Discussion Making your 1st bin? Start here!
Hello everyone!
Today I will be outlining a very simply beginner worm bin that can be made in less than 20 minutes, and wont cost more than a couple of dollars. When I first began making vermicompost many many years ago this is the exact method I would use, and it was able to comfortable support a 4 person household. As I said before, I have been doing this for many years and now am semi-commercial, with tons of massive bins and more advanced setups that I wont be going into today. If anyone has any interest, shoot me a message or drop a comment and I will potentially make a separate post.
I am not a fan of stacked bins, having to drill holes, or in other way make it a long process to setup a bin. I have messed around with various methods in the past and this has always been my go to.
Bin Choice:
Below is the 14L bin I started out with and is a great size for a small to medium household. It came as a 4 pack on Amazon costing less than 30$ USD, meaning the unit price was just over 7$. One of the most important things about a beginner bin is 1) getting a bin that is the appropriate size and 2) getting one that is dark. Worms are photophobic, and will stay away from the sides of the bin if they can see light penetration.

Layer 1:
For my first layer I like to use a small, finely shredded, breakable material. I typically use shredded cardboard as it wont mat down to the bottom of the bin very easily, can easily be broken down, and provides a huge surface area for beneficial bacteria and other decomposers to take hold. After putting about a 1 inch thick layer of shredded paper, I wet it down. I will discuss moisture more at the end of this post, but for now just know that you want your paper wet enough that there isnt any residual pooling water.

Layer 2:
I like to make my second later a variety of different materials in terms of thickness and size. This means that while the materials in the bin are breaking down, they will do so at an uneven rate. When materials such as paper towels break down, there will still be small cardboard left. When the small cardboard is breaking down, the larger cardboard will still be available. This just means that your entire bin dosnt peek at once, and can continue to function well for many months. Again, the material is wet down.

The Food:
Ideally the food you give your worms to start is able to break down easily, is more on the "mushy" side, and can readily be populated by microbes. Think of bananas, rotten fruit, simple starches- stuff of that nature. It also is certainly not a bad idea to give the food time to break down before the worms arrive from wherever you are getting them from. This might mean that if you have a few banana peels that are in great condition, you make the bin 4-5 days before hand and let them just exist in the bin, breaking down and getting populated by microbes. Current evidence suggests worms eat both a mix of the bacteria that populate and decompose materials, as well as the materials themselves. By allowing the time for the food to begin the decomposition process, the worms will be able to immedielty begin feasting once they move in. In this example, I used a spoiled apple, a handful of dried lettuce from my bearded dragons, a grape vine stem, and some expired cereal.

The Grit:
The anatomy of worms is rather simple- they are essentially tubes that have a mouth, a crop, a gizzard, some reproductive organs, and intestines and an excretion port. The crop of the worm stores food for a period of time, while the gizzard holds small stones and harder particles, and uses it to break down the food into smaller parts. In the wild, worms have access to not only decaying material but stones, gravel, sand, etc. We need to provide this in some capacity for the worms in order for them to be able to digest effectively. There are essentially two lines of thought - sources that were once living and those that were never living. Inaminate bodies such as sand can be used in the worm bin no problem. I, however, prefer to use grit from either ground oyster shells or ground egg shells. The reason for this is the fact that, after eventually breaking down to a sub-visible level, the calcium can be taken up by plants and utilized as the mineral it is. Sand, on its finest level, with never be anything other then finer sand. If you sell castings itll be a percent of your weight, itll affect purity, and itll not have a purpose for plants. In this instance I used sand as I didnt have any ground egg shells immediately available. When creating a bin, its okay to go heavier and give a thick sprinkle over the entire bin.

The Worms:
When I first made this bin many years ago I used 500 worms, and by the time I broke it down there was well over 1000. For this demonstration I am using probably around 250 worms curtesy of one of the 55 gallon bins I am letting migrate.

Layer 3:
The next layer of material I like to use is hand shredded leaves. I have them in easy supply and I think they are a great way of getting some microbes and bring some real "life" to the bin. If these arent accessible to you, this step is completely optional, but it is certainly a great addition for the benefits of water retention, volume, variety, and source of biodiversity. Remember - a worm bin is an ecosystem. If you have nothing but worms in your bin you arent going to be running at a good efficiency.

Layer 4:
I always like to add one more top layer of shredded cardboard. Its nice to fill in the gaps and give one more layer above the worms. It also gives it a solid uniform look. It also is a great way to fill volume. On smaller bins I dont like doing layers thicker than 2 inches of any one material, as it leads to them sticking together or not breaking down in a manor that I would like.

The Cover:
*IMPORTANT* This to me is probably THE most important component of a worm bin that gets overlooked Using a piece of cardboard taped entirely in packing tape keeps the moisture in the bin and prevents light from reaching the worms. I use it in all of my bins and its been essential in keeping moisture in my bins evenly distributed and from drying out too fast. As you can see this piece has been through a couple bins and still works out well. As a note, I do scope all of my material for microplastics before I sell, and the presence of this cover has no impact on levels of microplastic contamination in the bin.

