There are many different size cell trays to choose from. If you want to get started propagating your seedlings you need to figure out which cell tray is best for your needs. We will go over the different options to help you select which is best for you.
32 Cell trays are the largest cell trays that we carry. Each cell is 2" x 2" giving your seedlings plenty of room to grow. Each cell has a removable insert for easy transplantation. They are great for plants that are more prone to transplant shock such as cucumbers, melons, squash and pumpkins. These cell trays will encourage faster growth as there is more access to nutrients and plenty of space.
72 Cell trays are the most popular choice. They are a good balance between space for growing and seedlings per tray. Each cell is 1.5" square and 2.25" deep which makes them a great option for a large variety of plants. These are also a good choice for the vine plants, however you will want to transplant the vine plants earlier than you would with the 32 Cell trays.
128 Cell Trays are a great choice if you have many plants that you wish to grow while they are still small seedlings. Each cell is 1" square and 2.25" deep. You will be able to plant 78% more seedling with 1 tray than the more common 72 Cell.
200 Cell Trays are an excellent tray if you want to be economical about growing Cole Crops and Lettuce. You will be able to grow ~2.8 times as many plants with one tray as you would with a 72 cell tray. Each cell is 0.75" square and 2.25" deep. However you will need to transplant your seedlings at an earlier stage.

We have compiled some of the most common questions to create a "how to guide" for seed starting along with other gardening tips.
At What Stage Do You Transplant Seedlings? Seedlings grown in cell trays need a sufficient root system in place before transplanting outdoors. Waiting until the seedling develops its second true leaf is one way to determine if a seedling is ready or not - but that is not always a hard and fast rule.
