THROUGH THE Cultivator's LENS Hands-On Evaluation

  • You are upgrading to a 400W board because your current light lacks the intensity to reach your lower canopy layers.
  • You are moving to a unibody light because your last fixture failed after moisture got into the diode housing.
  • You are switching to a UIS system because managing separate timers for every light is a massive labour drain.

  • The aluminum unibody feels much more solid than modular boards and actually stays cool during long summer runs.
  • We noticed the diode spacing on the S44 eliminates the hot spots usually found in the centre of 400W boards.

  • Users who switched to the S44 report that the moisture-resistant seal stopped the diode flickering they had before.
  • Growers using the Smart Controller say they stopped worrying about manual dimming once they set their light recipes.
