When you are eating more sprouts than you can grow in quart glass jars, it may be time to invest in a larger sprouter for your seeds. You could purchase a commercial-type sprouter from the health food store or you could save a tidy sum by building one yourself from items purchased at the local hardware store.
Cut the 1-by-1-inch lumber board into two 8-inch-long pieces, two 9-inch-long pieces, two 11-inch-long pieces and two 12-inch-long pieces.
Lay the two 9-inch pieces on your work surface and insert the two 8-inch pieces flush on the inside of the 9-inch pieces to make a square. Secure the corners with two brad nails on each corner.
Repeat the same process with the 11- and 12-inch pieces of wood.
Cut one piece of aluminum screen to 12 inches square. Cut a second piece to 14 inches square.
Secure the screens to the wooden squares using a staple gun and staples.
Place the smaller square, screen side down, and lay the larger square, with the screen side facing up, over the smaller square to finish the sprouter. In this way, both flat sides of the box are now screened, making rinsing the sprouts easy under running water.
