Seedlings and Growing On
These are my sweet pea seedlings I planted in early January and they have been in my unheated greenhouse in a polystyrene box with a clear polycarbonate lid and heavy flower pot on top to prevent mice eating them. How do I get ventilation in without letting mice anywhere near them. Or I could bring them indoors but I’m worried they will grow on too quickly. I’ve never grown sweet peas this early and am determined to get good ones this year!
