Why clean

A kit put away dirty carries the spores of damping-off fungi — the disease that makes seedlings collapse at the collar. The finding is clear: a large share of sowing problems disappears when containers are sterilised. Cleaning is not a comfort — it is sanitary prevention.

When to clean

• After every use — before storage, systematically.
• Between seasons — before recommissioning in spring.
• After any mould or damping-off episode — disinfection becomes mandatory.
• On receiving a second-hand kit or one stored a long time.

The cleaning protocol

• 1. Empty — throw the used substrate into compost or green waste (no reuse).
• 2. Disassemble the kit — each part cleans separately.
• 3. Wash in hot soapy water — brush the corners and drainage holes where substrate lodges.
• 4. Rinse thoroughly with clean water.
• 5. Disinfect if needed (next step) — recommended between seasons.
• 6. Dry completely in the air — critical: residual moisture favours mould in storage.

Bleach disinfection

The proven method for reused containers:

• 10% bleach solution — soak the parts or wipe them soaked.
• Air drying afterwards — contact suffices, no hard scrubbing needed.
• This disinfection eliminates the residual fungi behind damping-off — soak reused pots and trays in a 10% bleach solution and let air-dry.
• Rinse afterwards and dry completely before filling.

Drying and storage

• Complete air drying — the most-skipped step; a kit stored damp comes out mouldy.
• Dry, away from prolonged sun — UV weakens plastic over time.
• Stacked cleanly — Germie kit cells organise for compact storage.
• With the 10-year warranty, a well-kept kit outlasts the warranty — cleaning is the investment that pays.

Frequently asked questions

How do I clean a germination kit?

Disassemble → wash in hot soapy water → rinse → 10% bleach disinfection if needed → complete air drying.

Must I disinfect every time?

Recommended between seasons and mandatory after any damping-off episode — otherwise a good wash suffices.

Can the substrate be reused?

No — throw it away: it potentially carries pathogens. The kit washes, the substrate is replaced.

The Germie kits disassemble completely — the thorough cleaning that keeps a kit alive 10 years.
