Ok, mlld here but I would have your bay tree outside. I think its too warm and humid where it is right now. I would bubble wrap your pot and fleece the top amd, yes, leave it in a sheltered spot outside.
Looks like botrytis to me on your herbaceous plugs. I would spray with fungicide....leaves, stems and soil surface. Ironically,,the wet spray itself creates a damp atmosphere so I suggest you spray early morning to enable leaves to dry quickly. Plants need plenty of air circulation too.
Re echinaceas, they seem susceptible to pathogens during the winter, ironically caused by being too warm at their crowns. At least, that's my experience so I try not to fleece them in the greenhouse. Cool and dry.....dryish. I came to realise this when echinaceas not unduly protected fared better than those fleeced.
