Home gardening: an ideal starting point for vegetables (tomatoes, peppers, cucumbers), herbs (basil, mint), and flowers (petunias, marigolds). Professional seedling cultivation: Small nurseries and farms efficiently cultivate neat and robust seedlings, reducing seedling cultivation costs. Fun education: excellent teaching tools for parent-child activities, school nature class practice, and observing the budding of life FAQ Q: What is the size of a single tray? What is the size after combination? A: A single tray is unfolded by approximately 4.8 cm * 4.8 cm , and only requires a small space when folded. After combining 4, it is approximately 48 cm * 25 cm , perfectly matching the matching base. Q: Is PET material safe? Is it suitable for growing vegetables? A: Absolutely safe! We use food grade PET plastic, which is non-toxic, odorless, and meets environmental standards. It is a safe choice for cultivating edible crops such as vegetables and herbs. Q: How does the acupoint support weight? Will it deform when filled with wet soil? A: The design is sturdy, and the PET material has good toughness. It can be stably supported after conventional seedling filling and watering, and is not easily deformed or broken. Q: Do I have to use it with a base and lid? A: The tray can be used alone, but it is highly recommended to pair it with a base and a high lid. The bottom tray is leak proof and water storage, while the high cover provides moisture retention, insulation, and insect prevention. It can significantly improve seed germination rate and seedling growth quality, and is a key guarantee for successful seedling cultivation. Q: Do I need to purchase additional bottom support and high cover? A: Yes, the black rectangular base and white high cover are specialized components that need to be purchased separately. They perfectly match the size of the plug, together forming an efficient seedling system.
