Medicinal-hermit Posted October 26, 2012 Share Posted October 26, 2012 Hi there bud. so you are on a right track with the insulating. NOTHING is more important than where you vent your hot air. IF you can and you take the time to do so. i would personally make it so i could vent my heat into the ground.(thought that is just me) everything else should be ok. if you are looking to do this stealthy and fast. i suggest a good auto flower. 1 Link to comment Share on other sites More sharing options...
bozoph Posted October 26, 2012 Share Posted October 26, 2012 only way to know is to buy a flir. lol jk. a 250 watt bulb is not that hot. with your precautions i think u will be fine.but u may need to find a way to cool your exhaust air. to stop your shed from looking like a fire breathing dragon in the flir 1 Link to comment Share on other sites More sharing options...
Medicinal-hermit Posted October 26, 2012 Share Posted October 26, 2012 also do you live close to people that would say something because smell will be an issue. i suggest buying some carbon(should be cheap) you can make a homemade carbon filter. i did so with an inline fan some screen from a door.. and carbon. 1 Link to comment Share on other sites More sharing options...

budman1988 Posted October 26, 2012 Author Share Posted October 26, 2012 oh btw if anyone is unaware about flir they can only pick up the first thermal signiture it picks up so anything behind it is invisable so to speak.well so says the flir designers and manufacturers Link to comment Share on other sites More sharing options...
Dust Posted October 27, 2012 Share Posted October 27, 2012 are the use of flir that often in your country? it's rare to see people worry about beeing seen by IR around here, but you're right, better be safe than caught!They gave you all good advice and don't see what i could add, the carbon filter of course will be essential for you i think, and check on the forum about the ONA gel or any other gel to catch odors, better have 2 protection than one Good luck man and share that room with us when it will be launched Link to comment Share on other sites More sharing options...

budman1988 Posted October 27, 2012 Author Share Posted October 27, 2012 one other thing, i keep reading about mylar foil sheeting being flir proof, is anyone aware that this is true or is it just another myth? Link to comment Share on other sites More sharing options...
Elektroski Justovski Posted October 27, 2012 Share Posted October 27, 2012 If u paranoid don't smoke pot. lol 250 is not much, in non heat tent in non heat room it go up to 16c. Link to comment Share on other sites More sharing options...
lamsbread Posted October 27, 2012 Share Posted October 27, 2012 Due to austerity cuts the police heli numbers have approximately halved in the uk still not perfect but 50% is better than nothing.standard mylar not really any use , better buying more heavy weight aluminium anti dtection foil, which should still be used with insulation for best results, probably not nescessay for you coz of you small light and ample insulation.This can be pricey £15 a meter on ebay.A total of 5cm of insulation is good and should do the trick make sure you fill the gaps an expanding foam filler,don't want any chinks in your amour. Hiding exhust is the most difficult part, you could use an ice box heat exchanger (needs a source of water which chills the air as it passes through a small radiator) someone has made a diy one on rollitup.vent down into a sewer if you can this is the simplest option but not always possible.This might sound a bit odd, but get a small chicken coop and run and buy a couple of chickens vent into the coop and this will keep them warm and there is nothing suspicious about a warm coop (this aint for everyone i know!) one plus is you get eggs too!Vent into a near by green house , during the winter months i used a green house heater to stop the frost damaging my citrus plants. if you do this make sure you have some evergreen type plants in the green house or it will not be convincing , warm greenhouse no plants! (make sure you use insulated ducting and make sure is well hidden/diguised)running a long length of ducting under ground which will cool the air before it emerges (obviously not to deep, your not mining for coal, make sure the ducting doesn't get crushed).A good carbon filter is good,also as you said adding ozone is even better. Cheap ozone generators can be bought from aqarium suppliers and dont have timers which limit the time ozone can be produced (this is what you want) they have a small airpump and air line which can be inserted into the ducting post filter.If you can afford to rent a flir camera then do so, this will show you exactly whats going on and wether you have covered all the bases and how efficient your anti flir methods are.Small heat signatures are not normally a problem, but any heat venting directly from a lone shed in a garden and the shed shows no heat signature (due to insulation) would be of interest to the skycops.I wish you the best and please share your results with us after you have put in place all anti flir measure and have done a flir test, the information would be helpful to others doing the same.I wish you luck and hope you are able to resolve all these issues.PeaceLams 3 Link to comment Share on other sites More sharing options...
