A Sink Colander for sprouting seeds is one of my favorite among aviary equipment. The side handles expand to fit your sink. Shown is ABBA Products soak seed which is covered with water for six hours and then placed in the sink colander for sprouting. Seed is sprayed in the colander daily. Works great!
I purchased mine a few years ago at Aldi. Aldi is a German company offering groceries and a few extras in the US. Today's ad featured the sink colander!
