It depends on your insulation and where your grow is mate.Hey, can anybody tell me if the heat from 400W HPS bulbs can be seen by a police helicopter's infrared camera?
Thanks
Bro, you live in 209 area code in Cali? If so, what up, I used to be 209, now 559, represent! lol.yeah several 1000 would be seen infared but a 400 would show real light wouldnt be investigated over that look more like a flood lamp or some shop lights
Like everyone else has said a singlee 400W light isnt much, especially if your venting the lights heat outside the growroom. if you're that worried about infared try this stuff out http://www.discount-hydro.com/productdisp.php?pid=552&navid=33Bro, you live in 209 area code in Cali?

OP: Too much paranoia will get you busted, and not enough will too. Find a happy medium. And no, a 400 w light isn't gonna raise any eyebrows.
