In my last video on vermicomposting, I went through a simple setup of a single-tote worm bin from Uncle Jim’s Worm Farm. Pretty soon, that bin was full and it was time to redesign the system to be more scalable and easier to work with.

A 3-tote stackable system has a few advantages:

– Bottom tote can be used for drainage of worm juice
– Middle and top bins can be swapped out infinitely
– Worms will self-separate from castings, making harvesting castings easy
– Can hold way more food scraps and worms

Overall, a stackable system is simply better than a single-tote system. This video goes through exactly how to build one, with a few modifications that I made note of in the video. There are probably more ways to improve upon this design as well, so let me know in the comments. So far, it’s working wonderfully though!

Making a DIY worm bin adds a ton of extra fertility to your garden and is a great way to make use of food scraps 🙂

Building a Stackable DIY Worm Farm for $30 🐛

    I like your build however I think the holes should be a little bit bigger so the worms dont have to be as accurate when migrating to upper trays.

    Do you have a link for your "friend Steve over at nature"? Couldn't hear what you said, couldn't find a link in the show notes.

    Will this cause roaches ? I had an outdoor one (first time) and I was too scarred of the bugs

    Can you share about indoors and bugs ?

    tech. they wont suffocate because the worms wont go towards danger. they will move towards a safer location. so no need to freak out. ive been keeping a 30gallon tote just like the one you showed in the beginning and there is no drainage holes or anything and all the worms i put in there are all still alive reason being ive counted all them in the bin. the bin has been set up for just about a month now and doing very well. i know i know there will be people hating or have their own opinions but ive never had a prob. and oh ive enen done it with a single 5gallon bucket and with that i have done drainage holes and found no difference except for more aeration.

    Where did you buy your totes at, I looked at Walmart, amazon, home depot and they all sell for about $ 40.00 EACH !!! PLEASE HELP, I can't afford them for $ 40.00 each.

    How do the worms get up to next bin? Is the top bin on top of compost? Or is there space between Co post and to bin? Thanks

    You don't need a spigot. Just a flush hole with some sort of container beneath to catch the liquid. Obviously, the bin will need to be raised for clearance of the container that catches the liquid! Just my two cents….

    I watching this after trying to do a two story worm bin where we were dumping about 15 lbs a week in food waste. …so granted, mine was quite a big larger than a typical single person would produce and it filled the whole bin within a month. A problem I encountered was that the weight of the bins on top seemed to have compressed the materials below. This caused some drainage problems for me. Solution: add spacers to keep the weight of the top bins from directly compressing the lower bins.
