Well, I hope everyone reading this thread takes a moment to check out their breaker box and review their electrical situation in general. Before you grow anything, know exactly which circuits match up to which receptacles and know how many amps that circuit is rated for. Calculate how many amps your electric gear uses for each circuit. Take into account the "start up" amps of things like window air conditioners, in addition to the average amps they use. Device amperage adds up FAST, especially when you set up a typical grow tent. Consider spreading your grow equipment across multiple circuits, and don't max out a circuit. You should ideally only use 80% of a circuit's capacity, so no more than 1200 watts on a 15 amp circuit. ALSO, everyone should get a little $5 "receptacle checker" and just plug it into all of the receptacles in your house to make sure nothing is fundamentally wrong and to make sure that receptacle is grounded. You would be AMAZED at how many receptacles are wired wrong. I did this at my new place and discovered that 4 of my receptacles, all on the same circuit, are not grounded. Also, I highly recommend that everyone use either a gfci outlet, or a gfci power bar for their grow lights/fans etc, it's just another layer of protection.
