Compared to a lot of places, Hong Kong is relatively hot and humid. This may affect the growth of sprouts and make your sprouts quality drop dramatically. We have to drain our sprouts very thoroughly especially if we are not sprouting at the place with air conditioner turned on.
Fortunately, we can still grow good sprouts at room temperature and relatively humid environment by adding a simple step after the usual rinse and drain.
To keep your sprouts dry, simply put the jar on a medium bowl to allow excess water to drain while still letting air circulate (as shown below).
After few days you can harvest crunchy and tasty sprouts.
