I keep it slightly moist, the colony is big enough now for the workers to constantly carry water to the nest. However in the winter when they hibernate i tend to keep it more moist to prevent dehydration etc.
If your y-tong is dark, warm and moist and your tubes are exposed to the light then they should move on their own fairly quick. The key is to make one place nicer than another. That way they will move on their own.



But my colony is kind of small. 


Its so great !! Keep it up
