Seeding Soil!? NEED ANSWER ASAP

So I got my seed today, started to germinate it, went to go get my soil and I cant get it til next friday. So I need a good seeding soil to last me for like a week, then do a transplant, anyone know a good seed soil that will last me just a week or so?

anything without nutes

miracle grow from home depot, get organic stuff

Any soilless seed starting medium will do... I use Jiffy Organic Seed Starter... 100% so far... keep it moist.
