The latter four products may also help prevent the growth of bacteria. The ideal sprouting temperature is between 65 and 75 degrees. When sprouted too long, some seeds and beans become bitter. Grains become sweeter on the fourth and fifth day. Placing sprouts in direct light on the last day of growth will develop chlorophyll, which has healthful qualities.
Sunlight also triggers the production of carotenes.
Sprouting can be done year round, so it is especially valuable in the winter months. Just keep in mind that in the cooler months things are going to take a little longer. Below 60 degrees fewer seeds germinate and sprouts grow more slowly. If you store mature sprouts in an airtight jar or plastic bag in your refrigerator, they will stay fresh for about a week. To take it one step further, you may also plant a variety of seeds and offer fresh grown greens to your birds.
