Building a Laminar Flow Hood for Mushroom Cultivation

If you’ve ever tried growing mushrooms, you know about the challenges that maintaining sterility can present. Laminar flow hoods are the gold standard for creating a sterile workspace for mycology, and can make the work so much easier and more enjoyable. In this video, I’m going through how I built a high quality laminar flow hood for a fraction of the price of buying one. I’ll explain my thought process as I was designing it, go over how to choose which components to use, and share some general tips and considerations.

Doing a build like this can save you tons of money and leave you with a result that’s as good or better than anything you’d purchase. You can also make your hood completely custom to fit your space and needs. It will require a decent amount of handiwork and tools, and probably took me a good 15 hours to design and another 15 to build (hopefully this video will save you time on the design stage). But if you’re like me and love a good project, doing something similar to this could be the right choice for you!

**Disclaimer: This isn’t technically a flow hood since there’s no hood component, but the term is widely used in mycology to refer to this kind of laminar flow filter box, so I’ll be using it throughout the video.
