Corm&Seeds Self-Watering Cup with Humidity Dome

Also known as a self-watering propagation cup, this setup is designed specifically for growing Alocasia corms, seedlings, and young plants.

It makes propagation easy, consistent, and beginner-friendly, while reducing the risk of overwatering, drying out, or rot.

The 1.5 oz inner cup sits inside a 3 oz water reservoir. A wick pulls moisture up to the substrate, keeping it evenly moist without guesswork.

Clear snap-on dome helps maintain stable humidity during early growth, supporting faster sprouting and healthy roots.

Inner cup has drainage holes to prevent waterlogging while still allowing airflow to the roots.

Sized perfectly for Alocasia corms and small seedlings, making it easy to monitor moisture and growth.

1. Fill the outer reservoir with water

2. Add your preferred substrate to the inner cup

3. Place the corm or seed

4. Insert the inner cup so the wick sits in water

5. Snap on the dome

Remove the dome occasionally as the corm establishes for better airflow.

This is the same setup I use daily for propagating rare Alocasias. It eliminates the most common issues - drying out, overwatering, and unstable humidity - so you can focus on healthy growth instead of troubleshooting.

 

These photos show my personal Alocasia corms to demonstrate how clear and effective these pots are for root growth. You will receive the empty clear pots ready for your own soil and plants!
