THROUGH THE Cultivator's LENS Hands-On Evaluation

  • You are upgrading your light coverage because your current 2x2 setup leaves the edges of your 3x3 tent dark.
  • You are switching to a unibody board because moisture and dust in your grow space keep gunking up your open-sink LEDs.
  • You are integrating smart controls because manually adjusting your dimmer every morning is becoming a tedious chore.

  • The aluminum unibody board feels much more solid than the typical cheap boards made from bolted plates.
  • Heat buildup is never an issue because the entire unibody acts as a single large heat sink for the diodes.

  • Users who moved up from the S22 say the extra 110 watts finally gave them the dense canopy they wanted in a 3x3.
  • Buyers operating in humid tents report the sealed board design prevents the corrosion often seen on open LEDs.
