We used to run the traditional element-in-barrel sterilize design, until we had the water supply shut off unexpectedly. It steamed dry and the element started a fire in the substrate🔥🔥🔥🔥🚒 

We wasted hundreds of dollars on our first mushroom sterilizer, only to burn it to pieces. A
fter that we switched to an external mushroom steam generator and never looked back! 😊😊

This steam generator is connected to a barrel or tank, and used to steam mushroom substrate until it's semi sterilized or pasteurized. 

Benefits of our steam boiler are: 

  • Can use any size element 👈 
  • Can switch between sterilizing vessels 👈
  • Very fast heat up time 👈
  • Sturdy construction 👈
  • Much safer than the traditional element-in-barrel design 👈
  • Will not rust 👈
  • Extremely energy efficient when insulated 👈

Designed in house at Oak and Spore. These blueprints can be taken to a local stainless fabricator and constructed. 

We have included a low water shutoff switch on ours. The hole for this is not on the plans as you might use a different dimension shutoff switch. The hole can easily be drilled where it's needed.

This blueprint is FREE when you purchase our online farm profitability course

The file is a PDF with all dimensions and measurements on it. 
You get an additional excel file with the the parts and links to purchase them.

We ship all items as fast as we can. Some products might incur a slight delay as we ensure the mycelium is happy, healthy, and fully colonized.

Awesome little plans, It was a pleasure doing business with Oak & Spore, every thing went as it should, & am more than happy with the plans. I am looking forward to getting it all together & am already seeing other applications how & where I can use it. Thanks again for putting it out there for folks to purchase.

Yes! All the hard work has been done. The mycelium is fully colonised, and they are ready to grow some tasty mushrooms!

Generally between 1-2 weeks to get your first crop. They grow very quickly!

Generally one or two flushes from a boxed farm, two or three from a commercial farm. There is about a 1-2 week rest period between flushes where the mycelium will just sit and relax for a bit.

No! Oyster mushrooms actually like some indirect sunlight. So nearby a window is fine, as long as the sun doesn't beam onto them.

The bathroom or kitchen is a great spot for a few reasons. You are often in these areas, so it reminds you to spray them with water. Mushrooms like fresh air, and you often have a window slightly ajar. Mushrooms like indirect light, and these areas often get some sun. And finally, these areas have easy-to-clean surfaces, so you can wipe away any spores.

Growing some mushrooms to eat in your kitchen, bathroom, or laundry is fine. They will drop some spores if allowed to overgrow, but these can be wiped up with relative ease.
