Mycoinsulated Roof with Beau Davidson- Movie - HD streaming

Come out to this year's PTJ to do some more mycoinsulation, roundwood timberframe, and other natural building projects with me and a pile of other fine folks!

Beau, you mention wool insulation behind fabric/burlap as part of the 2024 PTJ - is there a specific reason you're looking to try something other than mycelium here?
What if you had Mycelium-based Structural Insulated Panels, do you think you could devise a way to affix them to the inside?
What if you had access to a bunch of cedar planks, would it be worth investigating cedar as an exterior for the Myco-SIPs, or are the fungi going to be too sad?
If you were attempting such an experiment, would you keep the method and use second flush bags cut to fit?


At T17:30 Beau talks about spreading these bags in hugels etc. - if any were spread on the berm in Near-Arrakis, I can confirm yellow oyster mushrooms fruited in late May 2024 :)

Per T40:16 & T40:21 it looks like the solar system is a 12 Volt 200 Amp DC system; further, at the second timecode, the object under the digital read out looks to be a fuse block or bus bar of sorts.

If that's the case, adding a circuit could be relatively straight forward with two light bulb socket bases.
There are 12V bulbs made by Bulbrite which are 25W and fit into traditional sockets, sold in a two pack for ~$3.
The thing I haven't figured out is the thermostat - I'm imagining there exists a 12v inline thermostat which could be wired onto the positive lead, but I've done very little searching and would love another perspective here.

No, just that I had the wool and burlap on hand already.  For the side-walls, I was thinking not mycelium in case of moisture - although that should be mitigated, so it shouldn't be a problem.

I do think that would be a viable path.

I do not expect most varieties of mycelium to adhere to cedar.  It might be possible to dessicate a mycelium panel and adhere or affix it to cedar cladding, but I would rather not.  I am more drawn to letting it do what it wants to do.

Why are you thinking cedar?  Rot resistance?  If rot is a concern, mycelium is probably not a great option.  If we're mitigating against rot, then cedar shouldn't be necessary.

If you were attempting such an experiment, would you keep the method and use second flush bags cut to fit?

I would prefer to grow SIPS in their final form, but yes, it could be possible to assemble infill from second-flush bags and let them grow together.

That's awesome!  Yup.  Any pictures?

I think we have a thread somewhere ideated solutions for this project.  Do you have access to the PTJ planning forum?

That totally makes sense, thanks!
My thought was more practical; I happen to have a few hundred 2-foot long 3/4 cedar fence slats and was thinking of other ways I could use them. It sounds like, on balance, they could be put to more effective use elsewhere.

Here are some pics of the event! I spied, Rebekah harvested, then did a spore print of these. After confirming, she cooked them splendidly and they were delicious :)

Watch the trailer!
