How it works
Checked against real jars
Fourteen jars their owners described online, rebuilt and run: all fourteen turn out the way the real ones did.
- A 9-year carboy left alone: alive at 3 years, the tradescantia the biggest plant.
- Succulents sealed under a 9 h lamp: rot within weeks.
- A jar with far too much water: fog all day and rot losses within weeks.
- A new jar moulds in its first weeks and clears, sooner with springtails.
- A sealed jar in direct sun cooks within days; an open jar left unwatered dries out.
- Isopods in a 4.5 L box crash within weeks; a bog kept wet thrives at 6 months.
- Each case is built and watered the way its owner described, then judged on what they reported.
