This is what our sprouter looks like. It’s a plastic vessel that holds water, an insert (shown upside down) for draining and a lid. We ordered it online, not sure where from, but my husband thinks it cost about $8.
We had one of the three tier sprouters before this one. The nice thing about those is that you can sprout multiple seeds, that take different lengths of time to sprout, all at the same time. The downside, though, is that we found the trays weren’t tall enough for some of the seeds and the sprouts would get squashed, or it would stunt their growth.
