How to grow soybean sprouts at home? How to grow thick soybean sprouts? How long does it take to grow soybean sprouts? Learn everything here. First step in growing your own soybean sprouts is to use soybeans that can be sprouted. There are several varieties of soybean; some germinate well and some are not. If your beans do not sprout, try another supplier or variety. The simplest method for growing bean sprouts at home is to use a bean sprout machine. The bean sprout machine will automatically spray water on the beans keeping your beans moist. It takes 3 days (approximately 48 hours) to sprout soybeans to 1 inch and 4 days (approximately 72 hours) to sprout soybeans to 2.5 inches. Cooler temperatures will slow the growing process, and warmer climates can speed it up. Another point to note, soybean sprouts must be grown in the dark to prevent changing in color. Set the bean sprout machine in a dark place while sprouting. You will likely never get your home grown sprouts to look like those you see at a restaurant or supermarket, but you can still get some thickness by placing pebbles on the beans. Pebbles are used as weights. The sprouts become thicker if the beans are grown under a weight that exerts pressure on them.
