Growing Sprouts in a Mason Jar Provides Quick, Fresh Nutrition in Winter

Tired of winter?

Looking for fresh local produce?

Make your own by growing sprouts in a mason jar!

You can grow your own sprouts very quickly and easily with almost no equipment! 

You don’t need grow lights. 

There is no soil or plant starter mix to make a mess. 

Furthermore, sprouts are full of all the nutrition the seeds had stored up for the new plant, including lots of protein.

All you need is:

1. a mason jar,

2. a sprouting lid which you can make yourself

3. and some seeds.

A Mason Jar

You can use any size mason jar, but since the sprouts are best fresh, several smaller jars are better than one large jar.  You can stagger your jars by 2 or 3 days in order to have a steady supply.

A Sprouting Lid

Although sprouting lids are readily available online, you can easily make your own with plastic canvas from your local craft store.  If you will be planting large seeds such as mung beans, plastic canvas with 7 holes to the inch is fine, but if you are going to use smaller seeds such as alfalfa, you need 10 holes to the inch so you don’t lose the fine seeds.


You should avoid using treated seeds for sprouts because you don’t want to eat the fungicide that the seeds were treated with.  As long as your seed is untreated, almost any seeds can be sprouted but some seeds are better than others.  Alfalfa and mung beans are common choices for sprouting because they sprout fast and are nutritious and tasty.  Many seed companies sell mixes that could include seeds from alfalfa, broccoli, radish, and other interesting plants to add flavor and variety.

Growing sprouts in under 5 days

Before you start, it is very important to make sure everything is clean.  Hot water and lots of soap should be used to clean the jar and lid. 

Pour about one tablespoon of seeds into your jar, put a couple of inches of water in the jar, and put it in a nice warm spot out of direct sunlight.  The top of a refrigerator near the back is an ideal spot.  (This presoaking is especially helpful for larger seeds.)

After a few hours of soaking the seeds, drain the water thoroughly, rinse the seeds with more water, and drain them again. 

Set the mason jar in a small bowl at an angle so that the remaining water can drain from the seeds, and return the jar to a warm, shaded spot. 

Twice daily, rinse the seeds a couple times, and place them to drain in that warm, shaded spot.

In 4 to 5 days, your sprouts will be ready to eat.  Any sprouts that can’t be used immediately need to be refrigerated and used up within two to three days.

Avoiding potential problems

The one risk to growing sprouts at home is the development of mold.  This risk can be easily mitigated by starting with super clean equipment, rinsing your sprouts twice daily and leaving them to drain, and then consuming or refrigerating finished sprouts immediately.

If your sprouts are looking a bit pale, put them in a sunny window for two or three hours to green them up but not long enough to let them burn.
