Paper egg cups make the perfect container for starting seeds and growing transplants.
Simply cut off the top half/the lid of the cartons, and fill each cup with potting soil. Place them on a sheet pan filled with water, and the set the pan in the sunshine or under grow lights. When the seedlings are ready for the garden, just cut the cartons into indiividual cups, and place the whole things in the soil. The cartons will dissolve, just like those biodegradable pots you can buy, and there's limited cleanup and effort.
