Yah, that's why they use thermal imaging for detecting fires outdoors,... because it doesn't work....

Weed has a specific signature, not unique but specific. Thermal imaging CAN detect an outdoor grow. I can understand the wish not to believe it, but it's true....

I agree with the warrant issues, but you need to understand how the real world works as opposed to the paper world. On paper they need a warrant. In reality they locate the grow, never mention it, and then find another pretense to go to that property, imaging long forgotten and never spoken of.

I'm calling shenanigans on this.

Cannabis growing outdoors CANNOT be seen with thermal imaging. FIRES ARE HOT, which is why thermal imaging can detect them. Outdoor cannabis grows can be see from the air BY THE NAKED EYE. It has a very recognizable outline, which is how they spot it.

Cannabis plants are not "hot" enough to distinguish from other plant life from the air with thermal imaging. It isn't a matter of not wanting to believe it, it's a matter of knowing it simply isn't true.

What they're searching for with FLIR or thermal cameras is heat being pumped out of homes or radiating through poorly insulated ceilings. Plants growing outdoors do have a heat signature, but it's impossible to distinguish between a cannabis plant and say, ANY OTHER PLANT.
 
Thermal imaging is the same as heat signature..... so you don't think weed puts out a heat sig? You doubt that a piece of hardware with an accuracy of 1/2 degree won't help identify that sig?

Fire away... shoot me down, if you can...

IT's ok, at least you and me know what we're talking about is right.

You cant see a weed op with the naked eye, it's just green like the rest of the plant life - it's the difernce in heat sig it puts out which is what they look for. For instance, rose bushes have a very similar heat sig to cannabis.

some people just dont have any idea do they crackerjax

Absolutly everything you just said is void, inaccurate - WRONG.

Why post for no reason man? Whats the point? Learn what your talking about before you bother wasting space.
 
We used FLIR in Afghanistan and it can't see through walls. What the cops look for are houses with more than one heat exhaust source, example being a dryer vent and another. The solution is to blow the heat under your floorboards, into your attic, or simply blow it back into the house, never blow it out a window for instance.

I've been in the Military(AF). :roll:

I'm going to have to agree with doobnVA.

I've seen many photos of plants taken with FLIR cameras, they typically look like incomprehensible blobs. Especially during day-light.

Most plants have no way to create heat(other than very small amounts from their 'bodily' functions). Well under 1/2 degree. Probably not even 1/10th.

So, anyway, this technology would have to be based on reflected light. During the day this would be impossible, too much interference from the sun. So unless they have a 'spot light', and fly around at night using it.... It doesn't seem likely that they use FLIR for outdoor detection of marijuana plants.

Now then, detecting the people's FLIR heat tending the plants seems a much more reasonable/plausible way of outdoor detection. And on a large op, this seems to be a given.

Prove it? All I've found is conjecture and hearsay on the subject. Zero proof. So where's the proof that has got you guys so sure?
 
No, Tree, what I said was their accuracy is within a 1/2 degree. Meaning the new sensors can tell the difference between 98.0 and 98.5 F (example). That's pretty darn accurate. A large outdoor grow is going to create a uniques signature. Large grows should be easy pickings for this technology.
 
Plants don't give off heat. thermal imaging isn't the same as infrared imaging.

You guys are most likely thinking of spectral radiance, which is the how the light reflects off of something. This can be measured with a technique known as "remote sensing".

Here's a link to an article from 2003 on how remote sensing *could possibly* be helpful in identifying outdoor cannabis grows (at the time, they couldn't seem to distinguish between cannabis and other herbaceous plants, I don't know if they've had any success since then because I can't seem to find any documents published later than 2003).

actually your buddy in the military is semi correct not so much the military does flyovers but dea does some special volunteer groups help out but they flyover national parks and forests. us supreme court has ruled the thermal imaging of a residence is an invasion of privacy therefore is not allowed to be done and is inadmissable in court norml.com

we're all a lil bitter, especially first wave oif guys, just because you came out with a bad attitude doesn't mean you need to shit all over the rest of us, i dont care if you got a dishon or oth, if your a vet, you shouldn't be shitting on all of us.

amen the vets of america today are the reason why we can fight these unjust laws that prohibit the use of our medication if it wasnt for men like my friends and I remember if your reading my message thank a teacher if its in english thank us soldiers!!!!!!!!!!! hoooahh

But the facts are they are done. it is simply a matter of finding the grow op and then finding ANOTHER excuse to check it out. The heat sig won't ever be mentioned to the justice dept.

Links or it didn't happen. :lol:

I think defending your nation is great, but 'wars' where massive civilian causalities are incurred(eg. "shock and awe" air raids on civilians). I don't agree with that.
 
You end up getting busted because the thermal imaging can pick up the hot air venting from your grow room from something like a window or some other place there shouldn't be a heat bloom. If you need to vent a grow room then run the exhaust through your dryer vent or under your crawl space if you have no basement. There are many ways, you just want to make sure that the hot air can dissipate before it goes outside if not running it through your dryer vent
