I'm not going to go into a lot of detail about the electrical wiring. Either you know how to wire or you don't and if you don't then you have no business messing around with the electrical work. So if you don't know anything about electrical stuff, get an electrician to help you.

For the electric supply for this cabinet I tapped into my panel and installed 2- 20 amp circuits. I happened to have a Square D slimline 20 and some 12/3 Romex so I put in two circuits. One 15 - 20 amp would have been more than enough.

The electrical boxes inside the cabinet - the box on the right has four receptacles, all of which are hoo9ked to the timer. The box on the left has 3 receptacles that are always hot and one rec that is hooked to the timer but thru a rheostat to control the fan speed.

Outside I have the timer, rheostat and live receptacles. The orange power cord is for the ballasts. I also have a thermostat and hygrometer with remote probes that I'll mount in this general area.
