Recycle Our Mason Jars | How to Grow Microgreens & Bean Sprouts in a Jar

Use this blog to learn how to recycle our jars for growing your own microgreens and bean sprouts! 

We've REALLY gotten into growing microgreens in jars lately. We've mostly been sprouting various types of lentils plus some mung beans, but we just sprouted our first batch of organic broccoli seeds, alfalfa seeds, radish seeds, and clover seeds... and they are so delicious!

Did you know that bean and seed sprouts are fantastic for gut health? Since Jon and I live a plant based lifestyle, we eat a lot of sprouted seeds and beans for a healthy (and CHEAP! ) source of protein. The BEST part is: when sprouted, beans and seeds do not cause nearly as much gas! Since Jon and I live a plant based lifestyle, we eat a lot of sprouted seeds and beans for a source of protein and lots of vitamins. Bean and seed sprouts are a significant source of B Vitamins, Vitamin K, Vitamin C, Iron, Folate, and especially fiber.  


Sprouts are one of the best prebiotic foods you can eat because of the amount of available fiber and nutrients that make it to your gut to feed your microbiome. When you provide your gut microbiome with all of these great compounds, nutrients, and fiber the microorganisms thrive. They can even create more healthy compounds and antioxidants from the sprouts!

These healthy compounds can help to keep your whole body thriving by aiding in cancer prevention, reducing inflammation, and lowering blood pressure! 

The easiest, affordable and eco-friendly way to start sprouting seeds and beans is to create your own seed sprouting jar! It's REALLY simple and we love upcyling some of our used Cultured Guru Fermented Food jars to make them!

What You'll Need to Grow Bean Sprouts and Microgreens

  1. 2-3 Clean Empty Cultured Guru Jars or any mason jar

  2. Plastic Canvas like this  OR a mesh sprouting screen like this OR cheesecloth

  3. Raw dried lentils (any type), mung beans, chickpeas, adzuki beans, broccoli seed, alfalfa seeds and radish seeds. 

We get all of our beans and lentils for sprouting from the bulk section of Whole Foods. Their beans and lentils sprout beautifully. We highly suggest getting them from there. As for seeds to sprout, you can buy some on amazon or order them from organic bulk suppliers like this

* NOTE: Do not use seeds from a gardening center to grow sprouts. 

If you order a mesh screen or are using cheesecloth you are ready to sprout beans and seeds! 

Here’s my favorite seed and bean sprouting supplies:  


Making a Jar for Bean Sprouts and Microgreens

Using a regular two piece canning lid that fits your jar and a permanent marker, trace the lid (not the outer securing band) onto the plastic canvas. Cut out the circle.  This circle will replace the lid to a normal mason top and can be secured using the ring portion of the lid. 

Sprouting Beans and Seeds

Growing Bean Sprouts and Microgreens in a Jar

1. Rinse 1-2 Tablespoons of beans or seeds using a fine mesh strainer.

2. Add the rinsed beans/seeds to the jar.

3. Fill 3/4 with cool water .

4. Place the sprouting lid of your choice on the jar. If using cheesecloth, secure with a rubber band. 

4. Place the jar upright, out of direct sunlight on the counter. Let soak for 24 hours.

5. Using the sprouting lid of your choice as a sieve, drain the water off and rinse twice. 

6. With the sprouting lid on, and all water drained off, place the jar on a slant upside down. This can be done in a bowl, or in your sink drain. 

7. Rinse every 12 hours using the sprouting lid as the sieve, and allow to sprout for 3-4 days. By the 2nd or 3rd day you will start to see shoots coming from the seeds or beans. 

8. After they have sprouted to your liking, rinse well, replace the lid with a normal sealed lid and refrigerate. 

Happy Sprouting!
