I finally solved my problem. This is what I did. Since i couldn't vent outside the room i was growing in, i created a smaller room for flowerin. The box i made has the grow space of 3 feet 6 inches height 20 inches deep and 28 inches wide. I created a hole for exhaust and now it even cools the box from the hot 400w bulb. Now my problem is heat issues since i still can't vent out of the room. So i solved that problem by duct taping three vents in my place to force air to flow faster to the room they are in. I then attached some extra ducting to the existing vent and made it so the A/C is flowin straight into the box. Hopefully this will take care of the heat issue while the exhaust fan is not on. Will post to fill you all in. I know you all are waiting with such anticipation....... HAPPY GROWIN!!!!!!!!!!!!!1
