Hi Terry,
Thank you very much for this valuable information. So based on your logic I should experience no difficulties using einkorn wheat. Actually I plan to use it for both straw-clay and cob, together with oat straw, which in particular is described as suitable for cob in Ianto's book.
Another topic I'm stil not sure about is the "maximum" width of straw-clay wall which is "safe" to build. Safe in terms of moisture. Although I'm planning to build the wall in the hottest part of the year, when usually even night temperatures don't drop under 20 degrees C (and day temps are often above 28-30 C), I was told by some experienced earth builders it's risky to build straw-clay wall wider than 15cm. My wish, however is at least 17 or even 20+ cm. Does anybody have practical experience in such widths? According to the video, it seems to be ok, but still?
Thanks for the help!
