Sprouting jars are about $20 in your local healthfood store.
Instead, pick up either a sheet or a pre-cut plastic needlepoint canvas from your local dollar or craft store and cut them to fit the top your Mason jar and screw on with the canning ring!
Ta-Da!
Now you can sprout your seeds for salads or to start seeds for your garden in it!
Sprouting also has a lot of appeal to me. You don't really need all the commercial items available to sprout successfully!
How do I grow alfalfa sprouts without buying the growing kit? I bought organic seeds, but I am not sure how to grow them at home.
