For the fans, I used some common fans used in entertainment centers to keep ones X-Box and such cool. I bought a kit with two fans and one thermostat that I could program to come on and shut off at predetermined temperatures. The particular kit I used was simply a plug and play using a USB with no wiring required but I did find out the wires ran a little short thus some wires are seen inside of the box when my original plan was to run all wires on the outside.

Materials will depend on what size you want the box to be. In this case, the box was 33″ tall x 18.5″ wide x 18″ deep to house starter plants and those that will reach a max height of about 24″.
