Growing In The Loft In The UK

need some opinoins about growing in the loft???
heres wot i plan to do
board over the roof juists with plasterboard, then fix loft insulation to the board, then board over that then finish with black and white plastic for reflective so its like a sandwich, WAIT i here you say? why not insulate the roof joists then board over that??? the reason is to get cold air under the roof tiles, thus trying to creat a cold spot to stop the helicopters finding it. just gunna use 4 250w hps (they dont creat that much heat but i want to put a small oil filled radiator in to keep the space at around 65 degrese
also there will be 2 1x1x2 tents in there
i have all the materials already.
what do you think, WOULD THAT SORT OF SET UP BE EASY TO SPOT FROM THE AIR????

really hard to say.

i would try to insulate as best you can and exhaust the hot air from the tents back into your house to avoid heating up the attic.

thanks for the reply jondamon.
i was going to blow the heat back in to a unused room (filterd through a carbon filter of course) i would like to keep the room at a steady 75 degrese lights on and 68 lights off. even at 75 with all the insulation surly wouldnt pose to much of a heat issue for police to investigate??? now that winter is just about here surly all lofts will glow a little on the IR detection due to everyone putting heating one?
anymore advice is welcom

i am roofing loft conversion expert and i disagree with you plans.

you should buy some kingspan tp10 100m and cut it to fit between the roof spars. if you want to go all out, do this then over the top of that put some tri-iso super 10. it is a blanket and you just tack it straight on to the spars. expensive but will stop you roof glowing white to a chopper. you won't need plaster board then, you will need an exhaust however as there will be a lot of heat/moisture build up.

ventin in to a room in the house is a good idea, free heating lol

i did the same with kingspan in an out house, looked out yesterday after a freezing night and the roof was covered in ice - happy days kingspan rocks

tri iso super 10 is better,its thin(abou 20mm) no cutting and slotting in, just roll it over the joists and tack as you got, also its reflective and i think i'm right in saying it out perfoms pretty much anything else.

i strongly reccommend it

thanks GHB
so what price am i looking at per roll??

just had a look online but can only find it in sheet/block form.

b&q also have a thermal roll made of foil covered bubble wraP with a foam lining - only 5mm thick but 95% uv proof - £18 a roll - used as well as kingspan for peace of mind

i get it for around £140 a roll with my trade account, you will prob pay more than that. look around on the net: ACTIS tri-iso super 10.
it is a 20 square metre roll and as i said you just roll it out on the inside of the spars and tack it as you go, so easy and because it is so thin it makes your room bigger. no need to put up plasterboard etc because it is wipe clean and reflective.

give it a go, you dont even need a tent but seeing as you already got them it will do no harm, you could stagger your flowering times or have two different strains with different flowering times as to be perpetual.

good luck with the growin

thanks for your help ghb, just gave you rep+
i will have a look and see wot i can come up with

let me know what you do, takes some pics an shit please or do a journal.

my friend is doing something similar,never really thought about heat lamps but he is only using one 250w in a budd box,insulation is awful and is freezing at night he has them 12/12 just now through the night do any of you guys think that will be warm enough to keep his girls ok during the day around 6c air temp or will that kill them at that tempreture he did well in the summer,only six weeks left of flowering i think surrounding the tents with king span would be good but no harm in being para bout the birds would the babies suffer in daytime tempretures when some days can be probably only 4 to 8 degrees c then the light should keep them warm at night ?answers on a postcard please...

I wouldnt worry about the choppers.
Ive been growing in my loft for years with 4x1000w and never once had a knock at the door. In fact i dont know of a single person that has been busted by a chooper

hi ze4
were you from country wise?? if your from the states the law as i understand in the states is they can't use choppers to detect grow ops anymore, something about your constitutal rights. so hows your loft set out you must have it WELL insulated??

i will be starting it this weekend hopefully? and i will take photos from start to finish, infact i will do a proper grow journel this time instead of my half finished ones lol. i will keep you updated and post links to it.
at the moment i am vegging 5 swiss cheese and 5 auto flowering called QUICK ONES by royal seeds. and 4 are in second week of flower, 2 in dwc and 2 in coco, the ones in the dwc's are powering along. and i thought coco was the best. but we will see one harvest day

i have a 450w electric radiator in my grow tent (2.4x1.2x1.2m) it is on a timer so when the lights go out the heater kicks in. it works a treat, if you were to add extra insulation on the grow cab i think it would be too hot lights on and too cold lights off.

i grow in a loft in the UK and i run 1x400w hps n 1x600w hps without loft insulation and it doesnt show at all on a thermal imaging system when you look at the house from out side

im sure the ones the police use are likely to be a lot more powerful.
i only say this for your protection, i saw a programme where the police said that they use the helicopters as one of the main tools for gathering info on potential "cannabis factories".
i also read in the paper that they acted on this intelligence alone to raid a womans house who wasn't even growing, she just had poor insulation. you would think they would need more evidence than just a warm roof, idiots.
