The size of the standard seedling tray is 54cm × 28cm. Due to the different hole diameters, the number of holes ranges from 18 to 800. For cultivating medium and small seedlings, plug trays with 72--288 holes are suitable.
The hole shapes of seedling plug trays are mainly square and round. Square holes generally contain about 30% more substrate than round holes. The water distribution is also more uniform, and the seedling root system is more fully developed.
The color of the seedling tray will affect the temperature of the plant roots. White polystyrene foam disks are highly reflective and are often used for early seedling raising in summer and autumn to reflect light and reduce heat accumulation at the roots of seedlings. In winter and spring, choose black seedling trays because they have good light absorption and are beneficial to the greening of the seedling roots.
Advantages of using plug seedlings:
(1) Save seed usage and reduce production.
(2) Seedlings emerge neatly and maintain consistent growth of plant seedlings.
(3) It can be used with various manual and automatic seeders to facilitate centralized management and improve work efficiency.
(4) The root system will not be damaged during transplanting, and the seedlings will grow quickly and survive.

This seedling plug tray is made of PS (polystyrene) material, which is environmentally friendly, has good toughness, and has good air permeability. It is added with anti-aging agents to greatly extend its service life. Currently, some products on the market are made of PVC (polyvinyl chloride), which has properties: hard, brittle, easy to crack, and relatively unstable chemical properties.
The medium capacity of this plug tray is large, which increases the growth space of the root system and is conducive to the growth of crop seedlings. The product can be used repeatedly for more than a dozen times, saving users money.
Made of PS material, there are no defects or holes, and it is not easily deformed under high temperatures. There are holes at the bottom to prevent the roots from rotting and dying due to excess water. There is a water diversion channel on the inner wall to allow water to reach the bottom better. The four corners are circular, which is convenient for lifting seedlings without damaging the roots. It is widely suitable for substrate seedlings of vegetables, flowers, forest trees and other plants.
