if you're growing outside, can't the police do a helicopter sweep and see the weed by using a special thermal camera thing? if so how do you hide your weed from the 5-o?
Police?

yes, they can and no you can't hide them.. you can space them out and grow less that 25 or so. that seems to be a threshold.

so if im growing only like 5 they won't be able to find them?

They may still "see" them...no guarantees, but 5 doesn't pay for the heli gas and won't make the news...so you are probably safe.

Nah, the thermal imaging cameras can pick up the reflective signature of the plants, all plants have different signatures so your best bet is to plant next to similarly coloured plants.

me and a few friends are going to grow like pink rosebushes 
, he said rose bushes are the best to hide them, but i'm like i dont think it'll hide it still.

yea we good friends, he helped me grow em, so it really cant be going south, hes going to be moving soon so yea no greed will get into play. and my other friends just wanna smoke it with me lulz, and that dont really bother me cause i wanna smoke it 
but im also thinking about telling my other friends that i threw out the plants so they wont go around telling everyone im growing the shit.

weed has its very own signature...one of the reasons they fly those helis which are expensive as all get up to operate. They are looking for MAJOR growers and houses.

No no no no, weed does not have its own special "heat signature" and it doesnt glow bright purple in the cops special "weed seeking camera" To look for plants, they always look for heat signatures coming off grow lights in houses using whatchamacallit thermal imaging. Outside they look for large plots of weed growing, and those arent too hard to spot by eye.
The man above is correct. I have grown plenty out in plain sight, and they will just fly right over. Marijuana is a typical plant, it grows just like any other. It has the same insides as any other, it goes through the same process of photosynthesis as any other. It is a mean green plant. Marijuana also looks just like (Oak Leaf Hydrangeas[I think that is the name of the seven pronged leaf]) when they are young. Being that I have a huge backyard full of Hydrangeas and haven't gotten busted for the cultivation of Marijuana I would say you are OK to grow 5 plants outside. Still unless you are in the woods...I would hide them.

Pretty much nailed it here. Get fly by's where I grow every so often. They will circle and then leave the area moving on to find more plants. This is a DEA heli also, so you keep it under 10 and your good to go.They may still "see" them...no guarantees, but 5 doesn't pay for the heli gas and won't make the news...so you are probably safe.

I have 5 and they didn't land to grab my girls. Basically, its not cost-effective for them to land the heli, chop down the plants and fly away if its under 10 plants. Saying you get a solid Oz per plant (if not more depending on grow area) and they only got 10 oz which sure as hell no one will care about if they hear it on the news.
Thats why you only see "HUGE Marijuana Growing Operation Busted, 200+ plants found and confiscated" in the news, not "5 plants found growing in field, No one charged for operation." lol
All publicity, and also I would say IMHO that their main weapon for finding it is seeing it with their own eyes, not some hyped up sophisticated wavelength infrared marijuana detecting device. Just my 2 cents.

While I dont think weed has its own special signature, I do believe it is much more reflective of IR then other plants (due to THC? Possible purpose of THC?).
Some greenhouses have a reflective IR barrier so it can get in, but not out.

PROCEEDINGS OF THE OFFICE OF NATIONAL DRUG CONTROL POLICY PROCEEDINGS. Interpretive Summary: Successful detection of outdoor illegal Cannabis cultivation with remote sensing would be of considerable help to law enforcement agencies. It is assumed that remote sensing will rely on the spectral signatures of Cannabis plant canopies as the primary indicator. The spectral reflectance of Cannabis was examined using laboratory, field and airborne measurements. Results thus far include: 1) leaf and canopy spectral reflectance of Cannabis exhibit characteristics of other green plants, 2) nadir spectral signatures do not have stable, unique absorption features suitable for a reference signature, 3) the "emerald green" (blue-green) color of Cannabis results from specular reflectance of blue sky light and small particle scattering from microscopic structures on the surface of Cannabis leaves, 4) spectral contrast between Cannabis and other plant canopies appears most significant for green, red edge and short wave infrared wavelengths, 5) spectral contrasts between Cannabis and tree species appear greater than spectral differences with other herbaceous species, 6) isolation of Cannabis canopy spectral signatures during land cover classification may be difficult using visible-near infrared systems, and 7) researchers investigating detection technologies must be kept aware of the trends of growers to conceal sites. Analysis of the essential elements of information associated with illegal Cannabis cultivation offers other possibilities for detection with remote sensing. Ultimately, remote sensing will be most effective when used with a probability-of-occurrence/Cannabis cultivation site prediction model from the Counter Drug ¿ Geographical Regional Assessment Sensor System (CD-GRASS). Technical Abstract: It has been proposed that illegal marijuana cultivation can be detected using remote sensing. The approach would be to key on the unique blue-green color of marijuana plants reported by law enforcement aerial spotters. The spectral reflectance of marijuana leaves and plants was investigated. Results thus far include: 1) leaf and canopy spectral reflectance of marijuana exhibit characteristics of other green plants, 2) nadir spectral reflectance does not have a unique stable, absorption features suitable for a reference signature to key on, 3) the "emerald green" (blue-green) color of marijuana results from specular reflectance of blue sky light and small particle scattering from microscopic structures on the surface of marijuana leaves, 4) spectral contrast between marijuana and other plant canopies appears most significant for green, red edge and short wave infrared wavelengths, 5) spectral contrasts between marijuana and tree species appear greater than spectral differences with other herbaceous species, 6) isolation of marijuana canopy spectral signatures during land cover classification may be difficult using visible-near infrared systems, and 7) researchers investigating detection technologies must be kept aware of the trends of growers to conceal sites.

Technically you are correct, but they are keying in on its signature none the less. It is not a needle in a haystack out there.

Even if they did have the spectral reflective b.s. its new technology and isnt going to be on every heli they use, they just look for the giant fields of it, keep it hidden away from water and roads, dont leave any paths and try to use only small openings of sunlight, like where a tree just died

Well that just isn't true... I have had multiple fly by's and I am deep in country Floriduh. We get FLIR Fish & game out here. Small grows don't have much to worry about. In my case they were "probably" scanning houses. They do multiple fly overs on different occasions and look for differences in heat sig's.

They can't use a infrared camera to find your weed if your growing next to other plants because those plants are producing heat too....
