[Strawbale] Sign me, up, dude

[Denise Ohio]

Mark,

We live in a marine climate (Western Washington, USA) and are building a 
loadbearing SB house next year.

We'd planned on tracking wall moisture levels using the Habib sensors (he's 
going to help with out bale and stucco work), and would certainly consider 
running both sets of sensors for comparison. Tracking isn't that hard (we 
were going to do it anyway) and I could set up an Excel file or even a 
plain old notebook to scribble the numbers.

We'd need standard procedures, including calibration and suggested placement.

How do we get started on this?
