Soil dilemma, will I be okay?

I had good seeds germinate in a paper towel today and I was completely broke. I have a grow setup, but the only soil I could obtain for free was miracle grow potting mix -- I also obtained a bag of peat moss.

I mixed the two together in about 60MG/40PM ratio.

I do not want to try to grow in miracle grow soil, and I will be able to go buy some fox farm in 4 days. Will I be okay transplanting the sprouts after they come up in MG to foxfarm? (I'm aware of the nutes in MG, and I want to get the little things out of that as quickly as possible).

ew. get a four dollar bag of transplant soil and throw it in the bottom of a 2 or 3 litre bottle.

wait, i don't quite understand.. your saying to try and transplant just the taproot?
