Good idea. If you are referring to peat pots, there are reams printed about how that is not ideal. I have used soilless mix for most of the time growing from seeds. An experiment a couple of years with the pots resulted in complete failure. Not good for starting and not good for growing and then transplanting into the garden.
For me, regular soilless mix does just fine...most years. I have used whatever was on sale at the end of the year and used it in the spring. This year it was Schultz and it is pretty coarse and doesn't hold moisture very long so special attention must be paid daily so it does not dry out. Starter mix is finer and should work OK.
For me, peppers need a little extra heat underneath and that will dry the soilless mix more often.
