Build it underground. Seriously, you'll need at least four feet of dirt over the whole building to block the thermal signatures. You can call it a bomb shelter, cause that's where the bomb is sheltered. Other than that, you're fucked without a medcard. A strong heat signature coming from an out building that is not meant to be living space looks suspicious indeed. Remember, you will always be better safe than in prison.

How do I mask my heat emissions?
Note: Small grows (under 2000w) would probably not emit enough heat to warrant the effort or expense.
Note: Reducing grow room temperature will reduce heat emissions; however, the grow room will still be warmer than surrounding basement rooms.
This technique creates a false wall to contain cold air. Interlocking rigid foam panels prevent hot grow room air from contacting and warming house walls. Cold air is blown into the gap between the foam and the walls for maximum protection. The wall?s exterior will appear ?cold? to an IR camera, indicating a negative for internal heat.
· "Partial room" (insulate exposed walls only)
· "Room in a room" (entire rooms are insulated)
*Floor. Concrete foundations absorb heat readily. Build a sub floor to raise the entire grow off the floor.
*Walls. Use interlocking 1.5 or 2? foam insulation along all exposed walls. Place the insulation 1-4? away from walls, fit foam panels from floor to ceiling (some cutting may be required), and blow cold air into the gap. Seal seams and corners with tape. Cover walls with Mylar to reflect heat back into the room.
*Windows. Windows are essentially uninsulated, so you must fill the gap with insulation. Draw the curtains/blinds, add black poly behind, then add insulation.

Even if it is well insulated against letting heat out, you still have to do something with all of that heat. Buddys idea of having an air gap in the roof, with constant air flow through it is a good one. You could also filter the hot air to remove that chronic scent, and pump it into your house to help with the heat bill.

No just line your line your sealed reflectors with IR insulation. It blocks 97% of light from IR scopes.

75 bucks from CAP for a 4' x35' swatch and it doubles as insulation

Not gunna happen pal, i've been told the police helicopters dont even pick up heat signatures that well unless its over a certain temp. What they do is they rent helicopters off electricity company's that use a very expensive camera to detect breaks in wires that are underground and this is how they detect heat from crops, otherwise nobody would ever have been able to grow in a loft/attic because they fly over a vast area.

Ya ya, I dont think your problems the police, but keeping the plants at a reasonable temp in an outbuilding.

The IR blocker sheeting does infact work. The only thing is initial expense. every sq. inch of your cabinet, tent or room has to be covered with a 2 inch overlap between sections. All seems should be sealed with aluminum tape. IR blocker sheeting is best used in new construction. If your worried about it why not. just know that its not cheap. and 1 sq. inch being uncovered defeats the hole project.

dont talk crap. if a helicopter using a thermal imaging camera spots you, you will light up like a fkn christmas tree, and your body is only 37c ( 98f ), helicopters are not hired from electric companys, ( the companys use them to check for shorts and heat on the cables of pylons where huge voltages are carried etc) thermal imaging cameras were borrowed from them by the police to use for testing to see if they were useful for people in trouble and in the battle against crime.
now all police helicopters are fitted with them as standard equipment.
they are especially useful when people have fallen in to swollen rivers etc, a person or body can be spotted very quickly if the helicopter is there fast enough to look for it.
they are especially useful in hundreds of criminal activities, including the use of a night eye in the sky. they can even spot a person hiding in a vehicle as the outside shell of vehicle will start to show heat, if you hide in a wheelie bin for 30 seconds the bin will glow like a lamp.
they are used occasionaly by the drugs department to search for illegal cannabis farms, roofs, windows, even roof tiles around roof vent pipes can glow with excess heat.
not every one who is caught with a cannabis farm has been grassed. ( if you excuse my pun ).
if you show heat you COULD be caught. do what i do. immediately correct any heat problem before you regret it from your prison cell.
sometimes paranoia is your friend. a natural reaction, there to stop you getting nailed.

try using a reverse infrared parabolic dome emitter.

What are you talking about "don't talk crap" ??????????????
If you read my post properly i said "I've heard" not saying its 100% truth but its again WHAT I HAVE HEARD!!!!

I use an ICEBOX water cooler for my 1000w along with a chiller. The icebox removes all the heat(minus the little bit coming off the glass), and brings the exhaust temp to 75 degrees with a 65degree chilled water. Even my hood, stays cool to the touch and emits almost no heat. Why worry about the heat, when you can remove it all together? You will use a little more in electricity, but you can also use this as an air conditioner.

ive got a dark room grow tent that is 2x2 x 5' tall and ive got two 150 hps lights in there with a intake fan and a exhaust fan blowing the heat straight into my room, i mean honestly its not enough heat to make me uncomfortable, but for the smell factor i have a fan in my window blowing out the air from my room, im in the second story of my house and last night i had a plane, not a chopper fly over my house at about dusk and it continued to do this two more times. now im wondering if possibly they had a ir on a plane instead of a chopper considering im in a rural area and im in a farm county. could anyone tell me if im just being overly paranoid or if its a legit concern. also ive never been in trouble with the law and no cops have ever been here. just adding that in. any help would be greatly appreciated

i would think that an RPG would be handy in this situation.

you can call it a bomb shelter..................
bacause that is where the bomb is sheltered...........
are you one of those muslim fanatics................... LMFAO...
and did you get your pilots licence for taking off only.
