TotalGrow Light Spectrum

Photonic Distribution Plot for TotalGrow's Broad Grow Spectrum
Summary of the Impacts of Photons of Various Wavelengths/Colors on Plants
TotalGrow’s Solid State Volumetric mixing of light has significant advantages:
  • Provides optimal light in the spectra that plants need most for efficient and healthy growth.
  • Incredible uniformity of light distribution over the plant grow area, eliminating hot and cold spots that inhibit uniform growth.
  • Designed to produce much better plant growth while using less wattage than competitive technologies.
  • Environmentally friendly Solid State Lighting Technology. (No heavy metal vapors, HAZMAT materials or neuro-toxins).
  • Contains no moving parts to eliminate noise vibration and maintenance.

High Pressure Sodium (HPS) Comparison Button Metal Halide Spectrum's Photonic Distribution
  • Metal Halide lamps have output peaks in the blue, green and yellow areas of the PAR spectrum.
  • Contains heavy metal vapors and toxic materials, which commonly include mercury, radioactive krypton-85, thallium, dysprosium, thulium, cesium, cerium or other rare earth elements, lead, and asbestos coatings.
  • Metal Halide lamps can be prone to exploding.
  • “If the arc tube is broken, handling in a well-ventilated area, and local exhaust ventilationor personal protective equipment may be needed” (GE MH MSDS -
  • As MH bulbs reach end-of-life, they can require more electricity to produce less light.
  • Up to 50% of Metal Halide bulbs may burn out before they reach their lifetime hours rating.
  • Long warm-up periods can waste up to 15 minutes of energy consumption per light when first powered.
  • For plants to properly flower and fruit they generally require stimulation by the correct balance of red (620-700nm) and far red (700-750nm) light. This is lacking in metal halides and is difficult or impossible to generate even at high power.
  • BLUE: The blue output has appearance and plant health benefits including stem elongation inhibition and proper pigmentation stimulation.
  • GREEN/YELLOW: Most output is in the yellow-green spectrum, which is the least efficient light region for plant growth. Plants are green because they reflect the most green light rather than absorbing and using it.
  • RED: The minimal output in the highly efficient red spectrum results in inefficient overall growth.
