Wet greenhouse

[Gameydave]

Hi I just got another greenhouse off facebook unfortunately it's been soaking wet inside every morning and had ice on glass inside yesterday, does anyone know how I can rectify this please I'm in the uk

Is the greenhouse completely closed--no fan, no ventilation from the roof, no way for air to get in and moisture to escape? If it is totally enclosed, either replace a glass pane with a ventilation pane (looks like a big Venetian blind that you can open and close) or get a fan and leave the door ajar for two or three hours a day with the fan blowing out.
I envy you your greenhouse. I had a small one when we lived in town, but now on the farm the winds would take the poor thing down, so no greenhouse here!

Is there any beading on the glass?
Do you have the glass overlap the correct way?

I live in a very windy area; have you considered full-panel glass & bar capping? I have an 8x12 Elite Belmont.
