interesting question,

i think your pretty safe with cfl's, but you have to assume your being watched in this day and age.
im in the UK, in a bungalow running a closet 400w hid vented into the attic, which i guess would look like a fireplace or boiler on infra red.

if your growing in the attic, then your roof is going to show up a bit brighter than your neighbours, so u have to think about insulation, which obviously you have done....line the sloping roof parts but also alow heat to escape.

i guess a heat exhaust would also look obvious unless it diffuses in some way.

in my opinion, its better to grow on the first floor and vent into the attic which will spread out the heat nicely, but with flouros, i wouldnt worry too much to honest.


i dont know how good it is, but i found this today, it "claims" to be infra-red-proof?

it might be worth doing a google image search for infra red images, to see what looks normal and what dosent...but like i said, i wouldnt worry with cfl;s, unless your running a lot, and your grow space (attic) is gonna show up warmer than the surrounding houses
babystarbud Reviewed by babystarbud on . Safety Issues + COPS + Helicopters in the UK! Im pretty scared to make my next grow using way more lights than on my last grow. Recently here in the south of UK, a gang of 15 growers where growing in a house they bought. They had a flowering room, veg room, cloning room, and they were growing outside in between tomatoe plants. They all were help in cuusterdy for several days till courte came, where they were put in prison in plymouth for 12 years.
