Grow light Meter

A quality grow light meter is an essential tool in determining if your crop is receiving the appropriate light and environmental conditions for healthy growth.


Quantam PAR Grow Light Meter LGBQM2

  • Measures PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from the 400 to 700 nm
  • Fully portable handheld grow light meter
  • Measures up to 10,000 units of micromole per meter squared per second (umol/m2/s) which is also called Photosynthetic Photon Flux Density (PPFD)
  • Tethers to computers via USB cable for easy data logging
  • Proprietary Quantum Sensor
  • Ultra-low power consumption with built-in low battery indicator
  • Proprietary data logging software
  • Response curve is almost constant (versus Gaussian for digital meters) which yields a much higher accuracy independent of wavelength being measured- great for measuring LED light correctly

LGBQM2PHOTOBIO Advanced Quantum PAR Meter0.8 lbs.The Advanced Quantum PAR Meter provides accurate and cost-effective measurement for all light sources used to grow plants.  The PHOTOBIO by Phantom Quantum PAR meter is designed to measure PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from 400 to 700nm. There is a proportional relationship between the number of photons absorbed in 400 to 700nm band and the rate of photosynthesis in plants, which is important for horticultural studies and monitoring plant physiology.
HGIOHTActive Air Indoor-Outdoor Thermometer w/Hygrometer0.3 lbs.Active Air’s indoor-outdoor thermometer gives you more. Made of sturdy materials to stand up to the climate of your indoor grow room, this essential tool features a large display to read the current temperature and humidity levels. A remote probe allows you to sample two temperatures at once. Record the high and low points for both temperature and humidity.
