Folks.im at my wits end here ,after yesterdays scare. I was in my shed having a joint and could hear a chopper in the distance(not un-common btw)I went into the house and could see it about a half mile away from the window. The worry I have is that my grow room is a bedroom,with a growroom build with plasterboard in side.It measures 2 half feet wide,8 feet long and about 9 high. Im using 2 x 400 w hps lamps. The temp varies,depending on when the thermometer is. up above its quite cool,but hotter below lights. The outer wall,including cavity,is about 13 inches thick.The lights had been on for 10 hours by this time. Supposing the filth were using a heat camera,would it have shown up? Please reply as im panicking like hell here. my wife could lose her job too if shes roped in on this.Please help. Dai
