algae/mould

Hi all.
Why in my unheated greenhouse has the surface on my seedling compost started to turn a green mouldy/algae green. In time will the seedlings perish because of this.

Many thanks
Andy

Mine do that sometimes, AndyTwin. I think it's algae and occurs when the compost is very damp. I use a fine little plastic 'fork' (or even sometimes a kitchen knife) to break the surface between the seedlings to let the compost breathe and dry. Unless you really leave it to cake the entire surface, I on't think it will harm the seedlings.
