General Hydroponics® pH Up Liquid - 1 Gallon - Potassium Hydroxide & Carbonate Base

General Hydroponics® pH Up Liquid - Reliable pH Adjustment for Hydroponic Nutrient Solutions

General Hydroponics® pH Up Liquid is a trusted, widely used pH adjustment solution formulated to accurately raise the pH of hydroponic nutrient solutions and irrigation water. Formulated using potassium hydroxide and potassium carbonate, this base solution delivers consistent, predictable pH adjustment — a foundational tool for maintaining the 5.5-6.5 pH range that keeps nutrients fully available to plants. Available in a 1 Gallon size to match your operation's volume requirements.

Key Features & Benefits

• Dual-base formula: Formulated with potassium hydroxide and potassium carbonate for reliable, effective pH elevation in nutrient solutions and water.
• Predictable, consistent results: A widely recognized and trusted product line among hydroponic growers for consistent, reliable pH adjustment performance.
• Easy dosing: Add a small amount at a time when your nutrient pH is too low, mix thoroughly, and re-test — adjust further as needed until reaching your target range.
• Prevents nutrient lockout: Keeping pH within 5.5-6.5 ensures all macro and micronutrients remain soluble and bioavailable — pH drift causes lockout and visible deficiency symptoms.
• 1 Gallon format: Available in 1 Gallon to suit commercial and high-volume growing operations.

Who Should Use This

Suitable for hydroponic growers of all experience levels — from hobby cultivators managing small systems to commercial facilities maintaining large nutrient reservoirs. Use alongside GH pH Down Liquid and the GH pH Test Indicator for complete pH management.

Frequently Asked Questions

What is the active ingredient in GH pH Up Liquid?

GH pH Up Liquid is formulated using potassium hydroxide and potassium carbonate.

How much should I add per adjustment?

Add small increments — typically 1 mL per gallon as a starting point — mix thoroughly, and re-test before adding more. The exact amount needed depends on your source water's buffering capacity and starting pH.

What is the target pH range for hydroponic systems?

Most hydroponic crops perform best with nutrient solution pH maintained between 5.5 and 6.5. This range keeps all essential nutrients soluble and available for plant uptake.

Can I use GH pH Up Liquid with other nutrient brands?

Yes — GH pH Up Liquid is compatible with any hydroponic nutrient program and all soilless growing system types.
