When you vent the heat what are you doing with the air?
A/C is in adjacent room where the intake drawers from. The A/C heat exhausts outdoors through a window(A/C in Summer looks normal enough). The Ballast are in the room for reasons of concealment, but generate very little heat relative to the lights. Vented heat goes into a closet(veg room) which has a smaller exhaust system of its own(aswell as doors open). From the closet it enter a living room on an open floor plan with the kitchen(A/C intake room) in which the warm air is recycled into cold air.

Scenario

I flex-Tube my intake through the three lights with the aid of several 80cfm in-line fans and have them run constant regardless of exhaust being on or off. Rather than having the lights exhaust outside the room, the flex-tube empties several feet from the carbon exhaust filter within the room. When exhaust activates, it should still effectively exchange the room's air and the velocity at which the cool air travels through the lights will be increased. Will this create cooler conditions, or ultimately will room temp be the same by the time the air exits the 3rd light? I think funneling the cool air directly through the limited sq area of the lights is better than a general purpose in-take for the over-all room.

Thanx for your feedback
