I came across a story on about David Latimer, who put spiderwort plants into a bottle garden ("terrarium") in 1960, watered it in 1972, and then sealed the bung. The plants have been living, thriving even, in their own ecosystem since.
The story was reported in the Daily Mail.
Thriving since 1960, my garden in a bottle: Seedling sealed in its own ecosystem and watered just once in 53 years
David Latimer first planted his bottle garden in 1960 and last watered it in 1972 before tightly sealing it shut 'as an experiment'
The hardy spiderworts plant inside has grown to fill the 10-gallon container by surviving entirely on recycled air, nutrients and water
Here it is again in The Times. There are a few more places this article can be found in various forms on the web.
Now this question text is copied from this Skeptics question. The reason I am asking here is that I have seen the exact same story and have the exact same question but, somewhat shockingly, noone on Skeptics thought to ask a botanist or even a biologist if any of that is remotely true.
Now, I am no botanist or gardener or biologist but I know the Law of Concervation of Energy. Which states that the amount of energy/matter at the start WILL be equal to the amount at the end if you consider all factors. Meaning if plants consume water and nutrients there is no way they can extrude the same amount they have consumed in order to consume it again.
Am I right in my thesis? Is this story possible?
