Could also be temperature and humidity etc.

  Could be but I don't think it was the case. Unless it a very sensitive, there wasn't a lot of difference, it was summer, house was open, low humidity if at all.

    Still, objects in sunlight are significantly hotter than air temperature, and molds have pretty strong requirements for developing, temperature wise.
