[Cob] Late season cobbing (The experimental greenhouse)

[Henry Raduazo]

	I was wondering if anyone has ever tried cobbing into the early  
winter. I am south of Washington, DC. So far I have had no killing  
frost, but it could come any day now. I would like to do a couple  
days more work on my experimental greenhouse, The north and west  
walls are being made from rototiller wood chip cob. Since I am mixing  
with a tiller I could probably continue working till the ground  
freezes, but I know that at some point the daily freezing and thawing  
cycles will prevent my cob from hardening.  I don't know when that  
point is.
	 After the first frost we will probably have a week or two of good  
drying weather before we start getting hard freezes, and even then we  
will not get anything that will freeze deeper than a few inches till  
mid to late December.
	I need to know how far I can push winter cobbing. It would be really  
nice to have a partially useable structure next spring.
