A jar, 1 litre to 4 litre (1 qt. to gallon) size, depending on your appetite for sprouts.
A bowl or something that allows you to invert the jar at an angle.
Some screen or netting with a rubber band
Fresh water. If you would drink the water than it is fine to use!
Seeds with good germination, preferably grown organically for human consumption.
There are also numerous other methods such as a SproutMaster Tray or Hemp Bag. It's as easy as following the directions provided!
Next, Soak the seed:
If you have chosen to sprout in a jar you can soak the seed in the same jar. If not, any sterile container will do. Use about one cup of water to every tablespoon of seed.
Broccoli and related plants cabbage, kale, radish etc. 2-3h
Other small seeds 2-6 hrs.
Large seeds peas, lentils, grain, etc. 6-12hrs.
Mucilaginous seeds cress, arugula, chia, flax, basil - do not soak, just mist to keep moist.
Remember, these are ideal soak times but if in doubt soak less rather than more. If you do over soak, just carry on. Sprouts are very forgiving!
Rinse and drain 2 or 3 times each day with fresh cold water and invert the jar on angle to allow excess water to drain.
And lastly. . . Enjoy!
Place the finished sprouts in as sink of cold water and swirl to separate the hulls. The hulls are fine to eat but your sprouts will look much better without! Remove sprouts by the handful, rinsing under the tap. Most hulls should be left in the sink. Drain the sprouts and allow to dry for a few hours before storing in fridge.
There are as many ways to grow sprouts as there are varieties of seed. Do what works for you and make it your own!
