These 1020 plastic plant trays without holes are designed to meet various growing needs. With dimensions of 10 in. x 20 in. at the bottom and 11.2 in. x 21.6 in. at the top, and a depth of 2.52 in. they fit most standard plant growing trays and shelves, providing enough space to hold nursery pots. Made from high-quality PS material, these heavy-duty trays have a thickness of 1.8mm, making them stronger than ordinary 1020 trays, with excellent resistance to twisting and bending. The bottom features deep concave-convex stripes, which help retain more water for seedling pots to absorb over longer periods, while also enhancing the tray's bearing capacity and preventing bending. Versatile in use, they are ideal for growing microgreens in greenhouses, holding and transporting seedling pots, and accommodating a large amount of soil for starting seeds, transplanting seedlings, and bulk transfers. They can be used outdoors in cold temperatures or on heating mats in high temperatures, offering flexibility for different growing environments.
