Tips:1. The weather is too hot. Soybeans have grown sprouts in two days. It is best not to exceed three days, otherwise they will easily break.
2. Do not see the light when the bean sprouts are sprouts, otherwise the mung bean sprouts will turn red and have a bit bitter taste; the soybean sprouts will turn green, but the taste is the same.
