Someone I know wants to start their own personal grow room in their closet. They're really not sure if they want to use a 150w or a 250w HPS for flowering. He/she is currently renting a place where the utilities are included, and the landlord deals with the power bill. There are three other people living with him/her, and they were wondering if a 250w HPS would draw too much power or if the landlord wouldn't notice at all.
