Cannabis growers' cover melts away
Clever PSNI officers have been using the recent snowy, frosty weather as a means of spotting cannabis factories in local houses.
A tell-tale sign, they point out, could be a roof where snow melts while all around stays frosty and white. The plants need heat so the cannabis producers have to keep their place toasty.
Then again, a defrosting roof could also just be caused by poor insulation. And criminals, I suppose, could also fake a snowy roof with those spray cans you get in the craft aisles. That said, good try, PSNI. I doubt the cannabis cultivators are now dreaming of a white Christmas...
