When starting seeds indoors, some kind of container needs to be used and there are many materials available. Plastic pots have often been a choice but there is a trend, especially among many gardeners, to try to be less dependent on plastic. Consider Cow Pots for your seedling this year. Made from composted cow manure, they can be planted directly into the soil. They are odorless, non-toxic and promote recycling agricultural waste. And another benefit is they provide nutrients for your plants.
