You understand what a glass hurrcane is? I can't just imagine how I would set it up into a picture but I can attemp with a keyboard.
They make various sizes of hurricanes some of them pretty fucking huge. They make em for candles in windy weather.
I would have a pc fan mounted to a standard vent. I would find a way to mount the hurricane over the fan so air is moving through the center of the hurricane. I would then place the lights inside the hurricane.
This would cause a negative pressure in the box causing passive airflow into the PC box. The real upside however is the air will move through the box, across the lighting, and directly out of the box after cooling the lights.
It would be a mini cooltube set up for a PC grow. Haven't seen that done before...
