Product Description

Push your propagation potential to the max with our 512 Cell Matte Black Plastic Seedling Tray, the ideal choice for high-density seed starting in a compact, professional format. Designed to fit all standard 1020 trays, this ultra-efficient tray features 512 individual plug cells, each optimized for rapid germination and tight-space growing. Crafted from 1.0mm thick plastic, this tray delivers excellent durability while maintaining flexibility for repeated use. The matte black finish adds a modern touch while reducing glare under grow lights. Each of the 512 cells is carefully molded to create an individual microenvironment for your seeds. The plug tray design encourages uniform root development by separating seedlings and preventing entanglement, which makes transplanting cleaner and faster. Ideal for microgreens, herbs, onions, and other short-cycle crops, this tray is perfect for growers looking to increase their output without expanding their footprint. Why use a 512-cell tray? It’s designed for maximum efficiency, allowing you to start hundreds of seeds in a single tray. The compact cell size is ideal for crops that germinate and transplant quickly, or for growing delicate crops like lettuce and basil that don’t need deep root systems at the seedling stage. Matte black trays also help maintain stable soil temperatures and improve light absorption—important factors when growing under artificial lights or in temperature-variable environments. Each cell includes a precisely engineered drainage hole to prevent root rot and promote airflow, helping to develop healthy, fibrous roots. Produced by a top-tier Korean manufacturer, this tray is built to meet the quality standards of commercial growers while remaining accessible for home gardeners. Lightweight, stackable, reusable, and easy to clean, it’s the smart choice for anyone looking to grow more in less space—without sacrificing plant health
