Corm Cosy Self-Watering Propagator for Alocasia Corms

Corm Cosy Mini Greenhouse for Corms, Pups & Propagation | Designed & Made in Cornwall

The Corm Cosy is a 3D printed mini greenhouse designed for propagating corms, plant pups, and small humidity-loving plant material in a controlled indoor environment.

Designed for high-humidity growing conditions, it features a sealed lower reservoir area to hold water while reducing light exposure to help minimise algae growth. The system is built to maintain stable moisture levels for propagation and early-stage plant development.

The Corm Cosy includes 9 mini net baskets for individual corms or plant material, allowing organised and separated growth within a single controlled environment. The lid includes an adjustable ventilation system to regulate humidity levels depending on growth stage and plant needs.

Under optimal conditions, the internal environment can reach high humidity levels suitable for tropical propagation. The lid also includes space for an optional puck-style grow light (not supplied), and a cable routing channel for setup flexibility.

A hygrometer is included to monitor internal temperature and humidity conditions, supporting consistent environmental control during propagation cycles.

The Corm Cosy is designed and manufactured exclusively by us in Cornwall, UK, and is printed to order using our own original design. Due to the nature of the design, we only offer the Corm Cosy in our 4 'sparkle' filaments, as this produces a much better finish.
