I have a quick question about seeds germinating in a propagator. About half of them have germinated so do I remove them from the propagator or do I leave them in a while longer?

 They are lobelia seeds and I am worried about damping off.

I would take them out as the other half are probably about to pop up anyway.

Keep them some where out of full sun but warm and bright -- they should be fine

Damping off is more likely due to over watering.

Damping off is more likely due to over watering.

Or being in a propagator which still has the lid on (admittedly we don't know if this is the case here.)
