The Asensetek Lighting Passport spectrometer, when combined with the Spectrum Genius Agricultural Lighting APP (SGAL) provides the horticultural industry with a professional tool for assessing, selecting and monitoring growth lamps over time.  More powerfully, integrating this data with plant growth characteristics and analysing over time allows horticulturists to optimise lighting for efficient, healthier plant growth.

  • “Understand” the real needs of plants and produce indoor plants more efficiently
  • Choose the most effective growth lamps
  • Track combined growth and lighting data over time
  • Analyse trends and establish standards for different plant types
  • Optimise time to flower, shoot:root ratio
