is this true?

Sorry i didn't have time to read all the posts.

YES the reflectance of Cannabis is used by police to find outdoor grow ops
they can actually find very small ones

What they do is they have some sort of camera that looks for the "reflectance" it just means the spectrum reflected by the plants tissues.

Heres a chart of cannabis's reflectance and other plants.

it's very different. Different enough they can use it.

harris,

If you're paranoid about that, set up a HUGE indoor grow of legal plants and shrubs. Then if the flying pigs see your heat signature and try to bust you, they'll be pretty embarrassed to break down your door and find a lot of sage plants.

Once they leave, start growing weed. They'll never bother you again.

That is such a good idea, Rig up a bunch of lights, pump out a big heat signature. CAll in some things to the cops about your house.
Then have a bunch of tomatoes. After they come, start growing

non living objects dont generate heat. maybe your ice melted because your friend removed the insulation?

some of you are very misinformed. the infrared that police use to look for grow ops is used to detect hotspots created by the HID lighting used to grow weed, not the plants themselves. cannabis plants dont give off anymore heat than any other variety of plant.

sorry babe, but i have to do it...

YOU, sweetie, are the one misinformed, as stated in a previous post, the infared that the piggies use detects infared REFLECTION, which is a type of heat (i.e. warm spectrum, cool spectrum) when the choppers are flying, they are primarily looking for OUTDOOR GROW OPS. not indoor. this is why they fly twice a year, late spring and fall; harvest season (yeah, i know; the bastards...)

if you don't believe me, search for infared arial photos/marijauna... you'll be able to see the individual pot plants yourself. the MAIN reason they don't get most outdoor grows is because of the narrow path of the infared. even flying 24/7, they couldn't scan every square foot of earth; it would take them years just to clear everything once!

also, tobaco will spontaneously combust in barns whilst drying if not properly ventilated because it produces SO MUCH HEAT!

i just wanted to get you straight, so it doesn't come back to bite you...i'm not trying to be a bitch, i promise

love, kp

If that was true then all plants would also retain heat. Their is no special metabolism in cannabis that raises its heat any higher than ambient temps. Test it yourself; stick a thermometer into the plants rectum and see if there is any difference with air temp.

Cannabis plants give off a unique infrared heat signature that any trained operator can recognize. a Thermometer in the soil wouldnt detect anything, its the heat that is being given off by the plant itself that is what they are detecting.

Police were also using this technology to detect house growing operations by looking at the external walls of houses, but the supreme court ruled these as illegal searches and police can no longer use it in that method.

The high power lights that the dopers use to grow the drugs generate a large amount of heat. The criminal farmer must vent this heat or the plants will get to hot. We can find the unusually hot exhaust pipe in the roof or the hot room in a house that seems to be hot and cold on a regular cycle (hot when the lights are on cold when they are off). taken from

and from http://www.predictive-maintenance.com/marijuana.html

spectral contrast between marijuana and other plant canopies appears most significant for green, red edge and short wave infrared wavelengths, however, isolation of marijuana canopy spectral signatures during land cover classification may be difficult using visible-near infrared systems

and pot makes you pregnant.....you are the biggest idiots I have ever seen on a forum. Is the age average here 9 years old? You morons shouldnt smoke pot, you are fucked up enough.....

yeah? and how old are you, asshole? coming in with a dumbass remark like that makes me want to assume you're just some ignorant teenage punk. how bout offer up some contradictory info; then you may have some ground to stand on before i push you down. read my friggin college course, dick head...

sincerely,
one pissed of princess

hey, sorry for the 'tude', but shit like that realy gets my goat, ya know?
