How to Dry Pressed Plants?

Forgot to point out that it must be one of the small (ca. 1 ft. cube) 
ELECTRIC jobs.  You want it to stay well away from the presses (6" min) and 
you would never want to use gas or propane, etc.  Also a good idea to sweep 
out plant crumbs on a regular basis.

MDR in College Station Texas, where it is so wet right now
that if you put plants in a press and didn't dry them on purpose, they would 
never dry, and might just keep growing. (Ever see a cactus do that?)

>>We have an ancient herbarium drying cabinet from Lane Science Equipment

>>(past?) the end of its useful life.  A replacement that appears to be
>>identical would cost about $1,600.  We run two courses that require

>>in use roughly one semester out of two, however when it is in use it is
>>usually nearly full.
