Who This Is For

  • Growers using base nutrients who see slow development because the solution pH dropped below the intake window
  • Operators managing various media like coco or rockwool who need a single reliable solution to stabilize pH levels
  • Users who find themselves over-correcting pH and need a buffered solution for more precise control

What We Found

  • The potassium carbonate base adds helpful buffering that keeps the solution stable longer between adjustments.
  • The liquid formulation mixes much faster than dry adjusters, which prevents hot spots in the reservoir.

What Users Say

  • Growers who switched from generic adjusters say their pH stays stable for days, reducing the time spent monitoring
  • Users who moved to this formula say the added potassium boost eliminated the yellowing they saw in early flowering

General Hydroponics pH Up (Liquid)

Low pH levels lock out essential nutrients and prevent plants from reaching their full potential. General Hydroponics pH Up uses a potassium hydroxide and potassium carbonate base formula to precisely raise nutrient solution pH, ensuring optimal nutrient availability for plants fed with General Hydroponics FloraGro Nutrients or other base formulas across all growing media types—from rockwool and coco to soil and water culture systems.

The General Hydroponics pH Up liquid formulation delivers premium buffering capacity that maintains stable pH levels between additions. This concentrated base solution works quickly when nutrient pH drops too low, bringing it up to the optimal 5.5 to 6.5 range where most plants thrive. The potassium-based formula not only adjusts pH but also contributes beneficial potassium to your nutrient solution, supporting healthy plant development.

Compatible with all nutrient lines and growing systems, this pH adjuster integrates seamlessly into your feeding routine alongside essential supplements like General Hydroponics CALiMAGic Nutrients. Add sparingly to your nutrient solution, test pH levels, and repeat application until you achieve the desired reading—precise control without guesswork.

Features

⚖️
Premium pH Buffering

Maintains stable pH levels longer between adjustments, reducing monitoring frequency and labor.

🌱
Universal Growing Compatibility

Works with hemp, vegetables, herbs, fruits, flowers in all media types and cultivation methods.

Fast-Acting Formula

Quickly raises pH to optimal 5.5-6.5 range for maximum nutrient availability and uptake.

🔬
Precise Dosing Control

Add small amounts at a time for accurate pH adjustment without overshooting target levels.

Industry-Trusted Performance

Widely recognized as a consistent, reliable pH adjuster by commercial and hobbyist growers worldwide.

How to Use

Add General Hydroponics pH Up sparingly to your nutrient solution, a little at a time. Test pH levels after each addition and repeat application until desired pH is achieved. The recommended pH range for most plants is 5.5 to 6.5. The quantity necessary for pH adjustment will vary depending on the strength of the nutrient and the purity of your water. Use General Hydroponics pH Test Indicator for accurate testing of nutrient pH.

This product raises nutrient pH. If your solution levels are too high instead, you should use General Hydroponics Liquid pH Down Nutrients to lower them safely.

Support & Manuals

FAQ

What is the ideal pH range for my nutrient solution?+

The recommended pH for most plants is between 5.5 to 6.5. This range ensures optimal nutrient availability and uptake across different growing media. Use a pH test indicator to monitor your levels and adjust accordingly with General Hydroponics pH Up.

How much pH Up should I add to my reservoir?+

The amount needed varies depending on your nutrient strength and water purity. Always add pH Up sparingly—a little at a time—then test pH levels after each addition. Repeat this process until you reach your desired pH level to avoid overshooting.

Can I use pH Up with any nutrient brand?+

Yes, General Hydroponics pH Up is compatible with all nutrient lines and growing systems. Its potassium-based formula works universally to raise pH in any hydroponic, soil, or soilless growing setup without interfering with other nutrients.

What growing media can I use this pH adjuster with?+

General Hydroponics pH Up works with all growing media including rockwool and coco, and is particularly useful when balancing solutions containing General Hydroponics Armor Si Nutrients. It's designed for versatility across hemp, vegetables, and other high-value crops.

Does pH Up provide any additional nutrients?+

Yes, the potassium hydroxide and potassium carbonate formula contributes beneficial potassium to your nutrient solution. This not only adjusts pH but also supports healthy plant development, particularly during flowering when used with supplements like General Hydroponics Liquid KoolBloom Nutrients.

How does pH Up provide premium buffering?+

The potassium carbonate in the formulation acts as a buffering compound that helps stabilize pH levels after adjustment. This means your nutrient solution maintains the target pH range longer between applications, reducing the frequency of monitoring and adjustment compared to non-buffered alternatives.

What's the difference between liquid and dry pH Up?+

Liquid pH Up works faster and dissolves instantly in nutrient solutions, making it easier to achieve precise pH adjustments. It's ideal for growers who need quick, accurate pH control without the extra mixing step required by dry formulations.

Why does my pH keep dropping after adjustment?+

pH drift is common and can be caused by plant nutrient uptake or water quality issues. While pH Up includes buffering to minimize drift, you should still monitor levels regularly and adjust as needed with pH Up or the high-volume General Hydroponics Pro pH Down Nutrients to maintain the optimal 5.5-6.5 range.
