It not only has good thermal insulation function, but also has good reflectivity. Hard plastic seedling plug trays are generally available in black, gray and white. Most growers choose to use black trays, especially for winter and spring production. Black trays have good light absorption, and the conversion of light energy into heat energy is more beneficial to the development of seedling roots. Vegetable seedlings and flower seedlings with a long seedling period, such as begonias, usually use seedling plug trays with larger holes, such as 128 and 200 seedling plug trays; poppies, delphiniums, lisianthus, etc. have deeper root systems. , it is better to choose seedling plug trays with deeper holes.
