Time to harvest. The most time consuming part is cutting away the roots from the sprouts.
I was hoping the roots penetrated the cloth would make cutting the root away easier, but it only save about 30% time while causing more wastage. This is due to the fact that the sprouts didn't grow in a compact and uniform way.
A tray of sprouts is probably only good for a single meal.
From the time of soaking the beans in water until harvest, it takes 4 full days.
