This niftly little sprouter is a great 3-tier sprouter option. You can grow a range of seeds and beans, including mucilaginous seeds. No fuss, no frills, this sprouter does what it says. The spacing between the trays allows for good airflow on each tray and the holes are big enough that the water filters down nicely. We recommend this sprouter for some of the larger seeds (mixed beans, peas, lentils etc.) as the smaller seeds can fall through the holes.
