Well I am happy with my plant shelf but I want to make it cooler, once I put some insulation on it, it should hold in cool air better than just the panda film I have on it now. But I also want a stronger fan, but not a much bigger fan. 4-6" diameter is as big as I want to go and it needs to be flat and mountable like the PC fan from radioshack I currently use which is mounted on my windowframe. I just crack the window (or even not open the window in mid winter) and the cold air gets sucked into the air vent. It's just not powerful enough to drop all 3 shelves as steep as I want during the lights-on period mainly. It worked fine in the old days when i was cooling only one shelf. If I can bring in 2-3 times more flow I'm relatively certain all 3 will be right where I want them.
So, does anyone know of small square fans or mini box fans I could use other than a radioshack PC fan?
I bought a housing ventilation "booster fan" from the hardware store and wired it up but that thing makes it sound like a plane is continually flying over the house so I'm not thrilled with that at all.
I'm looking at this:
and wondering can I wire it to a power cord or maybe even a lighting dimmer switch to adjust the speed, and will it be crazy loud being an air-conditioner fan?
