Guys come on...

Thermal imaging doesnt work like that.

You can have the air to be 30 degrees if you want.

The lights still put out the heat and thats what they look for. Viewed from thermal goggles, having the air cool but the lights HOT only works to make the lights that much more detectable...

duh.

If this is really a concern, your single best bet is to install drywall that contains lead. Its the same drywall used in doctors offices with xray machines.

You would have to build a box with this lead based drywall and that is really all you can do.

Hot air coming from the vents outside could be a dryer, a bathroom fan, anything.

There are specific color temps they look for and white is the telltale trigger color.

NOW, if you have an air conditioner blowing right onto the bulbs, that would reduce the heat signature but not the heat the filament itself is creating.

The signature of HID lighting is pretty hard to miss....lead drywall and concrete / brick is the only way to trap it...that I am aware of.
HARDDON Reviewed by HARDDON on . Temp prob. Hey guys, I got a temp problem and need to ask you guys a question. So the temp in my grow room is about 75 deg with 800w HPS. To reduce 75deg to 40-50 would I install a cool air hood for the HPS and a couple fans? The reason in doing so is that it has been really tight up here now that cops have been using thermal heating over house's to bust fairly large grow rooms, I want mine to stay about average if not a little bit higher. After all, this is my 9 clone room and I dont want it to Rating: 5
