Sprouts are easy to grow and this is a method my parents figured out.
My dad cut a screen of some sort the size of a wide mouth mason jar.
It is an easy, inexpensive way to grow sprouts without buying a kit. Because it is so tall you will need to rinse it frequently.
First, put a TBL of seeds in the jar, fill it with water and wrap a towel around the jar. This is to prevent the seeds from turning green in case you want to do it for a homeschool lesson)
Fill the jar with tepid water and soak overnight.
Rinse with tepid water each day. You will notice growth in a day or two.
Not every seed will sprout but when the majority are a good size, remove the towel and let them grow for another day unwrapped.
You will need to eat them or refrigerate them at this point.
