Utility companies can tell your bill is way off from the same time last year, and police are finding growers this way. More than 500 watts in the family home running constantly will show up as a regular monthly increase in electricity use. You can claim space heaters, more people living on the premises, too many television sets, and late hours, if they happen mention it to you (innocently). If the police knock and ask you about it, don't let them in, and move your plants to another location during the wee hours in a vehicle not your own.

Upon moving into a new place, it may be desirable to immediately establish high electricity use, so that your electrical use history won't reveal your activities in the future...

Light leaks, open windows, heat expelled from rooms that would normally be cool, and rip-offs are all serious issues to be concerned about. Don't use a burglar alarm on when your away from the house. People are busted this way when the kids try to rip off the garden and the police come. Lock the house up well, and let them take it if they need it so bad. It's not worth getting busted for a burglary...

Think ahead to any situation that will require outsiders to visit sensitive areas of the house. Repairmen, solicitors, meter readers, neighbors, appraisers, and pets should all be considered and contingency plans made in advance.
