Cannabis plants need light to convert carbon dioxide into glucose which is required for growth and development. The plant relies on the sun for light when grown outside. When growing inside,  plants need specific lamps and a light cycle  to stimulate the plant’s growth.

Not all lights are suitable for growing due to light spectrum or intensity.

  • Lamps that are not suitable for growing are: light bulbs, energy saving lamps, halogen lamps, mercury vapor lamps, low-pressure sodium lamps
  • Lamps that are suitable for growing are: fluorescent lighting, HPS lights, HPI lights, LED lights
