I have searched a bunch for any info on this idea. I am considering a small grow op underneath my house but I am concerned with a few things. First, the last thing I want is my house to burn down. Second, I'm not sure how to get a standard electrical outlet under there without a cord trail. Obviously, stealth is very important. Third, it's winter. I think the temperature will even out because of the lights, but I dont know. I was thinking about using a rubbermaid grow box to help trap warmth. My local weather has been fluctuating quite a bit, ranging from 32 to 55 degrees F a day, so I dont know if ill be able to maintain the temp. I was thinking about using fluoros the whole time because of my first concern. I can deal with a lesser yield if it means my house doesnt burn down. But then there is much less heat to handle my third concern.
