I am wondering how safe it would be to run a 400 watt hps setup without a grounded outlet. I wanted to use the light in my closet as my electrical fixture by using a plug adapter. Is this a terrible idea? Because I would like to not have any wires running into my closet. My buddy said he ran his 600 watt hps without one but, I don't think of him as the smartest guy in the world.
