General Hydroponics pH Up - 1 Gal

Raise Low Reservoir pH Gradually - 1 Gal Bottle

Nutrient solutions can drift acidic as plants feed, when source water is poor, or when the growing media is unstable. Left alone, that drift can limit how well plants take up nutrients. General Hydroponics pH Up is a base-type adjuster that raises pH in small, controlled steps, so you correct the reservoir without overshooting.

The 1 Gal size suits a regular indoor grower or a small hydroponic setup that checks and corrects pH often. It also gives hobbyists plenty of supply for several reservoir changes. Larger commercial operations may want to compare it with their total reservoir volume.

Key Features & Benefits

• Raises low pH — corrects a nutrient solution that has turned too acidic.
• Small, incremental dosing — add a little at a time and retest, so you stay in control of the final reading.
• Made for hydroponic reservoirs — fits routine pH management in recirculating and reservoir-fed systems.
• 1 Gal size — a practical quantity for repeated adjustments across vegetative growth and flowering.

Who Should Use General Hydroponics pH Up

Use it if you run a hydroponic system and your pH meter or test kit shows readings below your target range. It suits home gardeners and licensed commercial growers who adjust reservoirs regularly.

Frequently Asked Questions

Q: When do I need pH Up?
A: Use it when a reading shows your nutrient solution is more acidic than your target. Low pH can follow poor-quality source water, unstable media, or fast plant growth that pulls nutrients out quickly.

Q: How much should I add at once?
A: Add a little at a time. Mix, wait, and retest before adding more, because a small amount can shift pH noticeably.

Q: Why does the pH of my reservoir keep changing?
A: Plants absorb nutrients unevenly, and water quality and media type also affect the solution. Regular testing shows when a correction is due.

Q: What does pH measure?
A: pH is a scale of how acidic or basic a solution is. In hydroponics, keeping it in a suitable range helps plants take up nutrients.

Q: Is it a replacement for a pH down product?
A: No. pH Up raises pH only. If your solution reads too high, you need a separate product that lowers it.

Q: How should I handle it safely?
A: Read the label and safety data sheet before use, keep it away from children, and avoid skin and eye contact.
