I have discovered that in a small container (I used 21 
gallon clear plastic restaurant bins for propagating and as 
a seedling "house") even with very high humidity, the 
plants (and the sphagnum moss that they were planted in) 
suffered severe dessication when I had a couple computer 
muffin fans providing lots of circulation. Even with a 
layer of water covering the whole bottom of the bin (the 
seedlings were held above the water by a plastic grid). 

The only answer that I could come up with was very frequent 
watering and not depending on the very high humidity to 
keep the plants moist. I was not using a fogger, and if I 
had, it would run frequently on a timer to counteract the 
wind-caused dessication.

I guess that in addition to wind-chill factor there is also 
wind-dry factor <g>.
