## Description

Recycle Organic Waste and Make Vermicompost or Worm Castings with the Urban Worm Bag - | Breathable Material Keeps Your Worm Farm Aerobic | Strong Iron Frame Included | Feed from the Top, Collect Ready-To-Use High-Yield Organic Fertilizer From the Bottom To Use in Your Garden or Growing Operation After the incredibly simple 5-minute assembly instructions, just follow the easy start-up direction and start composting using a bed of moist, carbon-based household waste like saturated cardboard or newsprint. Coco coir and aged horse manure is an excellent choice, but for best results, start with existing vermicompost. The Urban Worm Bag can process non-dairy, non-meat household waste and turn it into a potent organic soil amendment or fertilizer right in your home. Featuring 4 sq ft of vermicomposting space and over 5 cubic ft of volume, an Urban Worm Bag at max capacity can hold up to 8 lbs of composting worms, processing up to 3-4 lbs of household waste per day. -- *How long until I can harvest 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 Urban 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. *What are the specs on the Urban Worm Bag?*﻿﻿Width: 26.75-in Length:26.75-in Height: 31.75-in Bag Only Height:22 in Bag Only Width:24 in Bag Only Length: 24 inWeight:7.5 lbsVolume at Max Load:5.3 cubic ftFabric:900D Oxford with a polyurethane coating for moisture resistanceFrame:Lightweight iron frame with plastic 3-way connectors

