Microgreen Growing Tray for Pea Shoots

I designed a convenient tray for growing microgreens. This version is optimized for pea shoots (large seeds), but you can place a non-woven fabric at the bottom if you want to grow microgreens with smaller seeds. A water-level inspection hole is included for easy monitoring.

The set includes:

• Tray
• Seed grid
• Germination lid

Recommended printing:
Print the tray with PETG for waterproof properties.
Print the grid without bottom or top, using 10–20% honeycomb infill, depending on your preferred hole size.
It's best to print the lid in black (or another dark filament) to block light during sprouting.

Growing process:

1. Soak pea seeds in water for 6–12 hours.
2. Spread the soaked peas in the seed grid in a single layer. Pour water into the tray so it doesn't touch the grid. Cover with the lid.
3. Wait a few days until the stems start to grow and the lid begins to lift. Once a day open the lid, spray the seeds with water, and make sure there's always water in the tray.
4. Remove the lid to expose your microgreens to sunlight.
5. When the microgreens reach the desired size, cut and add them to your favorite dishes.
6. After harvesting, cut the roots from below, wash the tray, and repeat the process.
