Create organic fertilizer inside or outside your home or apartment using nothing more than common household waste like newsprint, cardboard, and food waste. Composting worms eat the waste you place in the top and you collect the castings from the bottom.
This is the same "flow through" concept used in the world's top vermicomposting operations.
A combination of simplicity, breathability, and durability.
Volume at Max Load:5.3 cubic ft (122 liters)
Fabric:900D Oxford with a polyurethane coating for moisture resistance
Frame:Lightweight iron frame with plastic 3-way connectors
Zippers: Marine-grade #8 heavy zippers
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.
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.
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.
A new edition of the definitive guide to vermicomposting--a process using redworms to recycle human food waste into nutrient-rich fertilizer for plants.
Author Mary Appelhof provides complete illustrated instructions on setting up and maintaining small-scale worm composting systems. Internationally recognized as an authority on vermicomposting, Appelhof worked with worms for over three decades before her death in 2005.
Topics include: bin types, worm species, reproduction, care and feeding of worms, harvesting, and how to make the finished product of potting soil.
About a year ago, I watched a fascinating time lapse video of the assembly of one of the most attractive continuous flow vermicomposting systems I have ever seen. Some guy named Dan Lonowski of Michigan SoilWorks and Gavin Newton of Detroit-area worm castings producer WormCycle were putting together a 16-ft CFT for use in Gavin’s […]

It seems to happen again and again and again.
Armed with a bin, some bedding, and a shiny new arsenal of composting worms, eager new vermicomposters, our fellow foot soldiers in the War on Waste try to win the war literally overnight.
And they often fail miserably.
Who can blame them? Our intrepid brothers-in-worms have not learned the crucial lesson a vermi-boot camp worth its salt would teach you; that overfeeding is the most common cause of problems in the worm bin.
The grossly over-optimistic rule of thumb that worms can eat 50-100% of their weight in organic waste each day is leading new vermicomposters to certain failure. So it’s high time we explore some common problems in worm bins and reverse engineer how overfeeding can cause each one of them.
Before we begin, it’s worth noting that overfeeding will not necessarily lead to ALL problems below.
But when the first step to solving the problems below is normally to STOP FEEDING, it should serve as a wakeup call that overfeeding is probably the start of most of our problems in the first place.
Some of us start vermicomposting to divert our household or farm waste away from the waste stream, and that is a benefit by itself. But what about the end product? If you’re reading this, you’re probably already aware that vermicompost, which includes the worm castings plus undigested organic matter plus a plethora of soil-enhancing goodies, is […]
