If you want to get started in worm farming at home, then there’s one thing that you need – a worm bin. This is where the worms will live, along with the soil and other bedding materials, as well as the organic scraps that you will be feeding them. With too many options, deciding what to buy is difficult. Among others, one worth considering is the Urban Worm Bag Version 2.

Durable, breathable, and attractive – these are three of the words used by the manufacturer to describe the Urban Worm Bag Version 2. Are they right with their claims? Is it a worthy investment? There’s only one way to find out. Read the rest of this short review and learn from the insights we’ll be sharing below.


If there is one thing that sums up the design, it would be that it is incredible. We have used other worm bins in the past, and this one stands out. We are not saying that it is the best, but from its overall design, it demonstrates superior quality and functionality.


Create organic fertilizer inside or outside your home or apartment using nothing more than common household waste like newsprint, cardboard, and food waste.

Continuous Flow Design

One of the best things about the design of the worm bin is that it flows continuously. This provides better aeration for the soil while also simplifying the overall composting procedure. This is one thing that you will appreciate if you are a beginner. With the bedding in place, you will add the food scraps on the top and the castings will flow to the bottom.

Made Using Breathable Fabric

Another notable design feature of this worm bin is the use of breathable fabric as the main material. We have seen a lot of worm bins, and the common practice among manufacturers is to use plastic or similar hard materials. This model is made of a breathable fabric. This improves the aeration of the soil, and in turn, creates a healthy living environment for the worms. As it ensures proper ventilation, it also helps in the prevention of unwanted smell.

The fabric used in this worm bag is 900D Oxford. To make it even better, it comes with a polyurethane coating. The latter improves moisture resistance while also making the fabric more durable.

Robust Frame

It comes with a lightweight but robust iron frame, which will support the worm bag and everything that you will keep inside. The rectangular frame will keep the worm bin stable, as long as you put it on a level surface. The package comes with eight horizontal and four vertical supports, as well as three-way connectors. Once the frame is assembled, it has a height of 31.75 inches and a width of 26.75 inches.

  • Durable Construction: From the frame to the bag, the durability of this worm bin is unquestionable. We love how sturdy the frames are. The fabric of the bag is water-resistant. Plus, it comes with marine-grade zippers that are guaranteed to withstand the test of time.
  • Ease to Use: With the straightforward use of this worm bin, it is an excellent choice even for beginners. Worm composting does not need to be overwhelming when you have this product. You can complete the assembly of the frame within minutes. the best thing is that there is no need for screws. Just use the included connectors.
  • High Capacity: If you are looking for a worm bin with a large capacity, it is hard to go wrong with this product. The manufacturer claims that it has three times the volume that most of its competitors can offer. The bag can hold up to eight pounds of composting worms. Meanwhile, it processes up to four pounds of household waste every day. Even when the worm bag is full, the frame will not bow down because of weight.
  • Affordable: On a budget? Then you have another good reason to love this product. It is easy on the pocket but big in terms of performance. It is up to 1/3 cheaper compared to the all-plastic flow-through worm bins from most of its competitors. This is proof that you don’t need to spend a fortune to complete your worm composting set-up at home.


While we have good words to share about this product, to be fair, let’s also talk about some drawbacks.

  • Water Penetration Can Result in too Much Moisture: Being made of a breathable fabric can also be a problem. especially when the worm bin is outdoors, water can penetrate. It increases moisture in the bedding, which can also trigger the growth of bacteria. Make sure to put it somewhere it does not get wet.
  • Worms Can Possibly Get Out: Another weakness of this worm bag is that the worms can get out of the bag through the stitches. This is a common problem when the stitches wear out. The best way to prevent this from happening is to make sure that the stitching remains intact. Worms can also get out through the small gap when the zipper is closed. To prevent this, insert a cotton ball so that there is no space.
  • Can be Prone to Unpleasant Smell: This is one problem caused by the breathable fabric. Unlike its plastic counterparts, fabrics are known for absorbing moisture, and hence, it is inevitable that it will have a bad smell over time.
