Description

Uncle Jim’s is proud to offer THE DURABLE, BREATHABLE, ATTRACTIVE HOME WORM BIN SOLUTION!

Create organic fertilizer inside your home or apartment using nothing more than common household waste like newsprint, cardboard, and food waste. Let composting worms eat the waste you place in the top and you collect the castings from the bottom! Easy peezy and mess free!
The perfect combination of simplicity, breath-ability, and durability.

1. DURABILITY

  • At capacity, your Urban Worm Bag will hold up to 120lbs or more of dense vermicompost with a moisture content of 70-90%.
  • To withstand these conditions, 900D Oxford nylon fabric that won’t rip or abrade, even in the harshest of environments conditions is used on every worm bag.
  • Only the highest-quality, waterproof nylon “overseam” stitching and marine grade zippers are used.

2. BREATHABILITY

  • Vermicompost is its own living ecosystem, potentially full of beneficial bacteria, fungi, hormones, all standing ready to breathe life into your soil.
  • Your composter needs to breathe too.
  • The Urban Worm Bag’s fabric construction helps you maintain aerobic conditions throughout the entirety of your vermicomposting process.

3.  SIMPLICITY 

  • The Urban Worm Bag uses the highly-efficient, but incredibly simple continuous flow concept found in the world’s top vermicomposting operations.
  • Unless your vermicompost contains fibrous or woody material, your finished product could be ready to use as-is.
  • No screening. No sifting. Just apply to your plants, soil, or growing medium.

Frequently Asked Questions

HOW LONG UNTIL I CAN BEGIN HARVESTING WORM CASTINGS?

If you start from scratch, it should be about 4-6 months before you should expect to harvest worm castings from the bottom of your worm bag. You can reduce this time (and better ensure a happy home for your worms) if you start with an existing amount of vermicompost as a starter material.

HOW DO I MAINTAIN PROPER MOISTURE IN MY URBAN WORM BAG?

This will depend on the ambient humidity wherever it is you keep your bin, whether or not you keep it indoors, and whether or not you keep it in your basement.

The Urban Worm Bag breathes so well that it can tend to dry out too quickly if left neglected.

In any case, if you grab a handful of vermicompost and squeeze it, you should be able to squeeze out a drop or two of moisture, much like a well-wrung out sponge.

If it’s too wet, add some dry bedding and stop feeding for a few days.

If it’s too dry, use a spray bottle or spritzer as needed to maintain appropriate moisture levels.

WHAT IF MY URBAN WORM BAG HAS A FOUL SMELL?

A properly maintained worm bin should not smell bad. More than likely, the bin is over fed, too wet, or both. Because the Urban Worm Bag has such good airflow, it is likely your bin has been overfed and the food is decomposing faster than the worms can consume it. Remove any excess food, add bedding, and monitor conditions.

HOW MUCH VERMICOMPOST OR WORM CASTINGS CAN THE URBAN WORM BAG PRODUCE?

Your results are dependent upon too many variables to give you a good number.

However you can use commonly-known rules of thumb to get a very rough estimate. Conservatively, worms can eat 25-50% of their own weight per day and at maximum density, you will have around 2 lbs of worms per square foot.

The Urban Worm Bag has roughly 4 square feet of surface area. So an Urban Worm Bag stocked with 4lbs of worms will be able to process roughly 1-2 lbs of food waste per day under good conditions, roughly 50-70% of which will exit the worm in the form of worm castings.

MY URBAN WORM BAG IS DRIPPING. WHAT IS HAPPENING?

Your Bag has been overfed or overwatered. A properly-maintained Urban Worm Bag, or any worm bin for that matter, should not be draining an excess of water, also known as leachate.

IS THE URBAN WORM BAG RODENT-PROOF?

Unfortunately, no. This worm bin should be kept indoors, preferably, and away from rodents who will certainly be able to chew through the fabric.

The Urban Worm Bag *should* be used indoors, but depending on location, it may be used outdoors. In all cases, it must be protected from exposure to sunlight and precipitation.

HOW CAN I USE MY WORM CASTINGS?

This is up to you! But most people prefer to use worm castings and a soil amendment at a 10% substitution rate or apply it directly to the base of their plants as a top dressing. Note: This will not burn the plants.

You can also brew worm tea by mixing water and a compost tea bag of worm castings at roughly a 1% concentration and apply as a soil drench or a foliage spray using a handheld low-pressure sprayer. This is an incredibly economical way to use worm castings.

Dynamic Duo!

I’ve readily assembled one unit inside a spare room that I use for storage. I wanted to get one going to learn how to do properly inside and so far so good! I’ll set the second up later. I felt the instructions were great and the worms came separately but all alive and ready to tackle their new home munching away! The only caution I have is that I did not fully reverse the black cloth bags with the worms into the new container so did not realize that about 20-30 were still based on the bottom of the shipping bag. The next day - I found about 30 dead worms who had crawled out of the ship bag to the floor looking for home and died trying. I felt horrible for not realizing I had not checked the ship bag better so a notice and reminder might help newbies to really check you have dumped all your worms out into their new home! Otherwise - great experience, product, service and education to make the most of your composting adventure! Still learning but loving the process here in Oregon!

Great bag!

I really like the concept of composting with the worm bag system & am anxious to see how it goes. I also ordered worms, coir, & a “blanket” which unfortunately came several days before the worm bag so by the time the bag kit got here, the poor worms were not in great shape. I did add a bit of water to their shipping bag they were in & kept them tied up in bag & box in basement to try to have some to get things started when bag was finally here & ready for them.

Up and running

The initial set-up had a hitch of getting the support structure to lock in place. If you can have a second person to help you, this would also be beneficial. The booklet was helpful and a nice resource. It does take up a large footprint in my garage, but I can put small items underneath. I like the cover blanket with it's handle to help lift it.

Wonderful once I worked out the kinks

Now that everything’s present and functional, I love this worm bag! Through no fault of mine or Uncle Jim’s, the bag arrived later than my worms (I received superior customer service from UJ in the interim.) Then, I was too hasty in assembling it, so the bag crashed down unceremoniously. Now that everything is stable, it’s working well! There’s only a slight earthy smell when the bag is fully unzipped and the flap is open. Everything is easy to use, and the included instructions and composting guide are very helpful in addition to the Uncle Jim’s team. I keep this in our kitchen for easy access and am looking forward to a healthy garden this spring!
