I bought a strange named brand dehumidifier from the good guys for $239. probably not the cheapest available but it was in stock and had a external drain connection. bought some 10mm clear tubing and connected it up and then shoved it out the base of the observatory. its been on for about an hour and already the water is flowing. LOL to offset this i then turned around and spent a small fortune(60 dollars) on 4 par30 LED lights for the outside lights on the house. instead of burning the 4 x 150watt its not 4x 7 watts. hears hoping the offset somehow works
i did look at the delongie one but it didnt have the external drain option
