Proper starting soil?

[MasterChief420]

IS this a good soil for me to begin growing my plants in.

it says

"Fine textured mix contains nearly equal parts sphagnum peat moss and vermiculite with limestone, gypsum, and a wetting agent. University tested for maximum germination. Ideal for rooting cuttings and starting seeds of all kinds. "

I have some similar potting soil that's specifically for starting plants, as well. It says on the bag that it shouldn't be used as a potting medium beyond sprouting. It contains higher levels of potassium to stimulate root formation, but beyond that, you should plan on a mix of different materials (see various guides) as a growing medium to transplant them into afterward.
