365–400nm UVA and 730nm Far Red Meter, Photon Flux Testing Tool for LED Grow Lights B0CG5LF4L1
Direct Measurement of UVA and Far Red Measure 365–400nm (UVA) and 730nm (Far Red) photon flux directly. Designed for growers who need real data beyond standard PAR readings. UVA is beneficial in moderation, harmful in excess. Benefits: A. Photosynthesis, enhances efficiency. B. Resistance, promotes protective compounds. C. Development: Affects growth and flowering. Drawbacks: A. Cell Damage, harms DNA. B. Water Loss, increases evaporation. C. Growth Inhibition, can hinder growth. 730nm benefits. A. Photosynthesis Promotion, 730nm light can be absorbed by plants, enhancing photosynthesis. B. Growth Regulation: Promotes elongation growth, helping to form stronger stems and leaves. C. Flowering Improvement: Helps regulate flowering time and increase the number of flowers. No Cross-Response from PAR Range Light. Insensitive to blue, green, and 600–700nm wavelengths, so readings focus only on UVA and 730nm without interference. Multi-Point Measurement for Real Coverage Insight. Measure μmol/m²/s at different locations to evaluate how light is actually distributed across your grow area. Because light is never uniform. Simple, Secure Bluetooth Connection. Connect directly to your smartphone via Bluetooth. Works fully offline—no internet required for measurement.
