I now have not one, but two mini-vermicomposting bins ready to house worms!
After my initial failed attempt to construct a small worm bin from some clear Sterilite containers, I took a trip to my local OSH and found the small Rubbermaid Roughneck tubs I was looking for. They were relatively pricey ($5.99 each for the 3-gallon size, while the huge 18-gallon size was only $8.99), but they were the perfect dimensions (16"L x 10.75"W x 7"H), and opaque as well.
I picked up three tubs and lids - the worm bin only needs one lid, but I got spares in case I messed up while drilling again! The Rubbermaid material is soft and easy to drill. I successfully made 1/4" holes in the bottom of two tubs (the third has no holes, as it goes on the bottom to collect liquids), and 1/8" holes on the sides and lid.
My new worm bin fits perfectly under the kitchen sink. I filled the top layer with shredded newspaper - and now I'm ready to bring in some worms!
As I mentioned at the beginning of the post, I actually have two homemade worm bins now. My mother read my recent blog post about how the Sterilite containers I initially bought to construct the bins cracked while I was drilling them. I hadn't thrown them out yet, and she encouraged me to just patch them up with duct tape.
Moms do know best! I bandaged the more broken tub, and carefully finished drilling holes. The sides and lid were actually pretty easy to drill - it's the bottoms of the tubs that were the most brittle.
I would still recommend going for opaque Rubbermaid Roughneck containers instead of clear Sterilite tubs if you have the choice. The Roughnecks are a lot easier to drill, plus the opaque material will protect the worms from light, so if you wish, you can store your worm bin somewhere out in the open rather than under the sink.
I know I'll be able to make use of both bins. Maybe I'll put some worms in each and see if I notice any difference between how they perform!
