General Hydroponics pH Down - 8 fl oz

Lower Solution pH in Small, Controlled Steps - 8 fl oz Bottle

Even a strong nutrient recipe can underperform when solution pH drifts out of range. General Hydroponics pH Down is a pH-adjusting liquid that lowers the pH of nutrient solution so nutrients stay more available to plants. You add it a little at a time, stir, and test until you reach your target.

The 8 fl oz bottle suits home gardeners, first-time hydroponic growers, and small indoor setups that need a reliable pH adjuster without a large container to store. Commercial growers can use it for trials or for spot adjustments.

Key Features & Benefits

• Liquid pH adjuster — mixes into nutrient solution and lowers pH.
• Phosphoric acid formulation — the manufacturer describes it as food-grade phosphoric acid.
• Gradual dosing — small additions let you approach the target pH without overshooting.
• Designed for hydroponic and liquid-feed programs — fits recirculating systems and reservoir feeding.
• Single 8 fl oz bottle — a compact size that is easy to store.

Who Should Use General Hydroponics pH Down

Frequently Asked Questions

Q: When do I add pH Down?
A: Mix your nutrients into fresh water first, then add pH Down. Adding it after the nutrients gives you an accurate reading of the finished solution.

Q: How much should I add at once?
A: Add a little at a time. Stir, test the solution, and repeat until you reach the target pH.

Q: Why does pH matter if my nutrient recipe is strong?
A: When pH is out of range, plants take up nutrients less effectively. Adjusting pH helps keep the nutrients you supply available.

Q: What does pH Down do in a nutrient solution?
A: It is an acidic liquid that lowers the pH of the solution. pH is the measure of how acidic or alkaline the water is.

Q: Is it safe to handle?
A: It is a corrosive product that can cause severe skin burns and eye damage. Wear gloves and eye protection, and read the safety data sheet before use.

Q: Can I use it in a liquid-feed program that is not hydroponic?
A: The manufacturer designs it for hydroponic and liquid-feed programs. Test the solution after each addition either way.
