Canopy Management Protocol

  • Plant Introduction: To prevent light shock or bleaching, the fixture's dimming function should be heavily utilized whenever fresh plants or clones are initially introduced under the light.
  • Height Customization: While the standard baseline hanging height is 16 inches, growers should dynamically adjust this distance upward or downward depending on specific plant health metrics and acclimatization during the introduction period.
Grower's Note: The inclusion of both a 15-foot 240V primary cord and a 120V adapter means you can seamlessly transition this fixture from standard residential utility walls to commercial-scale multi-phase power grids without purchasing extra hardware.
