I hope this is not too dumb a question, But when starting seeds and your using the small pots, do you have to cover those with the plastic on top if they are in a green house?
I also have the the black trays that but not the clear covers and cannot locate any locally so I ordered some online, but can you also use those with no cover if you keep them in a green house or does everything need to be covered with some sort of plastic in the beginning?
Thanks for any advice
