A few months ago I started reading about vermicomposting and really wanted to try it. Growing up my parents always had a compost pile (actually three bins in rotation) in our back yard. My mom has a picture on her blog. (Yes my mom has a blog, yes I helped her set it up, yes she did a multi week series of pictures of manhole covers, yes we have suggested she needed psychiatric help, and no she did not go.)
In Anchorage it is mostly too cold to compost (something about the piles freezing and the chemical process stopping). Plus I’m betting that our condo association/home owners group has a rule against compost bins. But I hate throwing away veggie and fruit scraps. So vermicomposting seemed like the perfect solution. It can be done indoors in smaller quantities, supposedly doesn’t smell, and it has a cool name that doesn’t at all sound weird. Vermicomposting is cool, modern, and eco friendly. Worm farm is weird and hippy.
I am weird and a hippy (as I am discovering more and more), but I’d like to put prettier labels on it when I can. And thus a couple of weeks ago, I started my worm farm/vermicomposting adventure.
There are lots of instructions and ways to go about setting up your warm farm. You can even buy a fancy, expensive worm factory 360. Or you can do what we did and find some instructions online and go the DIY route. There are a ton of instructions online, but we chose this one because like the expensive pre-made option, the worms can crawl from one level to another gradually over time.
Oh, did I say we? This became a group project. I got my hippie enabler friend Hilary (some day our husbands are going to stop letting us talk to each other, we feed off each other too much) and her housemate Sarah to go along with this. Or I was tagging along with them. Whatever. Group project time!
First we drove up to Eagle River to buy worms. We bought a bags of worms from the Worms and Stuff lady. She was fascinating to talk to and a great source of information. Her website is really helpful too. She sells the fancy expensive worm factories and has instructions on how to make a different version. Plus she confirmed that the worm factories don’t at all smell. Admittedly that was one of our biggest fears since we were keeping things in our house. (In the garage it gets too cold, not cold enough to kill the worms, but cold enough they go into near hibernation and aren’t actively chewing up food scraps.)
While at the worm lady’s house, we could feel the worm bins and see what the actual appropriate moisture level is. (Too moist and the worms drown, not moist enough and the worms can’t breathe through their skin.) You’re aiming for just wrung out sponge. Her worms are also sold in Anchorage at Alaska Mill and Feed.
After the worms were acquired, everything else was purchased at Home Depot. Two rubbermaid 10 gallon tubs and a broken paving stone each. We convinced the Home Depot guys that because they couldn’t sell the broken paving stone and they would just have to throw it away, to sell it to us for a great discount.
David was gone for the weekend (hunting) but left behind a drill for me. This involves one size of drill holes in the bottom and another on the sides and the lids.
After marking off the bins, we took turns drilling. All told it was probably ~100 holes per bins, four bins total.
We burned through two batteries and I had to wait to drill the last 30 or so holes until the battery recharged. I showed David what I had done and he told me if he had realized how much I would be drilling he would have left me the 20 volt drill instead of the 12.
Yeah, apparently he thinks my projects are little and cute. Oh well. To be fair I did have to have a quick refresher course on how to use the drill.
After all the holes are drilled you need to shred up a lot of bedding. I meant to bring home shredded paper from work, but forgot. Instead I hand shredded newspaper which probably is safer for the worms. Some people on the internet are very concerned about the dyes used in ink cartridges. Or something. Whatever, it is all recycling.
Take the lid that doesn’t have holes in it, put your broken paving stones on top. This will create a drainage area if it gets too wet.
And we are going to do the rest of this photo essay style. You really should read the linked instructions above for a full instruction.
Fill the bottom with your newspaper, wet it down with a spray bottle, and add in your bag of worms (that have some shredded paper and dirt already).
I used the box from our full circle organic produce delivery, which is supposedly super compostable, to put on top of the worms before the second tub. It creates a barrier for smells and to keep the worms from exploring too much. Eventually they’ll eat through it, but that will be time for them to move on anyway.
And I’ve been doing this now for about two weeks. They love our coffee grounds and it isn’t smelly at all. The trick is to never add in meats or animal products (except egg shells that are first baked in the oven) and thus avoid smells. The egg shells balance the ph of the system, baking them keeps it from getting that rotting smell. Yay composting! It just feels so good to not throw away veggie scraps and coffee grounds. Next up on the hippie agenda, garden boxes and an update into my natural hair care path.
