My sprout growing device resembles a tiny greenhouse with a mesh screen at the bottom. I got it from Tony Hornick. You can sprout in mason jars with screen, but I like how sprouts can be grown to have leafy green tops using this system.
I have mung and adzuki beans, and green lentils to sprout.
Below is a photo-documentation of the sprouting of mung beans over the course of about 7 days.
