To All,
I was wondering if anyone had detailed information on the use and accuracy of thermal imaging devices on plants of our favour. Time of day it would be used, I would assume nightime ? How close it would have to be. What other plants have similar signature, if there is any difference at all? I will do some research, any help would be beneficial for everyone. Thank you.

id like to also add to the question. What other detection methods are there? And how accurate are they?

Thermal Imaging is easy. All it takes is a hand held imager. The imager detects the heat and displays the "Thermal Image" as a picture. The cops are not walking around the dtreets taking thermal pics of peoples houses unless they suspect you are growing weed. In order to get a Search Warrant a thermal pic might be used as supporting evidence, but I doubt any Judge would sign a warrant on the sole evidence of a thermal image. Cops use thermal devices at night when the temp difference is greatest. If you are worried keep the temp in the grow area down by moving lots of air.

what about detecting plants outside? besides walking thru the woods looking for the stuff

Police also use helicopters with thermal imaging cameras mounted on them to find large fields of marijuana in wooded areas. The best way to prevent the "5-0" from finding your plants, if you grow outdoors, is to seperate them. Don't plant them all together, because the thermals can't really see just 1 plant too well, but they can sure as **** see 25 all nicely in rows.

As one of the cops involved in detecting and eradicating dope, I can tell you that thermal imaging is not used much for outdoor grows.

In the early 1990's when peace broke out, the DoD and other agnecies with hi-tech equipment that was suddenly under-used came to law enforcement and touted their wares. We tried everything from computer analyzed, false color photography, IR, and thermal imagining. None of them were very effective on outdoor grows.

Thermal imaging is still VERY BIG with indoor grows because of the heat generated by the cultivation.

Infra red (IR) and thermal gear worked best on outdoor grows when used during the heat of the day. The water lines, being cooler, than the surrounding terrain and vegatation show up very well, but there was no way to tell if they were domestic water supply or supporting a grow.

Perhaps the most insidious use of this spy technology was the attempts to use sensitive equipment to detect the minute amounts of radio isotopes in the galvanized chicken wire and the low level electrical impulses put out by batteries in the water timers. These happened at a level much higher than my lowly position so I don't know if they had any success.

Thank You,
I wasn't under the impression the plants actually had a different temperature than other plants, and that the thermal stuff was for the cooler temps as a result of watering.If the plants are scattered and the trails are not pronounced the thermal imaging is not really a threat.
again thanks

Brrrr... felt a chill on the back of my neck. Big Brother is always watching

I surfed around most of the day looking for information on the newest imaging technology and found a few sites with cool pictures from their latest gear. And they expressly state that their unit WILL aid in discovering marijuna production indoors! Scary thoughts but at least it is mostly related to large grow operations with obviuos increased heat.

Stay safe

Ganja Warrior what a joke. Hey when the cops burn a big patch of dope do you guys all go drinking? Backslapping and kissing each other? Hey do you have any trophy pics? Post some on the site. We all need a laugh now and then. We like the cop trophy pics where you are all dressed up in cammies. Can you take pics of growers hog tied and sprayed with pepper spray. You know the ones where you are all holding automatic weapons and grenades with the burning pile of dope in the background. There are more people growing dope than you could ever catch. Anyway I smoke weed and and proud of it. Who needs to police my free time. I hurt no one and contribute not one penny to anyone criminal enterprise. I smoke responsibly and am better for it. Marijuana will be just like alcohol soon.

I had a friend who felt safe growing outdoors because of spread out plantings. I told her that local police can buy several spectral ranges of sattelite imagery for $2.00 a sheet. Of course, police are not creative by nature, so they do not need high tech to burn crops. they depend on sneaky interpersonal tacticts.
i read a book at Linda Hall Library in Kansas City about 1990, the title "remote sensing of plants". Sorry, I forgot the authors. Two chapters were of great interest. One dealt with laser reflection spectography. The idea was to bounce a laser (either aerial or handheld, from platforms in a large orchard) and measuring the shift in the reflection off the ground to measure such things as nutrient content and moisture in fruit crops. The moisture measurement is made as different levels of retained moisture in the leaves cause the space between the cells to differ. Thick vs. thin cell walls are also identified. It takes little paranoid imagination to see that this has police potential. Many acres could be lased from the top of a grain elevator. Pipeline companies typically rent space on their inspection and mapping aircraft to law enforcement agencies. These make frequent fly overs of all areas. The other chapter of interest was about the capabilities of the landstat series of sattelites. These have microwave-length sesors that measure plant color and structure and nutrient content from space by the same technique as above. They have 3 meter resolution. The article dealt with identifying and cataloging phytoplankton on the oceans surface. If it can identify a single celled organism, how do you think your big bush fares? The lesson is, police look not for dope, but profit trails. They don't care if you smoke, but they hunger for the money drug dealing provides. They can always find plants. Love, sik mik.
