some people have been using a Dispensing Needle 14G x 10" https://www.amazon.com/gp/product/B075H5HQ94/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 to add water through the vent.. can get through the bottom mesh... works good for meGood to know. I have some terry cloth bar towels I can use. I may just buy some aquarium tubing and feed it into the water tray and put it through the turning-cord slot since that gets turned off and I can use a syringe to add water without opening it up.
