Best seed starting supplies!
These are seriously the best seed starting supplies. The 4-cells are perfectly sized for potting up tomatoes and peppers from the 6-cells. I also start cucurbits directly in the 4-cells, and it works great. These are incredibly sturdy, and so easy to clean and reuse. The hole at the bottom makes transplanting a breeze, with far less stress for me and my baby plants. :)
