Transform large glass bottles or jars into charming mini-greenhouses, ideal for nurturing small plants, cuttings, or seedlings. These enclosed containers create a natural condensation cycle, recycling moisture and maintaining humidity with minimal care. Choose a closed system for high-humidity loving plants or an open system for species that prefer more airflow.

Decorative options abound—from vintage demijohns to modern glass canisters—making these bottle greenhouses both functional and stylish. Although similar to traditional terrariums, their simple construction and maintenance set them apart. For inspiration, visit Chicago Botanic Garden’s terrarium guide.
