Making a glass house for plants is an easy project for kids and families. Household items such as spaghetti sauce and juice jars make this project affordable and accessible at any time of the year. African violets and ferns do particularly well in terrariums and will sprout from seeds. Many types of culinary herbs will grow well in a glass house as well but may need to be replanted as they grow.
Use warm, soapy water to clean glass jar and lid. Remove the label to allow as much light in as possible and fully dry.
Lay the jar on its side with the lid removed.
Fill jar 1/3 of the way full with potting soil. Be careful not to tightly pack dirt as soil should be loose and airy.
Plant seeds or seedlings in dirt. Push roots or seeds half way into the soil and fully cover with dirt.
Use a spray bottle to fully mist plants and dirt.
Screw the lid onto the jar and place in a sunny location. Monitor seedlings as they grow and add water as needed. Soil should stay moist but not soggy.