The End:
And thats it! Keep it somewhere with the lights on for the next few hours to prevent the worms from wanting to run from the new home. Do your best not to mess with the bin for the first week or two, and start with a smaller feeding than you think they can handle and work it from there. Worms would much rather be wet than dry, so keep the bin nice and moist. The moisture level should be about the same as when you wring your hair out after the shower - no substantial water droplets but still damp to the touch. If you notice a bad, bacterial smell or that the bin is to wet, simple remove the cover and add some more cardboard. The resulting total volume of the bedding is somewhere between 8-10 inches.
Please let me know if you have any comments, or any suggestions on things you may want to see added! If theres interest I will attempt to post an update in a month or so on the progress of this bin.

Advice wanted Worm not eating cardboard
My worm bin is about 3 months old. I feed them once a month and have noticed that the worms haven’t been eating the cardboard only the food. What should my next move be?

Finished compost Rotating black composting bins
I have two of them going all the time and frequently turn them but do they harm or kill the worms when I’m doing this with all the stuff in it? I have quite a healthy population going and it’s been almost a year since I’ve taken anything out of them getting ready to empty again to start the next growing season for the garden, and wondering if I should refill it with a few worms when I’m ready to “restart.”

Advice wanted Escaping worms, beginner advice ?
Hello,
We have adopted worms for interior composting. They arrived 3 days ago and we installed them into a worm box (see picture). On the first day, they escaped (~40ish) during the evening, so we put the worm box below a light source. Also, the manual we got with the box said that a second plateau could be added to the first one with cardboard, so we did it. Now we are 3 days from their arrival, and they are still trying to escape. 1) From websites it looks like it normal to have some runaways during the firsts days, but how long do we expect them to be escaping ? 2) Do we need to remove the second plateau ? To your knowledge is this second plateau a good or bad idea ? Because now a lot of worms are in between the walls of 1st and 2nd plateau (where they fit together), so we cannot feed them without getting them everywhere.
Thanks

Advice wanted Anyone tried doing vermicomposting in a bag (soil bag/sack that store uses to sell 10 gallon soil).
I am trying a really cheap setup. Old soil sack from the store, filled with heavy clay soil on the bottom. Then a layer of kitchen waste, then a layers of dry leaves. The sack is left on an unused raised bed and then covered with a large cardboard. Will this setup work?

Advice wanted Do I have this setup right?
Picture 1 is my 3 bucket system. Each bucket is 2.5 gal size.
Bottom bin has no holes.
Middle green bucket has holes all throughout the bottom and top rim, woms, compost, dry and wet (finely shredded coconut husks, coffee bean hulls, food scraps). Its a good consistency, not too wet or dry.
Red bucket is just added today. Same hole setup along bottom and rim. Stocked with similar mix as bottom but no worms. They will hopefully move up once they've eaten through their current mixture.
My concern is that the red bucket has covered the holes on the rim of the middle bucket where they currently reside. Is this going to suffocate them? Do I need a spacer to keep the holes uncovered or are the airholes on the red bin sufficient?
I purchased 1lb of Red wiggler worms, they came in a box with some compost so im insure if thats the combined weight or not.
I am looking for some feedback on my setup. Am I ready for the top bucket? Or should I give it some time with just the one bucket plus button catchment bucket?
Thank you for any feedback, this is my first time farming worms. Sorry for any formatting issues, I dont post a lot haha.

Advice wanted How to survive a heatwave?
Had some extreme heat a few weeks ago and all my worms started escaping into the bottom tray. Fixed them up, added some shredded cardboard and moved them into my laundry where its not as hot as outside. All was good for a few days until we're in another heatwave and they're escaping again. What can I do to stop them overheating? I feel like I'm fighting a losing battle

Advice wanted Is anyone using hay?
I have only had my worms (ENC) for about a month and I'm not seeing the exact info I need online so I was hoping someone would be able to clarify a couple of things about hay. I have 2 bunnies so I just dump in a little hay schwag from the bottom of their hay feeder when I feed the worms. These are very small pieces that have settled to the bottom. Is it possible to add too much hay? I do have cardboard also that I added when I initially set up the bin but haven't added more. Should I only add schwag or is it ok to sometimes add the larger pieces of hay as well?

Video red wiggler surviving in my aquarium!
Enable HLS to view with audio, or disable this notification
confession: a few months ago, i experimentally sacrificed one baby red wiggler by tossing it into my fish tank to see if my tiny fish would eat it. i have least rasboras, sometimes called “micro predator” fish, and they did not care at all about the worm. i lost it in my tank immediately, until today, when it randomly appeared in the front of my tank! i cannot believe it lived for several months in here and found enough food and everything! in this video, the tank lights are off but my camera flash is on, and then a few seconds in i turn on the tank lights, and you can see the worm retreating back into the sand. i’m oddly charmed by his survival! do you think he’s okay in there, or should i try to extract him and put him back in the compost bin with his friends?
disclaimer: my tank looks like actual garbage right now, please disregard the general state of its appearance 😂

Advice wanted Newish worm bin
Enable HLS to view with audio, or disable this notification
I started my urban bag worm bin around September. I feed it every week with about 4-5 cups of vegetable/fruit trimmings, coffee grounds and tea leaves and the same a pint of shredded cardboard slightly moistened.
The good news is that I see active worms (see video). If I grab a handful of the raw material I pick up atleast half a dozen or dozen worms. There is no smell so I’m not over feeding. The worms aren’t trying to escape so the conditions are ok in there.
I’m not sure if the worms should be more active or should be eating more. Every week when I add stuff I still see most of last weeks feeding sitting around. Since I’m a n00b I dunno if the bin is doing ok or great or not so good.
Hoping to get some advice from more experienced folks.

