describe: LED plant lamp cup 48 beads 60 beads 80 beads nursery supplement light plant growth lamp cup Project: Plant Growth Light Number of LEDs: 48/80 Base type: E27/E14/B22/GU10/MR16 The effect of spectral range on plant physiology: 1. 280nm 315nm has little effect on morphology and physiological processes. 2. 315nm～420nm chlorophyll absorbs less, which affects the photoperiod effect and prevents strain elongation. 3. 420nm～500nm (blue) has the largest absorption ratio of chlorophyll and carotenoids, and has impact on photosynthesis. 4. 500nm～620nm do not absorb much. 5. 620nm～750nm (red) chlorophyll absorbs "high", which has an important influence on photosynthesis and photoperiod effect. 6. Absorb at 750nm～1000nm, stimulate elongation, affect flowering and seed germination. 7. 1000nm is converted to calories. feature: A full spectrum that is essential and vital for plant growth and flowering (from seeding to harvesting). Plants like the appearance of 525nm Green. If the plant has a sufficiently green appearance, it is healthier. 450nm blue and 630nm red are accelerating leaf growth. 660nm red is to promote flowering. 7000k White will be replaced by HPS, HID, MH. Very suitable for small planting boxes, planting tents, DIY hydroponics, bonsai, gardens, etc. Comfortable, user-friendly and high-performance. notes 1.
