Hi Mike and All

Much of the water generated by the metabolism of sugars will be lost as moist air circulates and escapes through the entrance or small spaces around the boxes.  The remarkable warmth generated by the spring brood nest must be a potent factor in the removal of moisture from the hive.

So, although a colony will be generating and releasing prodigious quantities of water, there must surely still be a considerable deficit at this time of year in many hives, as rapid access is required to essentially dehydrated stores.  

It is clear that bees do go out looking for water, and at this time of year it may be a risky activity.  So - what about these absorbent boards?  Do they greatly restrict flights out for water?

all the best

Gavin