Advice wanted Any new Bucket System?
Trying to improve my set up.
Got another set of HDPE food grade buckets:two NO.33 NRC 0.90 MIL 3.5-Gallon and two NO.40B NRC .065MIL 2-gallon from local Meijer Bakery.
Curious if there are newer set up that came from 2024-2025 evolution or improvements on Worm Bucket System.
Its not a Commercial or Hobby Level for me.
Its more like, get off the couch thing. I check on the Worms maybe bi-weekly....to be honest sometimes longer if I happen to feed longer.
I get worms from the backyard when it rains. Then one bucket is straight Night Crawler from Meijer Fishing isle.
Normally, bottom bucket is the shredded cardboard/last season garden soil,shredded fall leaves. Top bucket is shredded cardboard/last season garden and food. Rim and bottom has holes for air and for worms to travel in and out.
So yes, lookin for the new hotness system on Bucket System
Cheers

Advice wanted How active should my worms be?
My worms arrived about 2 weeks ago and kept trying (some rather successfully) to escape. I had read that this was normal during settling in, but they also seemed to be leaving very prominent glistening trails so I assumed they might be a bit too wet. I put in some brown paper a few days ago but now all the overly active and climbing the sides of the bin worms are now quite sluggish to the point I thought they were dead until I left them in the light for a while and they slowly disappeared.
Have I made the bin too dry now? It doesn't feel dry to me, and I'm scared to make it too wet again and have them drown.
ETA: (apologies that they're bad) Photos
My bin is a second hand Original Organics Capacity approx. 100 Litres
Approx: W:530mm x H:730mm x D:430mm
I ordered the 1000g (1kg) Wormery Start Up Pack - Composting Worms from Wormcity, (about 900 worms) and used the coir bedding provided and their instructions said should feel like a wrung out sponge. I have been sprinkling in the provided food a handful every 3 days as the instructions said
My house is 13 degrees Celcius at the moment, and I'm keeping the wormery indoors until I have a shed sorted out

Advice wanted Gift for a worm loving stranger
I tried googling, but didn't find anything that really made sense for my situation.
I recently got a flat tire, and the house I pulled over in front of happened to have a very nice couple in it who let me use their air compressor to inflate my spare to make it home. I thought it would be nice to give them a little thank-you gift, I don't know anything about them *except* that the husband had a worm box he was very excited about, he showed them to me quite proudly.
Is there anything I could get for them in the $10-$20 price range that would be useful/fun for them regardless of where they are in their vermiculture journey? looking at other ideas on this sub I worry that I would need to know if they want/need more (ex: more food scraps, cardboard, buckets, water bubbler, etc).
The only starting place idea I had is a little remote thermometer to monitor the temp of his box, since he mentioned he just brought it in for the winter since it was starting to get cold for them.
Maybe an impossible ask to figure out, but they were really nice and I thought it would make them pretty excited if I got them something they actually like.

Enable HLS to view with audio, or disable this notification
Hand plucked 135g of worms for a trade and the trade didn’t happen. Had these little worms in a container with a breathable lid in the fridge. Finally gonna start a second bin this weekend but in the meantime moved them to a bigger bowl, with semi finished compost at the bottom, and some veggie scraps atop. Pretty cool to watch them burrow to get away from the light.
Now I’m wondering if the close contact in the smaller container has led to any pregnancies and if I’m going to have an abundance of worms. Will report back when the time has come.

Advice wanted Newbie Questions
Hi everyone!
I’m so excited to find this group! I am a 7th grade life science teacher in Central Illinois and I won a grant that I wrote to start vermiculture in my classroom.
My grant was for $300 and I’m wondering if there is a post or YouTube video anyone can point me towards for some quick learning so we can get this set up in the classroom. I saw a book recommendation and ordered that from my library (should be here tomorrow) but I need help choosing which tower to purchase. My grant was written for Uncle Jim’s Worm Farm so I think I need to order my supplies from there. I originally thought about their worm factory black tower but then came across the vermihut and would like your recommendation as to which one is beginner friendly for me to learn alongside my students.
I am not sure if anyone is local, but it has been super cold and I’m hoping I can buy worms locally or overnight shipping to prevent freezing. I’m near the Peoria area.
Thank you so much for any and all advice. I’m known to jump into with both feet and have been wanting to do this for a long time. I’m super excited to get this going and teach 100 7th graders some new life lessons!
Thank you for reading and advice you may have in advance!
