Complete Growing Kit: Our seed germination kit includes four different-sized germination trays, a germination cover, a germination base, and a light protection cover. The transparent design of the seed germination tray allows you to easily observe the germination status of the seeds and also provides a suitable environment for them to grow quickly. Designed for Improved Sowing Efficiency: The seed germination tray combines a corrugated design and drainage holes to quickly and easily meet the optimal seed growing conditions needed for the planting process. Its wavy construction minimizes seed runoff in the tray during sowing. Excess water is moved and concentrated in the drainage holes and the bottom tray to improve sowing efficiency. Space-Saving and Easy to Store: This seed germination kit has a vertical stand function, allowing it to be positioned upright up to 4, 5, or 6 inches. It can be inverted when not in use to save storage space and facilitate organization. High-Quality, Residue-Free Material: Our seed germination trays are made of residue-free PP material, ensuring no harmful substances are left behind during the sowing process. This maintains good moisture properties and provides a better environment for rapid seed germination. Easy to Operate and Quick to Harvest: Soak the seeds in water during the growing process. Simply rinse the seeds and place them in the germination tray, pour water over the cover, and water them layer by layer, ensuring each layer is evenly coated. It takes about 5 days to harvest delicious bean sprouts. Most importantly, even beginners can get started easily and conveniently. Material: Plastic. Color: Green.
