pH Up and Down
PREMIUM PH ALKALIZER / ACIDIFIER | KEEP IT IN THE SWEET SPOT
pH Up and pH Down are buffers — a weak base and a weak acid — that correct pH imbalances in a hydroponic nutrient solution. Every essential nutrient has its own pH window for absorption; stray outside 5.8–6.3 for too long and elements like iron or manganese lock out.
Why use it
- Avoid nutrient deficiencies by keeping pH stable
- Keep every essential element available at the root
- Protect your crop — imbalanced pH can damage or kill plants
Good to know
- Emerald Harvest base nutrients and supplements are already pH buffered — running the full line usually needs little adjustment
- The sweet spot for hydroponic gardens is pH 5.8–6.3
- Never mix pH Up with pH Down
Shelf life: 3 years or more stored under normal conditions.
Handle with care: pH Up contains potassium hydroxide; pH Down contains phosphoric acid. Both can burn skin and eyes. Keep out of reach of children, wear protective gloves and eye protection, and use only in a well-ventilated area. Full safety information is on the product label and the linked SDS.
