Hydroponic Puck

Hydroponic puck for supporting plants in an NFT or similar hydroponic system. These are designed to be laser cut in 3/8 inch EVA foam (commonly found as interlocking floor mat tiles). The design was created for use within a hole made by a 2" hole-saw, though they should work without the need for scaling in a hole made by a 50mm hole-saw.

Hydroponic_Puck_v1: Main part for use with mature plants.

Hydroponic_Puck_v1a: Designed for use with seedlings/cuttings in a propagator. Can also be used as a blank when large plants span more than one hole in an NFT rail (prevents algae growth).

Hydroponic_Puck_v1b: Designed for up to 5 very young seedlings to share a single space in a propagator.

This design was inspired by Hoocho's on YouTube:
