Hemp mat / Square humidification mattress

Designed and manufactured in France, this hemp mat or high-density humidification pad (1000 g/m², thickness 5–6 mm) is specially created to retain moisture in the top tray of your worm composter, where the worms are most active. It is placed directly on the worms in the active tray (top tray), optimising their comfort and activity.

Benefits & use:

• Maintains moisture: keeps the top layer moist so the worms stay active and efficient.
• Encourages worm movement: allows the worms to come to the surface to feed and digest waste faster.
• Protection from cold and temperature changes: ensures a stable environment for your worms and waste.
• Limits insect development: reduces the proliferation of fruit flies and other pests.
• Eco-friendly & degradable: 100% natural, the mat decomposes over time and can be consumed by worms.
• Handy tip: lightly moisten the mat with WORMboost diluted in water to stimulate worm activity.

The 33 x 33 cm square format is compatible with the following worm composters: TinyWorm, WORMcube, Lombribox, City-Worms.

The hemp mat is the essential accessory for maintaining an efficient worm composter, protecting your worms, improving compost quality and limiting pests — all while staying natural and eco-friendly.
