Central Coast Garden pH Up Solution - 1 Gallon - 35% Potassium Hydroxide - Maximum Strength

Central Coast Garden pH Up Solution - Maximum-Strength 35% KOH pH Adjuster for Commercial Reservoirs

Central Coast Garden pH Up Solution is one of the most concentrated pH-raising products available — formulated at 35% potassium hydroxide (KOH) to quickly and efficiently elevate pH levels in nutrient solutions and irrigation water. Designed for commercial reservoirs and large-scale hydroponic operations where standard-concentration adjusters would require impractical volumes to achieve meaningful pH shifts, this 1-gallon format delivers the power and efficiency that high-volume growers demand.

Key Features & Benefits

• Maximum-strength formula — 35% KOH: Among the highest-concentration pH Up solutions on the market — far more potent than standard formulations, requiring far less product per pH point of adjustment.
• Fast pH elevation: Potassium hydroxide raises pH quickly and predictably in nutrient solutions and reservoir water.
• Commercial reservoir optimized: The 1-gallon size and high concentration are purpose-suited to large reservoirs, recirculating systems, and commercial-scale growing operations.
• Prevents nutrient lockout: Maintaining pH within the optimal 5.5-6.5 range ensures all nutrients remain bioavailable — pH drift outside this range causes nutrient lockout and deficiencies that stunt growth and reduce yields.
• Economical cost-per-use: Higher concentration means significantly lower volume per adjustment compared to standard-strength pH Up products.

Who Should Use This

Ideal for commercial greenhouse operators, large-scale hydroponic facilities, and CEA growers managing high-volume nutrient reservoirs where frequent, precise pH corrections are required. The 35% KOH concentration makes this the practical choice when standard-strength products are simply too dilute for efficient use at scale.

Compatibility

Compatible with nutrient solutions and irrigation water in all hydroponic and soilless growing systems. Always add pH adjusters slowly and in small increments, mixing thoroughly before re-testing. Due to the high concentration, a little goes a long way — always use caution when handling KOH solutions and wear appropriate PPE.

Frequently Asked Questions

Why is a 35% KOH concentration beneficial for commercial growers?

Commercial reservoirs hold hundreds to thousands of gallons of nutrient solution. Standard-concentration pH adjusters would require large volumes per adjustment. At 35% KOH, a small amount raises the pH of even very large reservoirs efficiently, reducing product consumption and storage requirements.

What is the ideal pH range for hydroponic nutrient solutions?

The optimal pH range for most hydroponic crops is 5.5-6.5. Maintaining pH within this range ensures all macro and micronutrients remain fully soluble and available for uptake. pH outside this range leads to nutrient lockout and visible deficiency symptoms.

How much should I add per adjustment?

Due to the high concentration, always add this product in very small increments — a few milliliters at a time in large reservoirs. Mix thoroughly and re-test pH before adding more. Overshoot is much harder to correct than undershooting.

Can this be used in all hydroponic growing systems?

Yes — this product is suitable for all hydroponic and soilless growing systems including NFT, DWC, ebb and flow, drip, and recirculating systems. Always dilute appropriately and never add directly to a nutrient concentrate.
