Id put them outside. The greenhouse s likely the cause of the mould. If you don't throw open the doors to the greenhouse wide each day and have an airflow through there there going to be susceptible to mould. Obviously if you have tender plants in there to much cold airflow can damage them.
Stick them outside if there all ready hardened off the air flow outside should stem the mould. If you can stand them on some shingle in their pots to aid drainage even better.

I'd say they've been too cossetted and it's too humid and damp for them. Do you have the greenhouse ventilated? If not, that's probably part of the problem too. It's always a mistake, even in winter, to keep a greenhouse closed all the time - even up here. If you think they're too crowded, pot them on.
Have you a photo?

I think they're fine. Most primulas look pretty rough at this time of year I'd just get them acclimatised a bit, and get them outside. Just err on the cautious side for a few days, especially if more snow/ice is forecast. The wet and windy stuff is fine for them. Keep them somewhere reasonably sheltered from slugs if you can. Up on a table - that kind of thing will do.

The middle one is producing new foliage -or it looks like it in the photo. If they're rotting, they're too wet/damp, and the airflow just hasn't been good enough. You can then get botrytis etc. I don't really water anything in the growhouse over winter [I don't have a full sized greenhouse] There's enough moisture here in the air to keep small plants hydrated, and because mine is now sited on a raised border, it's slightly moister inside than before when it was on the gravelled area. Even though this winter has been the driest I can ever remember in the west, enough rain/moisture gets in through gaps etc, and when temps are low, plants just don't dry out, especially small ones. I just check them now and again. The top is opened every day, regardless of weather, even if it's just a tiny amount. It would only be different if I was growing half hardy things in it, but then again - they wouldn't survive without heat, so they wouldn't be out there anyway.
