Do worm bins really need drainage holes?

One of the biggest concerns people have about using a single bin worm farming system without drainage holes is that there's nowhere for excess moisture to escape. And they're absolutely right!

That's why moisture management is so important.

In this video, I'm checking on my European Nightcrawler worm bin, which doesn't have any drainage holes, and showing you what happens when the bedding starts getting too wet, muddy, and swampy.

Instead of drilling holes in the bottom, I'm adding a generous amount of shredded cardboard to help absorb excess moisture, improve the bedding structure, and create more air spaces throughout the bin.

I'm also holding off on feeding for a few days to give everything time to balance out.

One of the things I love about worm farming is that there isn't just one way to do it. You can absolutely have a successful worm bin with drainage holes, but they're not necessarily required if you're willing to monitor and manage the conditions inside your bin.

The key is paying attention to your worms, checking moisture levels, adding dry bedding when needed, adding moisture when things get too dry, and making adjustments along the way.

Hopefully, this video helps you feel more confident managing moisture in your own worm farm, whether you use drainage holes or not!

Happy worm farming!
