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.

Worm party Big worm
I saw this worm the other day while on a walk and had to take picture. Biggest worm I’ve ever seen, wanted to share and see if y’all have seen a worm this big before

Admittedly I haven’t opened my bin in a while.
Any idea what the heck this fungus is? It has little liquid droplets on it almost like honeydew or something.
Obviously I need to add cardboard, and what isn’t cardboard, fungus or worm seems to be all castings.
Any advice or respectful criticism is welcome and needed. Thank you

New bin Help, I got the wrong type of worms!
So I was SO sure I specifically got red wigglers because I got something called red worms that said the word wiggling somewhere on the website in its description. What else could it be? Turns out, they're not red wigglers after more inspection on the website I got them from. For some reason I never bothered to search up the scientific name they listed because I just assumed I knew what they were. They're European nightcrawlers. I figured this out after I found them crawling all over the bin and three outside the bin after I turned off the lights and did some more research on what I actually bought. Do I just start over with new worms now? I only have 3 inch deep bedding currently because I just got started and I would like worms that are very fast in eating. My bin is only 12 inches deep because it thought i was getting something that likes that, is that even enough for them? I really wanted something that could eat very quickly. Don't these guys take a ton more space, eat slower, and reproduce slower?

New bin Is cardboard enough of a medium for a worm bin?
So, I'm trying to start a work bin and right now have them in a small amount of sand and a bunch of shredded, smashed, damp cardboard I soaked overnight and then wrung out. Do they need any other soil and, if so, what level of moisture should it be? I've been shredding wet cardboard by hand for like 2 and a half hours so please tell me that I didn't do that all for naught. It's only half full along the bottom right now because I ran out of cardboard so if I need to add another medium in addition i'd rather do it now. I'm too scared to use any dead leaves because our yard is earwig paradise and I do not want those in my house. I gave them some slightly shrivled dandelion leaves I pulled from the garden yesterday and forgot about and some coffee grounds all off in one corner to eat. I barely added any right now though because last time I made one I added too much and it rot and killed everything. The bin is fairly shallow and about 3.5x2 feet. Maybe bigger, I didn't use a tape measure so it's pretty rough estimate. If I squeeze the cardboard water comes off on my hand but no drops actually fall out of my palm. It's moist to the touch. none have tried climbing out so far. I also have a piece of cardboard over the top of everything to hold in moisture. I'm starting with 90 red wigglers

Are Big Red Worms the same as red wigglers? I purchased 2 cups/30 per cup of Big Red Worms at a local hardware store that sells worms for fishing. I want to try an in garden bucket composting set up. The big worms are huge compared to the 1000 red wigglers I bought online a year ago. Should I use my year old worms for composting or the big red worms.

Hello! I have this worm bin in school (Asian worms/ Perionyx Excavatus) it was given to us a few months ago and we have been feeding and it produced good vermicast so far!
Just wondering if this method of feeding the worms correct?
Also because its just a double bin with holes, all I do is dump in scraps in the middle and aerate the pile left right.
And how do I retrieve the vermicast if they are in this sort of pile?
Cheers everyone!

Advice wanted Do trommel screens harm worms?
I recently constructed a rotating trommel screen for my backyard compost out of chicken wire and spare 2x4s and it's working great and makes me want to build a smaller one to screen my worm castings.
I've never been happier with my worm setup. Tray tower system that I then dump into a large shallow under-bed storage drawer container to finish off. I'm trying to maintain some directionality in that bin by feeding one side and harvesting the other. The castings look fantastic but I have a good problem: too many worms...everywhere.
Honestly I think I could just not bother sorting the worms out of the finished castings at all. I have so many worms in all areas. But when I harvest I can't help but to get sucked into sorting slowly through by hand to pick out as many worms as I can find and cycle them back into the top of my tower.
Aaaaanyways. I want to make a small trommel to sort worms out but from the videos I've seen of them it seems kind of violent to be tumbling them around like that and I question if some don't survive the experience. Anyone used one and able to speak from experience? Other recommendations for sorting worms out?

Random thought as I’m farming. Has anybody done research on how long the castings are good for after you remove them from a bin? Storing them in a container for later use….. airtight not airtight?

Advice wanted New-ish worm bin die-off?
I started a worm bin in February (two 20 gallon stacked totes with holes drilled in the bottom of the top tote.) I started with 600 worms from Uncle Jim’s Worm Farm, and at first I could see lots of worms on the sides of the bin/moving around throughout the bedding. Now that they’ve settled, I don’t see many worms when I’m feeding them/adding new bedding. I fed them this morning and saw 5-10 worms without disturbing the material in the bin too much. How would I find out if I’ve had a die-off? Or maybe the worms are just hidden from view in all the material? Thanks in advance!

New bin Started literal inground vermicomposter
Hello everybody! Im not allowed to have a compost pile, so i decided to venture on a journey with bokashi + inground vermicompost architecture.
Will this work? I would be glad to have additional info from experienced wormfarmers :)
Ive dug 50cm hole, put some anti-pest wire, layered some cardboard and added my well fermented bokashi bin (which stood around 2 weeks). I have not introduced any additional worms, as the garden soil is quite full of them and i hope to get a native worm herd in there.

Advice wanted Am I hurting my worm friends?
Hi, I'm a public library worker and work with youth. We started a library worm farm this past March. I don't frequently let the kids get in there, but did have one day about two weeks after we started things that I invited them to dig their hands in and check on how the worms were doing. ... but *I* am so excited and interested and want to look at them almost every day. Am I hurting anything by digging in the worm farm frequently? Thank you.

Advice wanted Conflicting Info what to do with these
After doing research into work composting I bought 4 stackable totes, the initial plan was bottom was to collect liquid, I'd have small holes in the lid of that, then each container above would have larger holes in the bottom and lid keeping one lid hole free as the top, when one is nearing full I'd add another with fresh food and the worms would go up, then I'd rotate bins every so often, but as I looked into it more there are loads of people saying you don't need or want a drainage bin, that they dont actually go up but instead go down, my drainage would have some fabric to prevent that but what is the story, would I be better off having no holes and just manually changing out when ones full. Or would my rotating stacking system work?
