How to grow indoors in UK attic, bedroom or shed. Please help me

the heat coming out the tent n after the filter n fan could they not be read by the helicopters if you had it in your attic ? the heat coming out the roof pipes for the fire. don't the proper name?

tbh i think 1 400w, 600w Hps going in 1 house will be hard for cops to get warant to scarch ur place as they go with electric usage and the not the expenive to run realy £7-10 per week id say. bit safer growing in bebroom esp with cold in winter with temps. do the tent with lst,, wat size of tent can u do?? if u do 3x3 - 2 plants... 4x4 - 4 plants to get maximum yields more plants doesnt mean more yield..

anyway mate i started a thread on here with a grow still going now, i got be pissed of with not getting much responce il get back to it and show all how were finshing up.. cheak out my LST training 1st time iv done this was pretty easy just put holes in ur pots with a drill,, from maybe 3rd week in veg u topp ur plant and 7 days after that u will start to tie branches to the pot,, go easy on them.. they can be repared if u break a stem with band aid very easyly. ps dont grow in attic in uk over winter less u got lights off temperature controled.

am best of waiting then till winter finished then start
