Does anyone know if there’s a big difference in static pressure between insulated flexible duct and say the standard rigid duct available at home improvement stores? Perhaps @Countryboyjvd1971 you can school me here.
I’m asking because I see a stealth grow box in my future. There’s some nice half inch birch plywood that’s going to be leftover from a cabinet I’ll be making. Not a lot, but enough to do maybe a 16”x20”x48” box.
My vision here is to install the fan in bottom of cabinet underneath a false floor that will also have a passive intake and light trap built into it. I found a long narrow carbon filter that I plan on installing vertically in a corner, and then ducting to the fan below the floor. I’m not sure if I’m gonna just exhaust out the bottom of box, or run duct back up and exhaust out the top. So thoughts here are welcome too.
