Thinking of constructing a room inside of a room for my new grow. 5x5x7 2 600 watt hps air cooled hoods i will have an exaust fan blowing all the hot air thru a diy duct system im running out of my window. The question is i only have one window in the room and need an intake port frm outside. Will i be able to both intake new air anr vent old air thru this same window? What other options do i have?. Any help is appreciated ..cheers
