OK, so I went out today and bought a mini dehumidifier to try and sort this problem out. As I arrived back home I realised we had a power cut going on

!! 5.5 hour without electricity and my girls had only had 5 hours of light before the entire community went dark. Needless to say, the temperature began to drop quickly and I ended up covering them in black bin liners and bringing them into the house where we have a log fire and hiding them behind the couch for fear of them seeing any light even from the fire! What a f**&$g day!! Anyway, once the electricity finally got its head together and we had light, I put em back in their box outside in the boiler house with this new dehumidifier and 3.5 hours later - its doing very little!!! The RH is down to 65 but thats about it! This SO must have happened to someone else - help me please, what did you do to cure it?????????????? Stoned and pissed off - UK!!
