Introduction: Compost at Lightning Speed With a Bucket Worm Farm!
Using worms to eat your food scraps is a great way to make use of almost all of your food. Red wigglers seem to work the best since they're so active. One pound of worms can eat up to half a pound of food per day!
In this instructable I will show you how to create a slick looking worm bin which will fit under your kitchen sink.
QUICK UPDATE: After over a year, the dudes are still going strong! This design totally works great.
Step 1: Stuff You'll Need!
You will need
- 2 Buckets - They should be 5 gallon, but I've used 2 x 2.5-3 gallon buckets. I don't yet know if this will work with buckets this small. Check your local bakery for free ones that they're throwing away. I tried that but ended up having to buy a couple cheap plastic garbage cans.
- 1 Shopping Tote - This needs to be polyester because if it's cotton, the worms will eat through it.
- A newspaper and/or plain cardboard - A regular newspaper will do. Don't use the glossy type. Strip anything non cardboard (like tape) off the cardboard.
- Some water
- Some method of drilling or puncturing holes in the buckets - a drill, knife, hammer, force of will, etc.
- A small amount of leaves and grass clippings
- Worms - I'd start small with a half a pound (500 or so) and if you need more, get more after
Step 2: Drill Holes in the Buckets
Worms need air just like most other living creatures, so drill lots of holes in both buckets for ventilation.
I put both buckets together like they are going to sit when they're finished and drilled holes through both of them so that they would line up. The fit of the buckets was so tight on mine that I ended up folding some leftover cardboard paper and using it as a spacer between the buckets so that air could get to the inside holes.
Make sure you drill a few holes in the bottom of the inside bucket. This will allow water to drain out so your worms don't drown.
This is why you have two buckets. The bottom bucket catches the "worm juice" so you can use it on your plants to encourage microbial growth (this is a great thing!). I haven't tested this, but I'm thinking you could dilute the worm juice in a 5 gallon pale with water and aerate the mixture with an aquarium pump and a tablespoon of molasses to create a type of compost tea. If you try this, please let me know how it goes. If you want to qualify your results, set one plant aside to try this on so you can see the difference in results. Remember, compost tea's results are most noticeable in unhealthy soils.
Step 3: Sacrifice One of Your Grocery Totes
Take a fabric grocery tote and put it in the bucket. I took the handles of mine, wrapped them around to the bottom of the inside bucket and secured them with parachord so the bag wouldn't move. Feel free to use whatever means you wish to secure the bag.
The bedding and worms and "canopy" (for lack of a better word at the moment) will go inside the bag. The bag allows water to drain out freely and air to get in, while keeping all the castings and bedding and compost contained.
Make sure the bag is made out of polyester! If it's made of cotton, the worms will eat through it. This wouldn't be the disaster of a lifetime, but it would potentially make more of a mess than you want.
Step 4: Time to Tear Some Paper!
Find your least favorite newspaper articles and adverts and shred them into small pieces. Soak the paper in water for a minute or so and add them to the bottom of the bag. Shake off any excess water. This will serve as the bedding for the worms.
I'm sure you may be wondering about the newspaper print being bad for the worms as I did, however when I googled this, I found out that most newspapers use soy ink. This doesn't include paper with shiny surfaces. I'm talking about your typical newspaper...paper.
Feel free to read for yourself here, or google for yourself. I'm not going to claim I know everything on this topic. I'm only sharing what I'm doing and the research I did.
Step 5: Add Your Worms
I picked up my worms from this nice lady. She's more expensive than a lot of places, but she's local and fairly close to me, so I know my worms won't die in transit. She's also very helpful.
The worms came in a bag with bedding and soil, so I just had to gently dump the bag into the compost bin bag.
Step 6: Cover the Top
In order to give my worms a forest floor feel, I went outside my apartment and found the first pile of leaves laying around which happened to be on a lawn next door. While my wife and I were grabbing some leaves a lady who lives in the house came over and asked what we were doing. We felt kind of awkward, but we explained about the worm farm and had a really good conversation with her about her garden and compost. She was happy to let us take some leaves.
Place the leaves on top of the worms to give them a nice homey canopy.
Step 7: You're Done!
Now place your lid on top of your buckets and put them wherever you wish...well sort of. Keep them at room temp.
Place your finely chopped or blended veggie scraps, coffee grounds, tea leaves etc under the leaves and watch them disappear. Well that would be boring. Just put the lid on after and trust they're disappearing.
A few notes:
What to feed your worms:
Fruit scraps and peels (mold/rot is fine)
Bread and grains
Coffee grounds (and filters)
Crushed egg shells
Napkins, paper towels
What not to feed your worms:
Don't overfeed citrus (no more than 1/5 of worm food. I don't feed my worms any citrus)
Twigs and branches
Dog/cat feces, cat litter
Keep an eye on the worms health and make sure they're doing okay. I usually judge that by how wiggly and energetic they are. Research worm farms for yourself and make changes if you need to.
Please share any ideas you have or edits you've made.

Step 8: Update
I just wanted to post an update. After 5 months, I've harvested compost twice and the worms are still going strong!
My wife and I went on our honeymoon for two weeks so we fed the dudes quite a bit of scraps, and they were still striving better than ever when we got back.
Major success! Very happy with the project.
