Hanging Sprout Jars

Introduction: Hanging Sprout Jars

About: I'm a refugee from Los Angeles, living in backwoods Puerto Rico for about 35 years now and loving it. I built my own home from discarded nylon fishnet and cement.

Sprouts are good, nutritious food.  The ones shown here are mung bean sprouts.  They are raised by just keeping them moist while they develop.  No dirt is used.  The finished sprouts are eaten roots, stem, and early leaves.  I eat them raw, as salad material, but I believe they can also be eaten stir fried, as in Chinese food dishes. 

I got the mung beans from a health food store.  Probably other beans, or lentils could also be sprouted and eaten, but my experience is limited. 

One person I knew years ago supported himself with two hours of labor a day by raising alfalfa sprouts in jars.  The jars were in a rack in his closet.  It was sort of like an assembly line.  New jars got started every day and the oldest sprouts got packaged in baggies and sold to local markets.    

I make wire cradles with handles to suspend the jars in the air with hooks from a pipe.  The original pickle jar lids are modified to hold stainless screen which holds the sprouts in while letting them drain off excess water.

It takes about a week to go from seed to ready-to-eat sprouts, moistening the sprouts two or three times a day. 

Step 1: Cutting the Lid Ring

The lid ring is the outer part of the original jar lid.  A circle is cut out of the center of the jar lid by drilling a hole in the metal and then using a "nibbler" tool to cut the circle out of the center. 

The nibbler is a tool I don't use much, but for this kind of job it does a very good job.  It takes baby bites of the material every time you squeeze the handles.  

I got my nibbler many years ago, possibly from Home Depot. 

The wire screen circle gets held to the top of the jar by this ring. 

I have a little stainless steel screen material that was given to me years ago by a museum staff friend of my mother's.  It is not a common material and I am not sure where I would get more today.  I don't live in a big city, and that is probably a specialty item.  A Google search for stainless steel screens will result in some possible Internet sources.

Without stainless steel screen, I would probably substitute cheese cloth or mosquito netting for it.  A layer of cheese cloth might be held by the lid ring.  If not, the cheese cloth might be held with rubber bands or string, instead of the lid ring. 

I would avoid possibly toxic materials such as aluminum screen.  I consider aluminum to be possibly toxic because of some associations with Alzheimer's disease and levels of aluminum.  My preference is to not cook with aluminum pots.  Others may feel more comfortable with the idea of using aluminum for the screen, but I'm just a little cautious. 

Step 2: The Hanging Wire Cradle

I used two pieces of galvanized iron tie wire about 7 feet long to twist around the jar and to make the handle.  The handle is made of the free ends of the wire twisted around each other. 

First, I twist them around the mouth of the jar (1a,1b), leaving the four ends sticking out, two on each side.  I join one from each side of the mouth at the next two twist areas on the sides of the jar (2a,2b).   Then, one from each of those pairs gets joined at the next twist area, near the bottom of the jar (3a,3b). 

I then take the four wires as two pairs and twist them around each other to make the handle.  Start at the top center of the handle, hold them together with pliers, and twist one pair around the other pair.  Then twist the other pair around the remaining side of the handle.  The ends of the wires end up near the glass.  Use pliers to pinch the ends around to eliminate sharp wire ends. 

The next step is to raise some sprouts and chow down!  I like them as raw salad material with a little oil and vinegar, or vegetarian mayonnaise as lubricant.  I also love a little curry on them.

    Hi, I tried out your concept and it works fine!

    Meshes / screens with a 1.5 to 2 mm grid seem to work best, when you have no seeds which are smaller. Finer screens tend to seal themself (when wet) for incoming air and outflowing water due to the surface tension of water.

    I also stumbled upon your improved version, feel free to have a look at what I made out of it:

    Thanks a lot for the inspiration you gave to me, with all of your instructables!

    Best regards,

    That is a nice way to hold the jar, just so long as the jar doesn't slip out, or the rubber break. Thanks for the link to your instructable.

    once we wired the jar, do we put the bean sprouts in the jar with the lid tighten, upside down?  do we moist the bean sprouts before we put them in the jar and do we continue the moisten them?  how do bean sprouts grow?  these might be silly questions but it does not hurt to ask, right?  thanks!

    Very good questions, fortunately all with answers. 

    I put the mung beans in the jar, mouth up, so that they can soak in water for about 12 hours.  They swell up in size and the growing sprout splits the skin of the seed as it starts to emerge.

    After that, I hang the jar upside-down by the handle and let it drain.  Two or three times a day I cover them with water and then leave them upside-down to drain again.  The sprouts don't want to dry out or they will die and start to rot.  Without adequate drainage, they will also drown, die and start to rot. 

    It's that happy medium range with adequate humidity but not too much where the beans do best. 

    How do bean sprouts grow?  Magic.  They are alive.

    They get the nutrients they need for growth from the air, water, and the seed itself.  As they evolve, their nutritive value for us changes, also.  I don't know the chemical details.  More enzymes and vitamins, perhaps.

    that is awesome.  thank you very much for explaining this whole process in details.  i just do not want to make mistakes growing these or waste them.  thank!
