Hi there again. I have been watching my peppers grow and now most are 2 1/2-3" tall, with a couple a bit taller. They are in seed starting trays similar to those of the 72 tray starter kits, approximately 1 1/2" square. The reason I am asking is that the peppers seem to be slowing down in growth. They have been in these homes for approximately 2 months, give a week or so. So I am wondering if it is time to pot up into new larger homes comprised of cups? If so, would they continue their growth? They are healthy and all, but I was just thinking they need to be moved. Thank you for any help in advance.
