Metal Halide

Metal Halide lamps are good for growing but not so good for flowering.

  • Used to keep plants short
  • lower lumen output than HPS will slow the crop down - good if you are waiting for a flowering crop to finish.
  • Not necessary but can be a tool used for height control and/or speed of vegetaive grow cycle.
  • if unsure please ask. We usually recommend HPS with grow and flower spectrum for entire vegetative and flowering cycles.
