They use heat seeking equipment to scan rooftops for attick grow rooms of extra large amounts of heat loss .
Like say i,m guessing a bit so i would say they would be looking for 6 or more 1000 watt lights.
Much less than that could be from a poorly insulated attick.

QUOTE]Yes, the National Guard usually assists the State Police of each state (in the US anyhow) and the DEA has task-teams as well to search and erradicate all marijuana, mmmkay.
