Tell me more about your 2X4' area. What wattage lights here & about your cooling. My camper grow closet is about 2 1/2'X8'. Since I'm using 4' fluorscents, using 1/2 to put my veg fish tank in. Can't throw a lot of wattage in there because I'm running extention cords. Had an electrical fire last fall during hurricane because of over loaded cords, made me paranoid. Fear of another fire is seriously limiting my possibilities, but I can visualize your space & dream untill my outdoor grow next year. (Sm perpetual harvests are better than nothing). BTW, Este still MIA....worried.~~~PEACE~~~
