SPAR-1
PAR (Light) SENSOR

The SPAR-1 is a precision light meter that measures Photosynthetically Active Radiation (PAR)—the plant-useable light produced.

Maintain ideal lighting levels for each growth stage, reduce wasted energy, and improve consistency and growth.

Connect the SPAR-1 to a Croptiva controller and select how you want to control your PAR level. Active or Passive.

  • Active Lighting Control (Automated):
    When the SPAR-1 is used, the controller can “actively” automatically adjust your lighting to maintain the exact PAR level you select

  • Passive Monitoring (Manual Control):
    The SPAR-1 can also “passively” continuously measure PAR so you can manually adjust lighting based on real-time PAR light level readings
