I was not surprised at the Salak Tinggi a big pail of water can dry up within less than 10 minutes.
You know why?
This BH or an abandoned shop lot was let to rot for almost 20 years and with the hot surrounding the whole hole was dried up.
The water that was used during it cement mixing was no longer in the walls or the floors.
They were all zapped out and now let very dry.
So what should you do to wet them?
The best is to wet the floor for the next couple of days with water and at the same time install a humidifier actuated using an auto sensor.
What I did was to set the humidity auto sensor to about 70% RH for a couple of hours and I wet the floor every 30 minutes or so.
The humidifier will automatically run once the humidity drops to 67%RH and once it reaches 73%RH it will stop to operate.
After wetting the floor for a number of hours you can push the humidity setting up to sat 75%RH.
You continue pouring those water on the floor and perhaps on the walls too.
Once the humidity reading stays above 72%RH you might want to push the setting to perhap 80%RH.
You continue doing this until you can get a constant reading of 85%RH (-3 and +3).
Once you have your nesting room humidity stabilized at 85%RH your BH is now within the proper range for those birds to like.
Remember the recommended humidity range is 85%RH-95%RH.
The humidity range will help those birds during their nest building and eggs incubation.
Also remember that if your BH is too dry (below 70%RH) you will experience a kind of empty BH sydrome.
However if your BH is too wet (100%RH and above) you might face the danger of fungus growing on your nesting planks.
Use your knowledge to optimize your BH environment.
