guru he tells me that as long as temps are above 75F its all good. But in an HID room, 75 degree ambient means 80+ at the canopy. So, what you're saying makes sense, logically.

I'm trying to figure out what's what ...
So I need to keep ambient (room) temp at 85F or so?
