ventilation is important weather it comes from a cracked door or system. then you need to think about the light that may or may not come in from the windows for dark period. in a room of its own and some fresh air and fans a 400w isnt very hot. i dont know about the electrical costs of a 400w but a 150w and a fan was about 5$ so basicly triple that for a 400.
