helicopter hovering

Of course these blocking films are reflecting the heat back into the room. Its not active or passive cooling; the heat still exists and in the wrong area for your grow.

anyway, the film works flawlessly. you can't see shit through it. remove the film and a 1000-watt hps bulb is so bright you can't even see anything but a white splash on the screen.

Now try it with a sheet of plain glass. Then put a piece of black electrical tape. That tape is gonna light up like no tomorrow, but the glass isn't, even though its got the light shinning through.

You use aluminum foil to calibrate local conditions.

Just look at these pics of a shot at glass (has low emissivity)
What glass shows is the reflected IR energy.
IR cam *ONLY* show the heat emanating from the *surface* of the object its pointed at. They do NOT see through things. There is a reason why houses have insulation; to keep the the inside temp isolated from the outside temps.
Did you take a shot of the roof?/outside walls (at the right time of day, yes it matters)

There is just as much heat behind the eyeglasses as on his face. Yet the glasses are reflecting the heat from in front of the glasses.

The guy waving in the window is the guy taking the pic. You see the reflected energy of the guy, not the heat on the other side of the glass.

Now keep in mind glass is an excellent conductor of heat. Drywall, fiberglass insulation, 2x4's, and siding aren't.

Yeah man! The TPB are the shit! Gonna have a marathon one of these days. Ricky is the reason I started growing. Figured if Ricky can, so can I.

(one of my fav scenes is where they are interviewing bubbles, and they blurred out the face to protect the identity of one of the cats)
I haven't been to SD in a few years.

timmmay... what stuff did you use? im looking to buy some ir blocker material to line my ceilings... please let me know, im a little lost.

IR does not penetrate metal or whatever you just said . period. no discussion.

yo its the mickey d's police come to steal your meat!

dont worry people back in the uk it more relaxed here get caught you get a slap on the hand and told not to do it again not many get jailed for growing personal cop looking more for commertial growers

No but, absorbed by and passed off/though to the other side. *any* heat gives off IR energy.
period. no discussion.

its the emissivity and reflectivity change, and thats whats gets picked up by an IR cam.
Different surfaces can change it *drastically*

drop $$ and buy a cam and/or take a thermology course and see for yourself.

no entiendo nada pero corre

in a show i saw regarding marijuana inthe states they hover to get heat signature reading to submit to judge the next day for warrant. If u heara helicopter means they are super close cause those copters are low sound engines so turn off all grow lights like 400w and more, and supple ment the garden with flurescent while the lights are off. That way they cant radings but if you hear them they probablyhave them already so ya. Like i said before being medical legal means nothing to you americans. The feds run the show not local cops.

they do that in the states it is called the FLIR (forward.looking.infra.red) it is against the law for the police to use them in order to get a warrant. they are unaddmissable in court so if you get brought down by the FLIR then more then likely the charges will be dropped
