A good plug tray is usually in black with rectangular or trapezoidal openings. These features prevent the roots from direct sun exposure and potential root circling around the container. Different corp seeding breeding usually require different volume of soil and nutrient, which often result in different hole number on the plug tray. For examples, eggplant is better fitted in the class of 72 hole plate, melons is 50 aperture plate, and pepper is 105 aperture plate etc.
