DIY worm castings

Hey farmers, I wanted to start a thread on how to make some of the magic happen in your organic dirt grows, with worms. I started my worm farm last year and it took a while to get my population up to where it could handle the waste from a family of four. I started with one# of purchased worms and I have over 10# now. That is a very rough conservative guess. I don't care enough to tighten up the estimate. These are the easiest animals to raise. I started with a rubbermaid 18gal bin and drilled a bunch of small holes in the bottom and sides. Just drill a bunch of holes let's not complicate this too much. You might think the worms will escape but they don't like the dry air outside the bin. Don't buy a bin. Recycle something that will hold at least a gallon of material. Anything opaque will do. 5 gal bucket. water heater tray, old hempy bag, reusable grocery bag,etc. anything that will hold some dirt like substance without drying out too fast. I live in the dry so I have to keep moisture in. If you live in the humid, an open container like a water heater pan is good. Don't use metal or toxic wood like ceder or redwood.

The first pic is my rubbermaid, The second is a water heater pan.
Once you decide on your container and have a bunch of holes drilled in it, you need bedding. Take some newsprint or recycled printer paper or whatever paper you can get for free and run it through a shredder. If you don't have one, borrow one. Stomp down some dried leaves, dried corn husks, any high carbon material. They like it broken down pretty fine but if you don't your worms won't bitch about it. Newspapers are only ok to use because of the colored ink. They don't like it and you will be picking globs of inky paper out of your bin when you harvest. Cardboard works really well if you cut it into pieces and soak it first. Fill your container about 2/3 full of bedding and wet it down until it's all moist but not dripping wet. Now you are ready for worms. Buy them online or get them from a garden center that has them. I hate to admit this but I haven't found a place to get free worms yet. If you have a compost pile in your yard you might be able to get red wigglers from the bottom of the pile. This is important: Earthworms will not work. European nightcrawlers and red wigglers are compost worms. They cannot live in dirt, and earthworms can't live in your bin. I would suggest having a few overripe avocados handy for their first meal. They love them and when they swarm all over the pit they will come into close contact to breed. You want them to be lovin' it up so you get more worms. If your worms can't find each other easily they will not multiply as quickly as they could. Worms are hermies. They breed in the 69 position and then "lay" a cocoon.

This cocoon will darken and in about 20 days 2-4 worms will crawl out.
Harvesting your worm castings.
I dump some or all of the rubbermaid onto the water heater pan and scoop the worm dirt into a pile. Do this outside on a sunny day or inside under strong light. Worms hate light so they will move to the center of the pile.

In the first picture I dumped a bunch of the worm dirt out of the bin and picked out all of the big chunks of food and bedding. in the second picture you can barely see the white bucket that I threw the worm dirt in. If you give the pan a shake the worm dirt falls to the side of the pile and the worms keep moving to the middle of the pile until you have this:

This is about 1/2# of wigglers. Imagine 1/2# of hamburger meat.
The 3 gallon white pail is half full of prime worm dirt and cocoons. If you want you can use this as is or if you are trying to populate, you need to get the cocoons out. Borrow, don't buy, a window screen and put the worm dirt on the screen. Let it dry out for a few days in the dark and sift the dirt through the screen. Or you can let it sit for 20-30 days until those cocoons hatch. Either way works. I sift. For those concerned with yield the picture of the bin was taken after I dumped the worm dirt/worms/cocoons onto the tray.
Feed your worms any vegetable stuff that isn't moldy. Some favorites other than avocado are, squash,eggplant, yams,and fan leaves if there is no spray on them. Some things they don't like are broccoli, cabbage, iceberg lettuce,(too wet). Try stuff that isn't obviously toxic. If they don't like it they wont eat it. Never put dog,cat,or people shit in the bin. Other shit can go in but take it easy and put some carbons(leaves, dry grass, shredded paper, cardboard)in with it. I will put my chicken litter in when I clean out the coop since it has benign(alder,maple) wood shavings and chicken shit. Remember no cedar or redwood or any tropical hardwoods. I don't think Black Locust would be a good choice either.
I think that's all I have now. Let the questioning begin.
If you are in the Vail/Eagle valley and want some worms to get started let me know.
 
Watch our with the chicken shit if it is too fresh it will be hot it is best to let it age. How long I do not know yet as I have not completed my search on all the info. I have read about this in several places but I have not asked how long to let it age nor asked any one how long to let it age. Horse and rabbit are also good with horse supposed to be the best. Check out a web site called red worm composting a lot of info on there.
 
Hey GD thanks for the input. I use this clay product called stall dry when the coop starts getting smelly and it locks up the N and slowly releases it. I would imagine that putting worms in straight chicken shit/litter would be bad but I don't do that. as you can see my worms are doing really well. That pile made about 1.5 Gal. of castings. I don't know exactly what worm castings cost but I remember sticker shock when I saw them at the hydro store.
 
