I don't have any of this type, which I believe is an intergeneric in the Oncidium family. Generally, if it is potted in bark, allow the bark to almost dry before watering again. If the pseudobulb starts to shrivel, increase watering a bit. That said, too little water is easier to fix that too much water. They tend to rot. In NH, it will need to be inside this time of year as they do not do well with low temperatures (low 50s are about as low as I would go). I hope that helps.
