I love these green trays but not for starting seedlings. I start in an open tray, normally in a propagator. Then when picking out use these trays.

These are dianthus but I still use this kind of thing for cosmos and everything else to germinate. Apart from sweet peas I put those straight in a small pot each

Some seeds need light to germinate so I’d leave the lid off

Once pinched out and potted on

Leave the lid on until the seedlings start emerge wipe the I side of the lid daily to prevent damping off as soon as they come through remove the lid
