Worm bins need not be expensive or hard to build.
We are going to show you how to build a great worm bin to house your composting worms.
The above-pictured worm bin cost about $11.00. The dimensions of this bin are 14 x 18 x 6 inches deep.
The lid also features a rubber seal making it virtually escape-proof.
These worm bins give you 1.75 square feet of space which will handle two pounds of redworms easily.
Worm Bin Inhabitants
We do not want to start with 2 pounds of worms of course.
We would suggest adding a half pound to one pound of worms to start.
If you are a new redworm grower, our suggestion would be to obtain a starter worm bin mix that contains worms of various sizes, cocoons, and worm bedding materials.
The bedding material is from an existing worm bin and will help to inoculate your new bin with beneficial bacteria and fungi.
Young worms and cocoons also seem to adapt more easily to a changed environment. Let’s get building our new worm bins.
Worm Bins Are Easy To Build
We need to purchase a Ziploc WeatherShield box in black (not the clear one). Our local Walmart stocks these for $10.73. You can also order online from Walmart if not available locally.
The tools required are a drill, 1/4 inch drill bit, and a jigsaw.
The tape points to the corners to be drilled.
We want to drill the lid with the 1/4 inch bit in the four corners as shown. This allows us clearance to get our jigsaw blade into the lid.
We then cut out the center of the lid as shown. Be sure to leave the first support rib all the way around so the lid still has structural integrity.
Congratulations…. you are done. Clean the box up by washing with soap and water and rinse well.
Fill with new bedding to about four inches deep.
I made a Youtube video showing how I cut the center out of the lid:
We now have a very reasonably priced, escape-proof worm bin that will hold at least two pounds of redworms.
We need black bins because they are opaque and worms do not like the light.
These bins can also be stacked up to three high if you put stickers ( wood pieces that span across the cut-out opening) on the tops.
There needs to be airspace so the worms and bedding get good air circulation.
We do not drill drainage holes in the bottom. You certainly can if that makes you happy.
There should not be leachate running from the bottom if you are checking your moisture levels regularly.
The foam seal is nice to prevent mass escapes when conditions are not right in your bin.
If your worms are happy, they will not even try to escape.
Make one of these bins and try it out for yourself. Worm on.
