Who This Is For

  • You are building a custom feed schedule because your current base nutrients lack the potassium needed for late-stage
  • You are opting for a chloride-free supplement because your root systems are showing signs of salt stress and buildup

What We Found

  • Unlike liquid boosters that are mostly water, this powder stays shelf-stable and potent for years.
  • Mix this in a small jar of warm water first to get it fully dissolved before adding it to your main reservoir.
  • We suggest keeping the bag tightly sealed because this powder is a magnet for moisture in humid grow rooms.

What Users Say

  • Users who moved away from chloride-based salts say they stopped seeing the tip burn that often ruins a late harvest.
  • Operators say they reduced their storage footprint and shipping costs by switching from heavy liquid jugs to powder.
