The transparent or colorful shell design is a highlight of the transparent (colored) seedling tray. This design is not only beautiful, but also can provide a suitable growth environment for plants according to different light requirements. For example, the white transparent (colored) seedling tray can reflect light in summer and autumn, reducing heat accumulation in the roots of seedlings; while the black transparent (colored) seedling tray has good light absorption in winter and spring, which is conducive to the development of seedling roots.
The hole design of transparent (colored) seedling tray is diverse, usually square and round. Square holes generally contain about 30% more substrate than round holes, and the water distribution is more even, so the root system of seedlings develops more fully. The size and number of holes can also be adjusted according to the plant species and growth stage.
The bottom drainage holes are a key part of the transparent (colored) seedling tray design. These holes can ensure that excess water is discharged in time to prevent root rot. At the same time, they also help the soil to breathe and provide sufficient oxygen for the roots of plants.
In order to facilitate handling and stacking, transparent (colored) seedling trays are usually designed with lightweight and durable materials, such as polystyrene foam, polystyrene, etc. These materials not only reduce the burden on users, but also increase the service life of transparent (colored) seedling trays.
Some high-end transparent (colored) seedling trays are also equipped with intelligent designs, such as automatic irrigation systems. This system can accurately irrigate according to the needs of plants, improve water resource utilization, and reduce human intervention.
The size of transparent (colored) seedling trays is also carefully designed to accommodate the right amount of soil and plants. The size of the standard hole tray is 540mm×280mm, and the number of holes is between 18 and 800. The appropriate specifications can be selected according to actual needs.
In addition, transparent (colored) seedling trays also focus on humanized design, such as setting handles or edges that are easy to grasp, so that users can carry and move them conveniently. These design details improve the practicality and convenience of transparent (colored) seedling trays.
