It is the third day, where the bean sprouts are 5-6cm long. They are fresh and crunchy, and taste pretty good.
I decide to harvest them today, as I am worried the hot weather will make them thin and sauggy by the next day.
The quality of harvest from the tea pot, porcelain container and a custom made plastic container are almost the same.
There are many small beans didn't sprout to full size (less than 1cm) and I wonder if this is the norm or downside of sprouting them in a pot (as opposed to using a plastic filter with holes).
I wash the bean sprouts, put into a zip lock bag and put in the fridge. They should be good for a week.
This is my first successful harvest.
