Actually, when it snows, you can guess fairly accurately which houses are hosting an illegal grow op by looking at the roofs. It takes a LOT of wattage to melt all the snow off the roofs in the middle of winter. Try this "trick" some time this winter.

They too are trying new technology and switching to LED as well.

HAHAHAHA....+1 to that!

My wife came home one day with a package all neatly wrapped up in CBSA tape. She was wondering wth I was upto now. Turns out it was a 1kg bag of enzymes for my brewing hobby, coincidentally a nice fine white powder, lol.

I have a friend in cow town that is into growing orchids. He keeps a greenhouse inside in the winter with a few dozen plants heaters lights etc. He didn't realize it was visible to the neighbors until one night when the door came off the hinges and he had a gun pointed at him....few embarrassed officers that night!