Review: 100% Must Have - This is the gold standard of home composting—hands down. The Urban Worm Bag is not just a product, it’s a lifestyle shift. I’ve tried bins, totes, DIY systems—you name it—and nothing compares to this setup. From day one, I knew this thing was built with intention and quality. The fabric is strong, breathable, and holds moisture at the perfect level. The airflow is excellent, which means no smells, no overheating, and a healthy worm colony that’s thriving. The zipper access makes harvesting castings ridiculously easy—no mess, no stress. Just unzip, scoop, and boom: black gold. Setup was a breeze. Once you get your bedding layered right (shoutout to coir, shredded paper, and crushed eggshells!), the Urban Worm Bag basically runs itself. Add scraps, keep it moist, and the worms do all the magic. It's expandable, tidy, and looks good in any corner of the garage or porch—no gross plastic bins leaking mystery goo. This thing has become a core part of my garden ecosystem, my soil-building plan, and my daily rhythm. I check on my worms like a proud parent. If you're even thinking about vermicomposting—stop thinking. Get this bag. 10 out of 10. Would buy again. Will never need to. It’s that good.
Review: Why did I wait????? - Update 2021: I still love this thing. My worm population has grown substantially. The seam of my second bag split when I went to zip it up and while contemplating what to do next, the Facebook fan group said it was still under warranty. Amazing! I contacted Steve and he’s sending me the third version of the bag. In the meanwhile, I emptied my second bin (with much less worms as it takes that bin three or four times longer to process the same amount of food) into my first bin and now my first bin is full to the top. I’m thinking of leaving them there for maybe six months before splitting the bins again. When I emptied the bin, I put the contents into my first bin from the top, until I got to the layer that was more castings than bedding. I harvested two gallons of castings in this way. I normally harvest half a gallon from my first bin every three to six months (I started with only enough worms for a four gallon system). Worms are so expensive here in Hawai’i, there is no other item in my house that pays for itself like the Urban Worm Bag. While you can get away with not spending money on a worm bin, the time you save sifting castings is substantial and absolutely worth the time spent and strain on your body you mitigate. The volume of it considering is amazing, especially when you factor in the amount of space it uses. Let’s talk about Steve for a moment. Between his presence in the fan group, his blogs and YouTube channel, his quick response and excellent customer service, I can’t think of another owner that is so approachable, responsive and stands by his product. Considering that worm bins mitigate trash that could have ended up in a landfill and recycles valuable resources, I admire the guy quite a bit. On to practical advice. My little worm bins and my larger tote were all in plastic containers. The UWB is breathable cloth, so a new system (or a slow system, like my second bin that started with just 50 worms or so) is going to take some effort to maintain proper moisture. New bedding dried out faster than castings. I found my second bin would have dried spots of bedding in the corners, so I had to dig around and mix those spots frequently. My first bin got over the moisture issues much faster. This is the main reason I’m going to let my combined worms sit for several months before splitting. Feed in pockets and make sure to check the previous feeding sites (I feed using the clock to remember. 12, 3, 6 and 9). Feed when the previous site has a worm ball and the site before that is gone. Being cautious when feeding is important in a new bin, once the bin has been established (6-12 months), you can get more experimental. The bin should never smell anything but earthy. Any scents otherwise means you should cut back feeding. My worms were slaying their feedings, so I put a whole mini watermelon in there. Smelled awful in about a week. Only time that’s happened to me. I broke it apart and put some into my second bin and by the time I checked the following week, no smell. The first few harvests will contain worms. After that, it won’t. Just setting expectations. Why is this? You put bedding into the bin at first and it’s all at the same level of being processed. Worms wander around and leave cocoons. Those worms hatch and if the spot they’re at is moist enough, they’ll hang out. As the bedding is processed, you add another layer of fresh bedding with your food. Worms move up to follow the food. The higher layers are also larger and as they go down, they get compressed into a smaller area. So the layer you feed a few inches from the top will take a VERY long time to work it’s way to the bottom, unlike the first few harvests that started at the bottom. There just isn’t as much time for the worms to travel at first, but once the process starts, you’ll have worm free harvests. Especially if you open the bottom before you harvest and make sure it is running a little drier than the rest of the bin. I will absolutely buy a third one, at full price, once my other two are full. By that point, I’d be processing a LOT of produce and I’d probably be able to stop at three for my fruit loving household of four. Original 2019 review: I got my first worms two years ago. They are expensive here in Hawaii and illegal to import from out-of-state, so I got a handful from friends. I had visions of composting everything eventually, but my homemade tote was too big for the amount I had and other critters moved in. I scrapped that project and went down to a 1-gallon bucket. Easier to manage and I expanded to 3 buckets but harvesting was always a pain. I knew about CFTs and thought to make one myself. $30 for a sturdy enough garbage can, hopefully repurpose some pipes, but there's the time it takes, figuring out where to put it, when will I have time with two little kids.... Wheelie bins would have been ideal but ..... Anyway, as you can see, I've over thought the process for quite a while. And kicked myself for not jumping on the UWB2 when it was on sale for $89 on Prime day. Which is funny because there was an insane moment when I thought of getting the hungry bin two years ago. I think that's why I had it in my head to make my own. If I had known about the UWB, I would have thousands of worms already. So anyway, I ask Steve if he'll have another sale in a few weeks so I could be ready and he sent me a coupon. What a great guy. I bought it and it was so much bigger than I expected! So pleased! It was ridiculously easy to put together. In fact, turning it and pressing the joints in more over and over until they couldn't be pushed in anymore took longer than putting the pieces together. Also, I shred all the packaging to put in the worm bin, so no plastic waste. It's been going well. I live in a temperate area and I'm composting with blue worms. They're in the shade on my lanai. I followed the instructions for letting the moisture equalize for a couple of days before adding the worms, I Spritz the top every couple of days because the top bedding dries out in my location (did the same with the buckets, I don't get it since it's so humid here). I have no idea how hard or heavy it will be once there's castings to harvest, so I'll have to come back and edit once I've done that. But I'm looking forward to picking out as many worms as I do to harvest my little buckets. Oh, and this Prime Day (2019), it went down to $89 again PLUS an instant coupon. So, now I have two.

## Questions & Answers

**Q: Will worm castings sold in a bag work for "starting with vermicomopost"? How much does starting with vermicompost speed up the process?**
A: I have been vermicomposting for over ten years and I (for some reason unknown to me) love it. Worms eat my garbage. 
I think you might pull that off and here is how. 
Start by putting a layer of paper in the bottom, used coffee filters, shredded toilet paper tubes, or shred the box it comes in. This is how I will start mine.
Then if you want to, cover that with vermicompost that I guesse you will purchase. Generally that will cost you about $1.00-$3.00 a pound not including shipping. There is no such thing as 100% pure vermicompost, I still can't tell the difference between a coffee ground and a worm turd.
Next, add some kitchen scraps enough to cover the middle of the bag. 
Add some more of the VC to cover that and let that sit for a week. 
Pour water over that and have a pan or bucket underneath at all times.
Add a pound of red wigglers, thet cost about $35.00 a pound including shipping and only buy from a vendor that offers a live delivery guarantee.
Cover that with loose shredded bedding, like the rest of the box it came in.
Contact the seller about joining the facebook group and have fun.
I have been enjoying this hobby for a while and there is a learning curve. I have had a lot of fun and have made several friends world wide.
Yours Truly,
Mark from Kansas

**Q: where is this manufactured?**
A: Hi Margaret,
The Urban Worm Bag is manufactured in China and imported to the US. But never fear, I worked very closely with the engineers over there and they actually ensured that I ended up with an even higher quality product than I anticipated. Thanks for the question!

