  3. you'll need a fan ducting out of the grow. I have a 3x4.5 closet, and when the room's 60 that thing would hit 100f with the door closed.

    What do you think about exuasting from an air cooled reflector on the side with the bulb nd other side open for air in the tent


    Arrows are air passing

    Outside tent<<<<===<<<<<(fan)<<<<==(light)<<

    Would this cool the light enough?
     

  5. yes, as long as the room the tent is in can stay cool that way

    you may need to exhaust out a window if the room temp climbs, making the tent climb, etc
     
  6. If the exhaust dose not leave the room that your tent is in it will continually draw in the same hot air and bake your plants

    Now if you have AC on in the room and exhaust out of the room it will draw in the cold air from the room and cycle it out of the window or how ever you wish
