The wattage depends on how many plants you are going to be growing, and what type of setup you want.

For seedlings you could use 3 or 4 CFLs and put them a couple inches above your seedlings. The CFLs are nice because they will not sizzle your babies and won't dry out the soil as much.

To germinate your plants, just put the seeds between two moist paper towels and then put in a Tupperware container and then put it somewhere kinda warm, like on top of a refrigerator. Or you can just plant the seeds right in the soil...
