nOVEL COOLING IDEAS

I HAVE A 6OO WATT DIGITAL HPS IN A 3 X 3 X 8.5 CLOSET. tHE LIGHT IS AIR COOLED TUBE WITH A 465 CFM FAN BLOWING THROUGH THE COOL TUBE. THERE ARE NO VENTS IN MY CLOSET TO TAP INTO THE CENTRAL AIR BEYOND JUST OPENING THE CLOOSET DOOR. mY SET UP GOES 6 INCH CARBON TO A 465 CAN FAN TO COOL TUBE OUT OF THE ROOM. hOW CAN I GET THE TEMPS DOWN MORE. I AM RUNNING AT 90 F DURING THE DAY. MY GOAL IS TO BE AT 80-82 F. ALSO WOULD PUTTING A BIGGER FAN IN TO CIRCULATE AIR MAKE A DIFFERENCE. rIGHT NOW I ONLY HAVE A 8 INCH FAN FOR INSIDE AIR MOVEMENT

dOES ANYONE HAVE ANY IDEAS
THANKS

open the door when the lights are on, or make a vent (passive intake) that is connected to the outside room.

if you are in a bind you could get a small CFL bulb to maintain 12/12 and run your lights less like to 4 hour stretches in the 12hour window.

M-hold good idea i might try that. i have a 8 4 ft flo veg light. so u suggest 4hours on 1 hour off but during that hour using a cooler less lumen light option. My only fear is a weak harvest so obviously temps a very important. Thanks
peace
