Corm Propagation Risers & 2 oz Cup Sets
Give corms a clean, elevated space to develop roots with these PETG propagation risers.
Choose between Risers Only for use with compatible 2 oz portion cups, or a Complete Set that includes clear 2 oz cups and matching lids.
The perforated riser elevates the corm above the bottom of the cup while allowing roots to grow through toward moisture below. This helps reduce prolonged contact with standing water while supporting water circulation around developing roots.
Ideal for Alocasia corms, aroids, bulbs, and other small propagation projects.

Riser Height: Approximately 10 mm

The riser is intentionally slightly smaller than the inside bottom of the cup for easier placement and removal.
Cup Compatibility
The risers have been test-fit with:
- Amazon Basics 2 oz portion cups
- Member's Mark / Sam's Club 2 oz portion cups
Cup dimensions can vary between brands and manufacturers. If purchasing Risers Only, compare the approximately 41 mm riser diameter with the inside bottom diameter of your cups before ordering.
