I've had success earlier with this year by using some good soil, combined with peat. The seeds I've messed with are green belle pepper seeds and red belle pepper seeds from the ones out of peppers at the grocery store.
I have about twenty belle pepper seeds outside now. Some are placed in the soil (ie, sand outside) and some others are in some composted soil. The ones in the composted soil are a couple feet tall now and the ones in the sand are struggling to grow. So that's telling me that a good rich soil helps, esp. a soil that holds moisture.
Also, the heat outside causes them to sprout within a week hear in Florida. The ones in the pots are 18" high now and the ones in the sand are 2" high, so you can get a good idea in the comparison.
Furthermore, I had one in a very small pot with composted soil. It outgrew the pot pretty quick and last week I moved it to a sandy soil area and it's starting to sprout pretty good and is about 18" high like the other peppers in bigger pots. So you can start them out in very small pots with nicely composted soil and then move them to another unenriched area after they reach 8" to 9" and they seem like they'll take but the peppers will take longer to come about.
Also, I've had to move all my potted peppers to shaded areas. They don't seem to handle 90 degree temps too well in full sun.
Hope that helps.
