Precise pH down that stays put

Terra Aquatica pH Down gives you fast, precise pH control for hydroponic and soil systems, lowering acidity without upsetting the nitrogen and potassium balance of your feed. Its organically buffered formula holds pH steady for days, even during rapid plant growth, so your nutrients stay fully available.

A little goes a long way, and it doubles as a mild line cleaner to keep your system running smoothly. It is stocked locally in Windhoek, Namibia for fast delivery. Pair it with Terra Aquatica pH Up for complete pH management.

Key Features

  • Fast, Precise Control: Adjusts pH in hydroponic and soil systems without upsetting N/K ratios.
  • Organically Buffered: Stabilises pH for days, even with rapid plant growth.
  • Calcium-Taming Blend: Manages hard-water issues to keep nutrients fully available.
  • Dual Action: Adjusts pH while feeding plants with balanced phosphates and nitrates for vigorous roots, foliage and flowering.
  • System Care: Works as a mild line cleaner, and a low-dose foliar spray helps remove pesticide residues.
  • Optimal Range Support: Designed to maintain nutrient solutions at pH 5.5–6.2 for maximum uptake.
Specifications
