There are many types of pre-mixed potting soil for you to choose from; just make sure you select a blend specifically appropriate for seeds, larger indoor plant, or outdoor plants, as they will each have different characteristics.
Small seedlings can dry out quickly and die, so they need growing media that can hold adequate moisture, but they are also susceptible to many soil-borne fungal diseases brought on by excess moisture. Make sure your potting soil isn't too heavy, and drains well, for all of your indoor garden plants. Coir is an excellent addition to help balance moisture and drainage.
