Micro grow design, need YOUR opinion!

[Dion]

I also have a good design for a pc fan carbon filter I have been using for awhile. It uses two pc fans in tandem to create more pressure to push through the carbon allowing you to use a thicker layer. It is just a plastic container with fans mounted to the top and bottom and it pushes through the layer of carbon supported on expanded aluminum (gutter guard from home depot) and some fabric to keep it from falling into the fan. You can make the carbon layer as thick as you would like and change it as often as needed.
