Summary

This is my soil free microgreens sprouter. It has a 3D printable substrate, that flexes to allow roots to penetrate. Sit this in a tray to grow a small crop of microgreens.

Sit seeds in water for 24hours to soak, put a little water in tray, sit sprouter in tray and spray daily until the roots hit the water in the tray.

This was designed to fit in a mini propagator, the likes you find at wilko or B&Q here in the UK.

Grows a decent crop in two weeks.
