This article presents a comprehensive guide to selecting grow lights in four steps. First, clarify lighting needs through three self-inquiries: coverage area, plant types, and installation location. Second, estimate grow light performance by calculating PPF (Photosynthetic Photon Flux), assessing size suitability, and identifying essential functions. Third, compare products by checking certifications (e.g., 3C), spectrum compatibility, and PPF parameters. Finally, evaluate prices to choose cost-effective options. The core logic emphasizes aligning choices with specific planting requirements for optimal plant growth. Keywords: grow light selection, PPF/PPFD, spectrum, cost-effectiveness, installation method.
