I recommend printing these pods with PETG, because it does not degrade easily and will not leach chemicals into the water.

A precision grow pod designed to hold loose, soilless planting media such as sphagnum moss, perlite, or custom blends in hydroponic systems like AHopeGarden.

Unlike sponge inserts, the MicroMedia Pod supports real substrates and surface-sown seeds, making it ideal for carnivorous plants, light-germinated species, aquatic seedlings, and any grow style that depends on an open, breathable root zone.

Features:

Retention mesh tuned for loose organic or mineral media

Open base exposing the medium directly to the reservoir

Tall, ventilated body to reduce stagnation

Supports surface seeding (no burial)

Reusable, sterilizable, and media-agnostic

Built for growers who want full control over substrate behavior in hydroponic and semi-hydro environments.
