How to Stop Helicopters Seeing My Crop

It isn't full proof , but it helps limit your chances of getting caught a little bit , but running your light's at night time helps imo.

Well where I live there is rarely a chopper out late at night , unless there looking for stolen car etc, any sort of thermal detection would get done during the day imo, due to noise from the chopper's.

Just my theory ofc , not saying it's 100% , but I feel it deffo helps provide some sort of cover , also blocking off the wall facing outside of your house with a couple of layer's of black sheeting(leaving about 1 foot, between the wall and the sheeting) , helps keep that area shaded a little and is usually alot colder than the none shaded parts near the lights( the area your growing in).

Also vent you room into your house not outside as that's a dead give away.

Most these thing's will only help small time grower I would imagine , big scale grows are a different thing I would imagine , when it comes to hideing them.

i agree w/ kanx. running light at night is most efficient. Not only are the temps cooler outdoors in the evening ( thus cooler rooms ) but as he said, electricity companies work during the DAY not at night. It also happens to be the most convenient time to work for me. my hoods turn on at 5pm and off at 5 am... Someone on here notes that the water cooled "ice box" that hooks up to your reflectors work great. I haven't seem them in action but on youtube, and the results are shocking. just my opinion....

I would think they would look at night ... wouldnt heat sigs be easier to see at night ? During the day all kinds of shit holds heat from the sun ..If I was a cop I would fly in the middle of the night . I time my lights to go out about the time I would normally go to bed ... dont have to worry about light leaks as much either ....

hi guys im wandering if any1 knows a site were i can get the ir blocker sheeting? and for the ppl with the small crops if possible grow in your kitchen in a tent / cupboard and to any aerial photos it shouldnt arise any suspicion as it will look like a cooker+extractor fan ( this is just a theory i have not tested yet ) will let u know when i have earned enuf to buy a chopper with thermal cam ahahhaha

I think something important to remember is that its the diffenence in temperature that shows up really easily... I heard last winter.. an old womans house was raided in our town because she had a small heater in her roof space to try and stop her pipes from freezing and the fuzz thought it was a grow... so maybe winter grows in cold countrys and a bad idea!!!!

Yeah I agree, ever touched the roof of your house/shed/etc during the day when the sun is shining? Theres no way they'd be able to distinguish between much of anything. They CANNOT SEE THROUGH walls, roofs, etc with FLIR, they're not the creatures from Predator, they can only see the heat of the roof/wall/etc itself and heat leaving a building.

Just out of interest, what exactly stops the "IR blocking" sheeting from heating up itself and then heating the roof up? It may block convective heat but surely it still absorbs radiant heat and heats up itself? If not why didnt they just cover the space shuttle in that instead of expensive, weak ceramics?

Id run my lights during the day, the police will get suspicious if your shed is glowing at 4am, not so much from say 7-7 for example because 99% of the population "do stuff" then that could/would likely make heat. (and FLIR works poorly at day because the sun heats EVERYTHING up, makes it hard to distinguish anything from anything.)

Hope this helps.

Well its not useless for say search and rescue, or tracking someone whos bailed out of a stolen car and hidden in a forest, but it is useless for detecting differences in surface temperatures of buildings like they depend on to find grows during the day.

EDIT: This is a document from FLIR.com, look how crap their daytime pictures are. You can barely make the guy out against the trees during the day...but look how effective it is at night.

bongsmilie i could reli use the site for the ir blocking sheeting please somewhere that i can buy it buy the meter?? please help :bigjoint:
and also could a dry ice machine be used to increase carbondioxide levels and would this help plants grow?? (still new to growing)

Sheet rock with lead based paint or I installed a cooling pad system in my shed. Basically I turned my shed into a faint swamp cooler by using fans that would bring air in thru the cooling pads and then back out got the idea from a local nurseyt had greenhouses set up this way. The cooling pads mask the air with layer on cool water which I reg the temp.
