How to Build Your Own Worm Bin

When we started our worm farm, we had the experience of both purchasing a worm bin as well as making our own bins with products from a home improvement store. Our suggestion is this: if you're looking for the convenience of a ready bin, you can purchase from numerous sources. If you're looking to save money, then you can easily make your own! It may seem daunting at first but, I promise you, it's well worth the effort. 

 

List of materials:

  • 2 stackable containers (size of your choice)
  • 1 lid
  • 1 electric drill 
  • 9/64mm drill bit
  • 1/16mm drill bit
  • red wiggler worms
  • coconut coir

In one of the stackable containers, drill as many 9/64mm holes as possible on the bottom of the container.  

(Note: Although I specified the size of the holes, your goal is just to drill a big enough hole for a worm to be able to wiggle through, but not so big that all your bedding material falls through.  The purpose of the holes is also to allow the excess liquid, called "leachate," to drain through to the bottom bin.  Simply empty the leachate about once a week.  The leachate is nutritious for plants so you can just pour it over your plants.)

 

Within the bin with the holes drilled at the bottom, spread a layer of hydrated coconut coir.  Amount of coconut coir depends on the size of your bin and the number of worms you have.  Then stack the bin with the holes onto the other bin without the holes.

 

Now, lay the worms on top of your coconut coir, then cover your new worm buddies with a comfortable amount of coconut coir.  

 

Once you've completed those steps, drill a few holes with your 1/16mm drill bit on top of your lid so the worms can get some air. 

(Note: Again, it's your choice on the size of your drill bit.  The goal is to have holes small enough that insects or other parasites cannot access your new pets, so the smaller the hole, the better.)

Pop that lid on and you've completed your very own vermicompost worm bin!

 

While your worms get acclimated to their new environment, they can subsist on the coconut coir for a few days to a week.  However, after that period of time, we recommend you begin adding a variety of food to your bin.  Check out our blog post "What to Feed Your Worms" for more information.