**Q: Question for the seller- would the worms do ok in a non-air-conditioned Florida garage? It gets very hot. Thanks!**
A: I live in Sacramento CA our Summers are 100+ with about 1-2 weeks out of the summer hitting 110-115. My Worm bag performed great throughout the summer. I suspect it is due to the size of the bag, and the temperature is cooler towards the center of the bag contents(My bag is nearly full). I believe you may have problems if your bag is mostly empty, or you're just starting, as there isn't as much of a temperature gradient for the worms to escape the heat. To combat this on the super hot days, Put a couple of 2-liter bottles of water in the freezer and put them on top of the castings on the hottest part of the day. But if you have a large quantity of castings already, you should be fine as the worms will migrate to cooler sections of the bag.

**Q: How do you harvest the worm tea from this kit ?**
A: You harvest worm castings from a worm bin, not tea. However, you can make tea from the castings if you want. The castings are harvested from the bottom, where a smaller section opens with a zipper. Once the worms have composted the food and bedding sufficiently, they should be working in the upper layers with the finished compost at the bottom. Unzip and remove, leaving the worms and newer food/bedding above. A worm bin needs to be moist but not wet.

### ⭐⭐⭐⭐ Latest Version Works Well (Updated)
*by B***H on February 9, 2019*

After my problems with the first version, the company quickly replaced my bag (excellent customer service) and I've been very pleased with the latest version (the 3.0, I think). Pros: *Sturdy stand (MUCH better than the original) *Very heavy duty bag material *Very roomy (I started the bin off with an existing 8 quart worm bin with about 2 pounds of worms and it just barely filled up the bottom couple inches) *The harvest panel is easy to access (the stand is about two inches taller than the original) and the liner keeps castings from getting in the zipper *The lid zips tightly and the double zippers make opening and closing easy Cons: None so far. The latest version is a huge improvement over the original, and the stand is nice and sturdy to hold the weight of the bag (I have it placed on a concrete floor and it does not wiggle when you zip and unzip the bag). The worms seem happy and, just like the previous version, there is tons of room for them to grow and multiply (the system can handle a LOT of worms!). Overall, with the new improvements I can definitely say that I recommend this sturdy, roomy, and well-designed new version for those who want to process a larger quantity of material. Original Review (Version 1.0): I’ve had my Urban Worm Bag version 1 for about six months now and I’ve harvested it twice. I had high hopes for this which were sadly not realized. Pros: * The construction of the bag itself is good and the bag is nice and sturdy and hangs from the frame evenly. * The top panel is easy to open and close which makes feeding easy and fast. * The surface area is great and provides lots of space for thousands of worms which process a lot of food scraps. Cons: * The construction of the frame is just plain cheap. Really, it was wobbly when I put it together and has only gotten worse as the bag has gotten more full and heavier. It has a distinct tilt to it now which is incredibly frustrating and disappointing. * Harvesting is a chore. It is very difficult to get the zipper open to harvest, and once it is open, harvesting requires crawling around on the floor to get your arm up in the bottom and get the castings out. Also, the space between the bottom of the bag and the floor is very small (less than six inches) so it’s hard to find a receptacle to harvest the castings into (I ended up purchasing a shallow litterbox to use for just this purpose). Also, due to the cheapness of the frame and its instability, you need to hold the top of the frame with one hand while you are trying to harvest out the bottom with the other which is not pleasant. Also, getting the harvest panel zipped again after harvest is nearly impossible. Overall, I have several other systems (storage bins, Worm Factor 360, etc.) and have kept worms for several years now and this is the only system I have so many problems with. It’s just not sturdy, and harvesting is a giant pain. This may be okay if you are are an experienced worm keeper AND are willing to upgrade the frame yourself, but for new worm keepers or those without the DIY skills necessary to alter the frame, I really cannot recommend this. Note: There is now a new version which supposedly has a different frame and harvest panel configuration, but I was not lucky enough to get one of those new models when I ordered.