Great info, thanks. I have a compost pile, a rotating bin and an 18-gal worm bin in a Rubbermaid tub just like you described, and the worm castings are the shit (no pun intended). You can find free worms at a horse stable in the manure pile if you don't mind what you have to go through to get them. Night crawlers (the American type, "regular" earthworms) don't care for horse shit, so you don't have to worry about any of them being in there. I've also read you can lay a large piece of wet cardboard on your grass overnight and there should be compost worms on the underside in the morning, but that's never worked for me. Also, if you don't care to sift through the castings and pick out worms when your bin is done, put a sheet of wet cardboard on top and then put a second bin with fresh bedding on top of that. The worms will eventually migrate up within a couple weeks, give it a month or so if you want all the babies out. You can also move all the castings to one side of your bin and put fresh bedding in the other side, and the worms will migrate over within a couple weeks. Then you can harvest the castings in the finished side. I don't have the problems with colored newsprint that you described, but I made sure my local paper used soy based ink before I used it as bedding, maybe that has something to do with it. You don't want to use the glossy-type newsprint that they print ads on, but I've had no problems with the regular stuff. Also, don't worry about the printing on shredded cardboard, soy-based ink is mandated by the government on all corrugated cardboard (but don't use cardboard with sticker-type labels on it). My worms definitely prefer shredded cardboard over newspaper.

Do you have a good way to store your castings if you don't want to use them right away?

Take it easy,

SL

Nice thread, I'm trying to do some worm composting myself but for free (or almost). Do you guys know if there is any way to tell which kind of worm you have just by looking at them ? coz I've got some but I don't know what they are.
 
If you got them digging up your outdoor garden they won't work. If you just had to collect them from your compost pile they will work. I have 3 Grape Ape seeds started and I'm going to grow one out entirely on converted worm food. I'll post pics of the "Vermipot" when It's time to transplant my seedlings. They're only 1 1/2" tall right now.

you can buy red wigglers at any pet shop as well as bait shops also sell them as "troutworms". They cost about 3$ for a few dozen worms. That's were I got mine from.
 
As Ace said that if you dug them out of the yard no good check out you local garden center craigs list garden clubs also if you could find somebody with horses you can find them in their piles of horse stuff.

Thanks Dbozz :) I went to the bait shop and got some, I was told that there were about 12 in the box but when I got home I counted them and I've got 21. I'm quite positive that they are red wigglers (the 3 woms I had before weren't).

I also got around 15 cocoons and I read that in 3-4 weeks they should hatch and that should give me another 45 of them at least.

So far so good, lets see if now I can keep them alive and happy and the family grows :)
 
If I remember right after the cocoons hatch it takes about 90 day to become breeders you get 2 to 4 per cocoon their is all kinds of info on you tube check out the web site red worm composting the guy who runs it will answer all of you questions alot of the members are willing to help out also..

Since you're starting with a small population, don't give them too much room or they will have a hard time finding each other to mate. no more than a gallon in your case. Really to have this work you should start off with a lb or more of worms. That is about 2000 worms.

Buy them online if you cant get them direct, but buy them in bulk. If you don't you will spend a fortune and it will take a really long time to get your population to a significant level.

Thanks for the advice guys, I don't really have any space/time for a big setup right now and I'm not looking to get worm humus yet, but I want to start taking care of some worms just to see how they reproduce and get to know them a little, I hope this will give me some knowledge for my future real worm farm :) So if I manage to keep them alive and increase their numbers I'll more than happy.

I do have them in a small container which is about 0.5 gallon and I have the cocoons in another smaller container so I can see when they hatch.

can a wormbin be left outdoors during the winter?no snow here but will dip to freezing every once in a while.
 
It depends on the size of the bin and how many worms you have, from what I have read online if your bedding is deep enough and they can keep from freezing you should be alright. Go to redworm composting and ask Bently he lives in Canda and gets snow and has some of his bins outside and also does windrows outsid and has a ton of worms.
 
Hey kids I wanted to post up after a while. This bin needed split badly as it was overpopulated. I couldn't take pics while I was working but I will put up pics of the final product. Final results since Oct., +/- 4 gals of castings+cocoons and 10#+ on worms. All of the unfinished vermi and worms were divided into four bins of half finished compost. I use Cap's Bennies so now I have four gallons of good stuff to use for ACT. I am going to sift most of what I have one more time to rescue my cocoons before I use it.

The white bucket is a 6 gal the pic makes it look half full but it has over 4 gals of castings/cocoons. The green bin is now half full of worms, bedding, and food and whatever castings didn't get collected. I used three of the black plastic planter pots 2 of which are shown. Those have fresh 1/2 cooked compost, fresh used chicken litter and about 2# of worms. I don't know how that porn got there really.
