The room is 4"x4"x6".....I can drop a flex hose from the top...where the bathroom exaust fan is installed..(wondering if this batroom exhaust fan would push air down the hose?). This air would then be dispersed from the bottom..........also the entry way to the grow room is a door made from black plastic velcrowed to a wooden makeshift door frame. So I could crack an opening for some air to get into the room by undoing some velcro, anywhere along the door frame, bootom, top, or sides.....Some light could escape though.
It might be simplest for me to use the grobrit inline 4" inline fan with carbon filter. Thinking this would expel the stale air and odor out the chimney stack.
But I will check out the 6" vortex that can be hooked up to the light bringing in fresh air, cooling the light, and then emitting stale air and odor. But i don't understand how this works completly. I understand theres probaly a fan pushing air down a flex hose into the light cooling the bulb. Then the next flex hose leaving the light must have another fan drawing heat and odors out of the room. (probly with no carbon filter). Where am I confused?
