We will look at the lighting, the cooling system, a few safety features, timers, and the basic grow chamber (where the growing takes place).
If you already know how you want to set up your system, you may still get some good ideas from looking at mine. If you are a beginner there should be enough detail in the words and pictures to answer most of your questions. If you're like many you can just gloss over the pictures and get all you need.
With that out of the way lets get ready to make your house look like Sanford and Son.
Step 1: Making the light rack
The rack simply has no other purpose than to hang lights from. You can use a stick if you want to. It will do the same d#mn thing for you. But, I wanted to be crafty and thought an industrial looking truss shape would be way cooler.
For the rack you will need:
Little S hooks
Two 1"x2" wood sticks (I bought 2 eight footers for $1.40 at Home depot)
Two four foot 3/8" wooden dowels Lowes
Wood glue (I used cya glue slow setting) you can use any glue
3/32"" cable (vinyl coated or not) maybe 5 feet (Home Depot sells per foot)
1/16" aluminum crush ferrules (two doubles and two singles) Home depot has them
Four clothes line pulleys Harbor Freight
Small chain need aprox 30' depending on your ceiling Lowes
Expansion anchors Lowes
Rope cleats Harbor Freight (I found tiny ones from Home Depot)
Smoke detector 5$ at Home depot
Battery type drill
3/8" drill bit
3/16" drill bit
Phillips bit for the drill
Saw (circular or jigsaw)
