BioBizz Bio pH- — Organic Citric Acid pH Regulator
An organic pH Down regulator that keeps acidity/alkalinity levels optimal for nutrient absorption and beneficial microorganism health. Contains citric acid — a powerful natural pH adjuster that actually boosts beneficial bacterial populations rather than harming them (unlike synthetic phosphoric acid pH Down which is broadly antimicrobial). Essential for strict-organic BioBizz growing schedules.
Keeps root-zone pH optimal — proper nutrient absorption range maintained
Compatible with certified-organic growing — doesn't compromise BioBizz organic integrity
Supports microbial life in growing medium — actively helps rather than suppresses microbiome
Reliable pH reduction — does the actual job without compromising biology
Works with any base nutrient — not BioBizz-specific, universal organic pH Down
Who it's not for:
For strict-synthetic hydroponic setups, generic phosphoric acid pH Down (Growth Technology pH Down, PH UP range) is cheaper. UK tap water is typically alkaline — you'll use Bio pH- more often than Bio pH+. Add small amounts at a time, stir, re-test before adding more. Don't over-correct; citric acid pH Down works quickly but can overshoot if poured.
