Bodhrans who live in hot dry places need special help to stay alive. If you have a goatskin head on your drum, and live in an area where the weather is very dry or hotter than 75 degrees for long periods, you will notice that the drum head becomes very tight. Drums have been known to split in extreme conditions. To prevent this, you can store your drum in a case with a humidifer or if you have no case, storing your drum in a closet or other small area with an even temperature. In really dry areas, you can put the drum in a plastic bag with a damp rag. Punch a few small holes in the bag to prevent mildew and store in the closet. When you travel cross country through different weather zones, you should provide a case or bag and try to keep the drum at a constant temperature. Wrap it in a thick blanket and set it under pillows. Never leave your drum in the back window of a car or in the trunk.https://finalscope.com/what-is-pva-glue/
