Vinotemp question

[markem]

[you had to know that this thread was coming]

Now that it is cooler here in Oregon, I don't keep my vinos plugged in. I have 1lb of 65% beads at the bottom of each vino and 1/2 lb of 65% beads about 3/4 the way to the top. I have Oust fans in each that are set on their backs to draw air up from the lower and push it to the higher areas.

My guage tells me that it is 65% near the top, but 71% at the bottom. This seems like way too small an area to have that big of a swing.

The drain is plugged in each.

Any ideas? No water or other condensate in the vinos outside of the beads. The beads are about 70% white and 30% clear.
