Emerald Harvest pH Up, 1 qt, case of 12

Raise Your pH with Emerald Harvest pH Up

Emerald Harvest pH Up is an alkaline buffer designed to raise the pH of hydroponic nutrient solutions that have dropped below the optimal 5.5–6.5 range. Low pH limits the availability of key nutrients including calcium, magnesium, and phosphorus, leading to visible deficiency symptoms over time. pH Up corrects acidic conditions reliably without causing abrupt spikes.

Formulated as a weak base, pH Up provides controlled pH adjustment that is easy to manage in any hydroponic or substrate-based system. By maintaining the proper pH window, it ensures that the nutrients already present in your solution remain accessible to plant roots, supporting consistent and healthy development across the grow cycle.

Key Features & Benefits

• Raises Low pH Precisely — Brings acidic nutrient solutions into the 5.5–6.5 target range, where nutrient availability is maximized.
• Weak Base Formulation — Acts as a controlled alkaline buffer, allowing gradual pH correction without overcorrection or instability.
• Restores Nutrient Availability — Low pH locks out calcium, magnesium, and phosphorus; pH Up corrects conditions to make these nutrients accessible again.
• Supports Beneficial Bacteria — Maintains pH stability that promotes thriving populations of beneficial microorganisms in the root zone.
• Compatible with All Growing Media — Works in hydroponic systems, coco coir, soil, and other substrate types.
• Clean Straightforward Formula — Focused on effective pH adjustment without unnecessary additives.
• Pairs with pH Down — Part of the Emerald Harvest pH management duo for complete two-way pH control.

Who Should Use This Product?

Emerald Harvest pH Up is well suited for growers using naturally acidic water sources or highly buffered nutrient mixes that tend to pull pH downward. Coco coir growers and hydroponic operators who experience chronic low pH will find pH Up a reliable corrective tool in their maintenance workflow.

How to Use pH Up

Add pH Up to your nutrient solution in small, measured increments and test pH after each addition. Always prepare your full nutrient solution before adjusting pH, and add pH adjusters to the solution rather than to concentrated nutrient stock. Monitor your reservoir at least once per day during active growth phases to detect and correct pH drift promptly.

Frequently Asked Questions

What is the target pH range for hydroponics?

Most crops thrive at pH 5.5–6.5 in hydroponic systems, with 5.8–6.2 commonly recommended for the broadest nutrient availability.

How much pH Up should I add?

Add a small amount at a time — a few milliliters per gallon is a reasonable starting point — then test and repeat until you reach the target pH.

Can I mix pH Up with nutrients directly?

No. Prepare your full nutrient solution first, then adjust pH. Never mix pH adjusters with concentrated nutrients directly.

Why does my pH keep dropping?

pH drift downward can be caused by plant root activity, organic decomposition, or CO2 uptake. Regular monitoring and adjustment keep the system on track.

Is pH Up safe for all hydroponic systems?

Yes, pH Up is suitable for use across recirculating and drain-to-waste hydroponic systems as well as coco and other substrate media.
