Some time ago decided to try #3DPrinting for #Food (not 3D printed food!) - with this sprouting lid for a mason jar (and stand).
Been a while since I mung beans sprouted so tried it this way now. Quite convenient, filling and emptying the jars and kept in stand draining under a box to keep light out. I let it go a bit too long at 6 days, should have stopped at 3 or 4 and perhaps less in the jar.
