The plants prepared in the pro tray are better than the plants prepared in the field. Disease free and high quality seedlings can be grown in a tray in a protected environment. Apart from this, seed growth and germination in the pro tray is good. At the same time, root development is also great because of adequate space availability. Plants can be shifted from one place to another depending upon the season. Seedlings raised in trays can be transported from one place to another easily.
