94 is way to high..blowing heat into the wall of your room isn't gonna help it just heats the wall of the room ..it has to come in from another room or better,outside..and go out into another room,attic or outside..if your heating your house kill the heat for your grow room..the light alone will heat a room that size..probably to 70/75 deg..is the ballast magnetic or electronic??..i use a two small personal desk fans to keep them both kool..move anything that generates heat out of the grow room unless it has to be there..
