From personal experience, the easiest way to sprout an avocado pit is to throw it in some moist dirt and put clear plastic over it to keep the moisture in.

They take about 30 to 45 days to sprout. And the success rate it about 75%. (though I've never been scientific about it, so my numbers may be off)

My setup is two 8qt plastic storage containers. One for dirt, and one to trap the moisture.
