Commentary from Sproutman
I discourage the use the jars for sprouting. While they are cheap and available, they were never designed to be gardening tools. In fact, they are the #1 cause of sprouting problems. This is because they create a perfect environment for the growth of mold. They don’t drain adequately, or breath sufficiently. Mold and mildew growth are common in jars because of these limitations. I invented the fabric sprout bag as a substitute for jars.
1. Soak your seeds in a jar of pure water overnight (about 8 hours).
2. Pour out the soaking water through a strainer affixed to the top of the jar.
3. Lay in dish rack or dishwasher rack at an angle with the top of the jar leaning slightly down. 4. Rinse with fresh water twice per day. Jars are ideal for bean and grain sprouts which take 3-5 days to mature.
