How to Make your Own Sprouting Jar

I am not able to grow anything in the garden from October through early May.  I do use a cold frame to extend our growing season a few weeks longer, but even with that, there’s a long time that I don’t have vegetables in the garden to pick. 

Learning how to make your own sprouting jar will provide very low-cost fresh greens throughout the year, even when it’s below zero outside.

You can buy a variety of different pre-made sprouting kits or sprouting bags at many local food co-ops.  I checked out the prices last time I was there and realized that I could make one for much less money.  

You can sprout many different types of seeds in sprouting jars.  Each has a different taste so experiment a bit to find out which one you most prefer.

Depending on the size of the seed you are sprouting, you may need a different size mesh on the top of your jar.  You can choose a coffee filter, cheesecloth or cotton for small seeds, screen for medium, or plastic canvas mesh for larger seeds.

How do I start sprouting at home?

I use a Mason jar to sprout my seeds.  In the past, I have sprouted mung beans and used a quart-sized Mason jar.  

This time, I am sprouting alfalfa seeds and chose a pint-size Mason jar because they are smaller. Make your choice based on the size of the seed and how many seeds you want to sprout at once. You can use standard or wide-mouth Mason jars.

Materials

  • One Mason jar
  • One Mason jar lid with ring

Directions

Wondering how to make your own sprouting jar? Follow these steps.

  • Wash and dry the Mason jar and jar ring
  • Turn the Mason jar lid upside down and trace around the outside on your coffee filter, cheesecloth, screen or mesh.
  • Carefully cut the circle of material out and fit it inside your jar.

When you sprout seeds, PLEASE choose organic seeds or beans for health reasons.  Sprouting seeds that may have been treated or sourced from plants that have been treated takes away any health benefits of eating them.

Once the jar has been created, place about two tablespoons of seeds in the jar. The amount you use will vary based on the size of the seed. Leave enough room for them to grow.

Fill the with water to about one inch higher than your seeds. Put the ring and top on and place it in a cool spot that isn’t in direct sunlight overnight.

Now that you know how to make your own sprouting jar, you need to wait for them to sprout.

The next day, carefully drain out the water in the jar through the screen top.  Set the jar on its side in a cool spot that isn’t in direct sunlight again.

Two or three times a day, you will need to rinse the seeds with water.  Just put water in, swish the water around, and then drain the water out.  

Set the jar on its side again in between each rinsing.  Continue the process until the seeds are grown to the size you want them.

Seeds should take about four or five days to sprout so plan your next crop accordingly.

  2. I have done something similar when I was a kid. Teachers taught us to grow sprouts in a cup using some water and water but a jar is even neater!

  5. Love this! Very cute. I would try it, but I seem to kill anything – including air plants. I can’t wait to see the sprouts. Please share when they start.

  6. I love sprouts and have never thought to grow them myself. This is such a great idea, the only thing I worry about is do they get smelly? We had an herb garden awhile back and it got smelling so bad we had to throw them out. If this is a way to grow these without all the hassle I’m so in!

    • Hi Amanda – They should not get smelly at all ever or they aren’t any good 🙂 You are only sprouting for about 4 days and then cleaning the jar and starting over again.

  9. When the kids were little, they grew sprouts at school but I couldn’t remember what kind or how. I’ve tried some on sandwiches at restaurants and LOVE it but have never purchased them or made anything myself. If it’s easy, maybe I will.

  10. Sprouting seeds looks like something my kids would enjoy helping out so they can watch. I have a dumb question – but what do you do with the sprouts once they are growing? Are these like the sprouts you put on sandwiches?

  11. I am amazed at how you manage everything, the longer I read your blog and “follow” you, you’re just impressive. This is so cool! Can’t wait to see them grow.
