Thermal Image resistance???

[smellybottom]

Can anyone tell me any good methods of thermal Image resistance?
I heard something about lining your grow room with rockwool and mylar?
Is this a load of bullshit or does it work??

[dylan]

don't know about that, but i have heard of some type of heat blocking foil to line your celing with. though i don't know where to get it. i saw it in a pot tv show.

Thermal image?

Sorry, but can someone explain this to me?

I've heard of a system where the police can scan your house and see and large amount of light/heat being generated...but I honestly thought that was a loud of shit. It seems silly that they are even ALLOWED to do this. Invasion of privacy comes to my mind, I think.

[dylan]

they do not see light (unless you let it leak out), but they see heat. it's only sercemstancial(not shure how to spell that)evdence, and would not be used unless they knew or had a good idea what was going on.

[rnf232s]

First of all the cops dont go around searching for houses with high levels of heat randomly. They would have to have reason to. Also a small grow area wouldnt yield enough heat to really do anything anyways too. They couldnt come close to showing it was a grow room.

[UserName AlphaNiner]

Well, a large amount of heat concentrated in one closet sized area would give them a pretty good idea of what is going on.

I think it's bullshit, still. Invasion of privacy. They should not be able to search my house in ANY way without my consent. I don't grow, but I think it's utter garbage that a police officer can scan my house, without me knowing. I mean, heat is used for a lot of other things, too. X_X

I actually heard from a friend, originally, that someone in my city got busted for having a couple of houses full of weed....but he got caught because of this thermal thing. I didn't believe it at first, though.



So, tell me more about this....will they do anything for 1 closet full of plants? Get a warrent to search your house or something?

Thanks...pretty much solves my questions. Now... a viable reason for searching houses would be? High traffic (suspected dealing) Nieghbors tipping or past records?

[rnf232s]

I dont know for sure, but to go to the extreme of sending out things to check the heat and stuff I would think they would have to have some good reasons to. If people dont know and stuff I doubt they would unless they suspected you of growing. Maybe if you had a large grow room and somebody knew and got busted and were a rat and told the cops they might check out, but other than extremes like that I honestly doubt you are in trouble if you just dont let the world know about it. A personal grow room I definately doubt the cops would bother you ever if you never told anyone, even if they used heat reading stuff.

[SomeDude]

In califonia and hawaii they used to fly helicopters around with thermal imaging looking for growhouses(thus searching random houses) in order to get a warrant, but I believe that was ruled an unlawful search.

As for the material used to line your roof, I believe its aluminized mylar, the same stuff used to make thermal survival blankets. They're also carried by some forest firefighters to cover up with if they got surrounded by fire.

However, the military did some testing with this stuff to see if it could hold in body heat enough to evade enemy thermal imaging, and they found that the mylar just heated up to near body temp and didn't do any good. Perhaps if you used it to line your growroom the same could happen. But in the case of a grow room the heat is being tranferred by radiation rather than conduction in the case of having it against your body, so that may make a difference.

[Closet Drifter]

Someone told me that if the PG&E notice your bill jump up them thats enought to search your crib :mad:

[litespeed]

get a small poll and run the pump so long all a day add a lot of lights have them on put in gas water heater but use a lot of Ele. hot water, when they come there is nothing they go away.

[NowhereMan]

they do look for it,depends on where you are ,How they look.
some places using things like this now
so ya be carefull

Hey this is real. the cops do this on a reg basis. they usually do it at night but if your lights are on during the day it is hard for them to catch the heat from your growroom. No lights at night unless you want to be busted. although there are certain flyzones they have to stay in as we all know, hopefully! they always fly over my house at least once a week and i live in the suburbs.

hey man a closet will should not be vunerable. no one should even know that you are growing b/c even your best friends will rat on you sooner or later b/c you have money and they dont and they are jealous. Oh yeah "3 can keep a secret if 2 of them are dead." Ben Franklin

Blanket thermal imaging or thermal imaging without other probable cause has been ruled unconstitutional in the United States. Police cannot fly around with thermal imaging cameras looking for grow houses. They also cannot drive around your neighborhood looking for your grow room with thermal imaging cameras.

A small personal grow will likely not be discovered by thermal imaging alone. Police will likely discover or fabricate some other evidence before using the thermal imaging equipment to locate your grow.

Nonetheless I remain fearful of this equipment. Worm's Way stores have thermal imaging blocking material available. It is expensive, but if it provides some peace of mind it is worth it.

[dejayou30]

Just don't put the walls of your grow room on the outer walls of your house. Leave a few feet of space between your growroom wall and the outer wall of your house. That way, if they try to scan your shit, the air around your room will be the same temp as the rest of the room and there will be no cause for alarm. But like everyone said, thermal scans are illegal without some kind of probable cause in the US.

I'm not entirely sure on how the law works in the states, but I've head of a fair few people in the U.K that were caught by thermal imaging cameras when a police helicopter was following a joy rider or speeder, though of course this is just another lie they could use to give them an excuse to search your house, and so if you are going to grow anything I'd be more worried about people knowing about it on solid ground.

[denialisback]

There is a simple solution to thermal imaging resistance. Make sure that you are extracting enough volume of ambient air from outside into the room. This way the only thermal signature picked up is that of the ambient temperature.

i.e. (exactly) reads out as a normal heat sig. they are looking for hot spots only. not whether someones got air conditioning in a room or not got their heating on :)

hopefully you are a legal grower like most of the MMJ guys and this will evade nasty situations arising!

insulate, insulate, insulate.

