CULT: question - hot bed?


Anybody have experience with heating a hotbed with fermenting manure?  I
would like to know how long it will stay above freezing once it finishes
heating up and starts to cool.

Fermenting manure and alfalfa pellets in the 45 gallon tub have reached
90oF this AM, keeping an 8 inch pot of potting soil sitting on top at
nearly 50o with outside air temperatures down to 12oF.

Whole thing is covered with an arched frame of woven wire fencing,
covered with two layers of lightweight Reemay type fabric, anchored with
boards.  Tub is insulated with hay bales tied tightly around the tub.
