Why you should not fully empty the GEME Composter chamber every time
TL;DR Q&A block
Should I fully empty GEME every time I harvest?
No. The Terra 2 manual explicitly says "Do not empty the bin completely", because the remaining compost contains the microbial colony needed for the next batch.
Why leave some compost behind?
Because the remaining base is not just leftover material. It functions as a living starter bed that helps carry the biological process forward. Public hard-parameter guidance also says it is recommended to keep part of the base for continuity.
Does keeping a base mean the machine is dirty?
No. In GEME, “clean” does not mean stripping the chamber back to zero every time. It means removing what should be removed, keeping the system healthy, and protecting the living base that keeps the process stable.
When should I harvest?
Official guidance says to harvest when the mixing paddles are fully covered and no longer visible, or when the compost has accumulated enough that the shaft or paddles are buried.
Do Terra 2 and GEME Pro follow the same logic?
Yes. The biological logic is the same for both. The main difference is the operating envelope: Terra 2 is positioned at 2 kg/day with a typical maintenance suggestion of 3–6 months, while GEME Pro is 5 kg/day with a public maintenance positioning of 6–12 months.
