講左d color temperature既理論,肉眼見到既光,不是真實顏色
葉綠素a/b,祇要紅藍光,所以植物燈偏重紅藍,不是全對,其實其他顏色都重要,原文:"3000K/4000K (warm) LED spectrums happen to have an ideal amount of blue light, and a good amount of yellow light for growth power. Even though red and infrared are mostly left out, it’s a decent growth spectrum."
結論係冇乜結論
不過令人懷疑黃光LED好定白光LED好,特別係最後張圖,warm white LED綠光最多,我用緊黃光
