Bottle garden
A bottle garden is a type of closed
illuminated.[1] The oldest bottle garden in existence is alleged to have been planted in 1960, and to have remained sealed from 1972 until at least 2013.[2]
Uses
Bottle gardens are commonly used as a form of decoration, or as a substitute garden in areas with little space, such as
dryland
areas and areas with a shortage of water, allowing water to be conserved for other uses.
Operation
A bottle garden has the essential requirements of soil, water, and light for the survival of plants and other organisms that are housed in it, as well as a reservoir of water, as water is trapped inside the bottle and unable to evaporate. The carbon dioxide in the trapped air is used for photosynthesis, and the oxygen produced from photosynthesis is used for respiration and expelled.[1] Aerobic organisms like shrimp, snails, or bacteria take this excess oxygen for their own respiration, and return carbon dioxide to the air. As such they require almost no maintenance.
