Seeds need a cool, dry place to retain viability. Choose varieties that will both produce well and sell well in your area. Hybrid seeds are more expensive than open-pollinated varieties. Containers There are a wide variety of containers available for starting seeds for transplants. Most growers start seeds either in flats or in cell packs.
Flats can be of plastic or wooden construction.
The main advantage of using flats is that more plants can fit into the same space if plants are in flats. However, if you start seeds in flats, you will need to transplant to larger cell packs or to individual pots as the seedlings get bigger. Seeding directly into cell packs saves time, because transplanting into a larger container later is not necessary. For tomatoes and peppers, 72-cell packs work well. Other types of containers include clay pots, plastic pots, peat pots, and compressed peat pellets.
