Mini Stainless Steel Hygrometer – Terrarium Humidity Meter

KEEP AN EYE ON YOUR LITTLE MOSS WORLD 🌿

This miniature stainless steel hygrometer is a simple way to keep an eye on humidity inside terrariums and mossariums.

At just 28mm across, it’s small enough to sit discreetly amongst the moss without taking over the landscape — particularly useful in closed terrariums where humidity levels can build up.

WHY MONITOR HUMIDITY? 💧

Moss enjoys a humid environment, but a terrarium that stays excessively wet can encourage mould and condensation.

A small hygrometer gives you a quick indication of the conditions inside your terrarium and can help you decide when it might benefit from a little ventilation.

HOW TO USE IT 🪴

Simply position the hygrometer inside your terrarium where the dial can be easily seen.

Avoid burying it in the substrate or placing it directly against very wet moss. It is designed to monitor the humidity of the air inside your terrarium rather than moisture in the soil.

PACKED BY THE MOSS FAIRY 🌿

Each hygrometer is carefully packed in Bristol by The Moss Fairy.

Perfect as a useful little addition to a terrarium kit, mossarium or existing miniature garden.
