Understanding Sprouting: From Seed to Sprout 

Seed sprouting or simply “sprouting” is the process that transforms a dormant seed into a vibrant, living sprout. This journey from seed to sprout is one of the miracles of nature that we can easily recreate in our own homes.

Sprouting can be done for most types of seeds, including peas, beans, lentils, and even grains like rice. You can grow sprouts at home, and it’s very simple to do, even in a small space. It’s not only easy, but the resulting sprouts can be used in a variety of dishes. 

Furthermore, homegrown sprouts are often vastly cheaper than store-bought sprouts. A new batch of sprouts should be started every week or two to keep up with your family's appetite for them.

By starting with seeds and sprouts, there is also minimal impact on the environment from food waste.

How to Sprout Seeds: Why It's Good for You

Sprouting is a great way to get the most out of your favorite seeds and legumes. Sprouting activates enzymes and increases the nutrient content of your food, making it more digestible, nutritious, and delicious. Here are some other benefits of sprouting:

Growing Sprouts in Jars: A Step-by-Step Guide 

One of the simplest and most popular methods to sprout seeds is in a jar. This doesn't require much equipment, and by following these easy steps, you can start the process of seed sprouting in your own home.

1. Choosing Your Jar and Lid for Sprouting Seeds:

 When picking your jar, consider the size of the sprouts you plan to grow. A jar with a wide opening is typically most convenient for rinsing, draining, and removing your sprouted seeds.

2. Rinsing Your Seeds Before Sprouting:

Rinse seeds well with cool water (around 70ºF) and drain. Remove any debris, stones, or broken seeds. When sprouting smaller seeds, removing broken seeds is not practical. But do look for any non-seed material and remove it at this point, if possible.

NOTE: Don't use cold or hot water—it could damage the seeds!

3. Soaking Your Seeds to Sprout: 

  • Place rinsed seeds in a jar and fill about ¾ full with cool water. Cover with amesh lid or cloth, secured with a rubber band, to allow airflow.
  • A general rule is to soak for at least 8 hours. Some larger seeds may require a longer soak. Soak until the seeds have doubled in size. Keep in mind that temperature also affects soak time. In warmer temperatures, the soak time is shorter. In cooler temperatures, soak time is longer, and larger seeds like chickpeas or kidney beans may require a 24-hour soak.

4. Draining Your Sprouted Seeds: 

Once your seeds have soaked and begun their journey from seed to sprout, it's crucial to drain them well. A well-drained environment is vital for healthy sprout growth.

5. Rinsing, Draining, and Repeating the Process for Sprouting Seeds: 

Rinse your sprouts with cool water and repeat the draining process, nurturing your seeds as they transform into sprouts. Usually, 2-3 days of rinsing and draining about 3 times per day are sufficient.

In very warm temperatures, rinse more frequently. In cold weather, less frequent rinsing may be fine, but keep in mind that seeds may not sprout as well. A temperature of about 65-80ºF for most seeds is fine.

6. Final Rinse and Drain for Sprouting Seeds: 

After your seeds have fully sprouted, give them a final rinse and drain. This prepares them for eating or storing, ensuring you get the most out of your sprouting efforts.


Utilizing Your Sprouted Seeds 

After successfully going through the journey from seed to sprout, yoursprouts are ready to be savored in a variety of ways.

Sprouts are ready to eat at any point after a sprout tail appears. Taste sprouted seeds daily and enjoy once they taste good to you. Many seeds will lose their mild flavor if sprouted too long. In general:

  • Sprout grains just until the sprout tail appears for cooking ordehydratingand grinding to flour
  • Sprout grains in a jar just until the sprout tail appears, and transfer to thesoil forgrowing grass for juicing.
  • Sprout legumes just until the sprout tail appears or before leaves appear.
  • Sprout seeds to the desired length, tasting daily.
  • Sprout seeds in a jar just until the sprout tail appears, and transfer to a tray for growing longer sprouts. Or transfer seeds to a tray with soil for growing microgreens.

Storing Your Sprouts and Sprouted Seeds 

Sprouts are easy to grow in small batches, staggered, so that there are fresh sprouts to eat daily. However, if storing is necessary, make sure the sprouts have drained completely before storing. Transfer to a glass or plastic container, seal tightly, and store in the refrigerator for a few days.

FAQs about How to Grow Sprouts in a Jar:

 If you're just starting your sprouting journey, you probably have a few questions. Below, we've provided answers to some of the most common questions about how to sprout seeds.


It depends on the sprouts! Some sprouts, like alfalfa, chickpeas, and green peas, can take as little as three days to grow. Others are slower growers, like beet or sunflower seeds (which can take two to three weeks to sprout).

Secondly, the quality of your seeds will affect how quickly they sprout. If your seeds are old or have been improperly stored, they'll take longer to germinate. The best way to know how long your sprout will take is to check out the package or online resource for that specific type of seed. 


You can grow almost any kind of sprout in a jar! Bean and pea sprouts, sprouted grains, and sprouts from vegetables, nuts, and other seeds are all popular options. Here are a few suggestions:

  • Alfalfa sprouts
  • Broccoli sprouts
  • Mung Bean sprouts
  • Beet sprouts
  • Chickpea sprouts
  • Red Clover sprouts
  • Mustard sprouts
  • Green Pea sprouts
  • Kale sprouts
  • Lentil sprouts
  • Radish sprouts
  • Sunflower sprouts


It depends on the type of seed, the type of sprout you're growing, and the time you're planning on keeping the jar. In general, though, it's good to start with two tablespoons of seeds for each quart-sized jar. This will fill your jar with sprouts so that you can enjoy them for days!



If you're a beginner, it’s best to use seeds sold specifically for sprouting. Sprouting seeds are specially manufactured to be free of certain chemicals that can harm our health. Therefore, only buy seeds intended for sprouting use. We can help provide some of thebest sprouting supplies and seeds to sprout for your home use.


Sprouts don't need sunlight to grow, but they do need some light to photosynthesize and produce their own food. Make sure not to put your sprouting jars in direct sunlight. This can cause your sprouts to become too hot. Room light should be enough for most of their growing process.


Lentils and mung beans grow the fastest, sprouting in as little as three days. Alfalfa, chickpeas, and adzuki beans need a bit more time to grow, sprouting between three to five days.


You can eat your sprouts straight from the bottle if you’d like, you can add them to a salad, or grow them in soil and add microgreens to a sandwich. We’ve got lots of great recipe ideas if you’d like to experiment or have some extra sprouts to use up.
