Hello,

I have realised this green covering on top of most seed trays and pots inside the unheated greenhouse. Is it moss ? Will it affect the plants ? Do I need to get rid of it and how ?

Thanks

it could be algae which means the compost could be too wet.  Algae won't affect germination, but the sodden conditions will.

Oh right ok thanks.So its just keep dry ? And it won't affect already germinated plants ?

It's possible that the damping off fungus has already hatched so best to do some preventative spraying with a damp off solution or cool chamomile tea. Spray, don't soak the surfaces, and scrape away all green stuff off seed trays as well.

Thanks Trill,

I think its algae from googling it on images. If I remember I will try and post a pic of the sweet pea pots which have had it worse.
