Yes, do install intake and exhaust vents, a/c units typically don't draw outside air (they just recycle it); your plants need fresh air, whether it comes from the out-of-doors, or outside the box; they need plenty of it! How big is your space? that's the only determining factor in my mind.
4x5 Reviewed by 4x5 on . Vent in and out question I just built a new flower room. I didn't put in any intake or exhaust vents,,, because I have a 5000 btu air conditioner installed. Will this replace enough air, or should I still install vents?. I don't want the vents to undermine the work of the A/C. Think this might be a prob?? Thnx P.S. Look!!!!!! My caps lock button is fixed!!!! Hurray!!!! Rating: 5