Build a cab out of foil faced foam board, keep it a couple of feet from any exterior walls. Leave some space between the top of the cab and the ceiling, and insulate in the attic over the room with the cab.... at lease R-29.

C3 sheet

From the Netherlands, this super reflective mylar also has the interesting characteristic of being 90% thermally insulating. Use the C3 sticky tape to seal around corners and electrical sockets. Beware of copies ! Many shops are selling FAKE C3.

I'm not so much worried about the thermal image as much as the pattern of energy used. I had an outragous electric one bill time so I asked the elec co about it and they sent me a report on the electric usage on an hour by hour basis. :eek: I guess there is some sort of device that sends my electric usage to a satallite or something every hour. (and this is in B.F.O. :D) I've been a bit reluctant to grow indoors since then. I mean if you have high voltage lights on a timer it really would take much a program to id "unusual" energy usage patterns.

Maybe low energy L.E.D.'s might help but still if they are on a timer that has got be easy to spot. I'm thinking maybe a sky light window might be the way I go next time. Natural sunlight but still indoors away from critters and other nosey pests.

Easy enough to fix the electrical usage..... switch all the lights in the house to CFLs, use CFLs for grow lights, and start the cycle at the beginning of summer to coinside with air conditioner usage. Have the A/C serviced by a certified Master Tech to get it as efficient as possible.

*NOTE* once you start your lighting cycles, don't stop.

I use 2 sets of lights.... I am not worried about the hourly thing as Mississippi Power doesn't have those technologies for residential(yet). The first set is 10 CFLs (23W) over the top, and 10 dual tube 4ft fixtures. In veg, I run the CFLs only on 18/6, then once transplated to the 5 gallon buckets, I use both sets of lights on 12/12. It all kinda balances out in the end.

Are you sure about that, as far as I have heard all states use the flir system on the ghetto birds. And most States if not all have a small unit that fly around in small aircraft and that is thier only mission to find grow ops using the F.L.I.R. system. (thye have other descriptions in their mission statment, but mostly it is bullshit) In my small city I see the plane flying around every morning at about 0500, in the northern areas the dea has a blackhawk helicopter and that is all they do, all day every day.

Managing heat is done best buy insulating, and lows, home depot has many options for insulating, the pink stuff works well but use alot. We insulated a house once with over 4 feet of the pink stuff and about 2 feet in the walls and when we turned on the lights in the early morning. with a FLIR scope their was still a heat signiture but no more than the rest of the house with regular lights on.

thanks for the spec's on the CFL's. :greenthumb: yeah, i was thinking CFL's would probably okay, too, since I already use a lot of CFL's for outdoor lights, etc. I'm probably safe to grow, I don't think they really monitor at that detail unless you request it, but then again, its two years to life for cultivation here :eek:, in Oklahoma, so I tend to be a bit over cautious. :jointsmile:

I have grown with CFL before and had pretty good luck but I could have used some more lights, I think. I might give them another shot. that and the sunlight. I've got a buddy that grows some really nice juicy plants just growing in the windows. its painfully slow but the plants look great. :greenthumb: I think my next project may be a hybrid of CFL enhanced natural sunlight. :jointsmile:

[Mississippi Steve]

here's a pic of what I am talking about. I use a regular box fan to control the heat and for ventilation inside the cab.

[boaz]

^ cool. that is a work of art. :cool: the plant, too. :jointsmile:

I agree, around here me and a few others noticed a small unmarked plane circling the city bout 2 or 3 am, and as far as "invasion of privacy" the feds stay out that mess by passing the info to local police dept, then the coppers do thier thing going on an "anonymous tip" lots of people getting busted on these "anonymous tips" and when its court time during the DISCOVERY part of it, all these details are supposed to come to light, but somehow remain anonymous....that way the feds stay out of the whole thing and local PD gets the credit for the BIG BUST...happens all the time so don;t be naive, thinking they have no right to fly over your house and take thermal pictures....thanks to Bush and his patriot act the fed does alot more than we would like to think

[geoluv]

^ that would just look kinda like a tanning bed on its side from a thermal camera.

the biggies are the hid bulbs, im pretty sure there isnt anything else in a normal household that gets as hot and is the same shape as a HID bulb.

9 out of 10 grow ops get raided because someones lips were too loose. usually they are trying to bargain their way out of their own mess and this situation can make even the most loyal of friends flip, this is why you tell NO ONE, its best for everyone.

[yokinazu]

i got a few tips to avoid thermal detection.

1. centralize the grow area. put it as close to the centre of your house as possible. the further away from walls the less chance heat will leak out.

2. get as close ,or below, to ground leval as possible. the more house above your heat souce the better.

both do one thing put as much barrier between the heat source and the outside walls of the house. think about it its much easier to see an attic grow room than a basement grow when flying over with thermal imaging equipment.

3. insulate. this is also kinda the same principal as above but the better insulated the house the less heat the house losses making the whole house appear the same basic temp all over.

contrary to popular beleif thermals cannot see "through" walls but can detect hot spots. the idea is to diipate the heat into the rest of the house as quickly as posible.

4. mimic natural light cycles. have your day cycle running when the sun is up and the light out at night. most thermal imaging is done at night so the surrounding area is cooler making it easier to see the hot spots. if they are flying over at 2 or 3 am even in the dead of winter in minasota you can set setyour light to bring on the night cycle before then. wich means that if your lights are off they aint producing heat wich aint makin hot spots.

basicaly just use a little comonsense and planning on the location of a grow as much as any other part of it.
