CormPod - Self-Watering Corm Propagation Insert

Self-Watering Corm Cup Insert 🌿

A printed insert designed to transform standard lidded dessert cups into a self-watering corm propagation system.

Commonly used by the plant community as humidity domes, dessert cups are ideal for corm propagation — this insert enhances that setup by introducing a simple and effective self-watering solution.

Removable Base Design

The inner cup features a removable base, allowing you to:

• Gently push plants upward when ready to transplant
• Reduce root disturbance
• Easily remove established corms without damage

This makes transitioning to the next growth stage easier and safer for delicate roots.

How It Works

The insert sits neatly inside a standard dessert cup, creating a raised inner pot while leaving space below for a water reservoir.

A wicking cord can be added to draw water up into the growing medium, helping maintain consistent moisture levels.

• The overhang lip keeps the insert securely positioned at the top of the cup
• The lower section acts as a water reservoir
• Compatible with standard lids for full humidity dome setups
