Emerald Harvest pH Up | 32oz

Liquid pH Raiser for Balanced Nutrient Solutions, 32oz

A reservoir or feed batch that drifts below its target pH window locks certain nutrients out of reach even though they're still fully dissolved in the water, so a grower can be feeding on schedule and still see deficiency symptoms show up. Emerald Harvest pH Up is a concentrated liquid additive built to nudge that solution back upward in controlled increments until it settles inside the range a given medium calls for.

The 32oz bottle is sized for growers testing Emerald Harvest's line for the first time or maintaining a single small reservoir, where a full gallon of adjuster would otherwise sit unused for months.

Key Features & Benefits

• Raises solution pH in small steps — moves a batch upward gradually so growers can retest and stop right at the target reading instead of overshooting.
• Concentrated liquid formula — a small dose relative to reservoir or tank volume means one bottle covers many feeding cycles.
• Works across growing media — the same correction applies whether the water is headed into a hydroponic reservoir, a coco coir feed, or a soil watering can.
• Part of a compact additive lineup — pairs with Emerald Harvest's pH Down, Cal-Mag, and Sturdy Stalk additives for full nutrient-solution management.

Who Should Use Emerald Harvest pH Up

This fits growers who test solution pH before every feeding and need a dependable way to bring it up when it drifts low, which shows up often with soft or reverse-osmosis source water or with acidic base nutrient concentrates. It works the same way whether the grower runs a hydroponic reservoir, a coco program, or soil containers.

About Emerald Harvest

Emerald Harvest formulates its nutrient and additive line in Santa Rosa, California, keeping the catalog intentionally short: a few base nutrients, a handful of supplements, and water-chemistry additives such as pH Up and pH Down, sold to commercial growers, independent cultivators, and retail accounts.

Frequently Asked Questions

Why does nutrient solution pH need correcting in the first place?

Nutrient solubility and root uptake both depend on pH staying inside a fairly narrow window, and once a batch drifts outside it, certain elements become harder for roots to absorb even though they're still present in solution. Growers test and adjust pH before every reservoir change or watering so the nutrients they're already paying for stay available to the plant.

How much pH Up should I add to a batch of nutrient solution?

Add it in small increments, mix thoroughly, and retest with a calibrated meter or drop kit before adding more, since the dose needed depends on starting water alkalinity and batch size. Overshooting the target and having to correct back down with pH Down wastes both products, so patience during the first few additions pays off.

Can pH Up be used in soil as well as hydroponic reservoirs?

Yes, the correction happens in the water itself before it ever reaches the root zone, so it works the same way whether that water is going into a reservoir, a coco feed, or a watering can for soil containers. Target ranges differ slightly by medium, so check the appropriate window for the specific growing method in use.

When during my feeding routine should I check and adjust pH?

Mix nutrients into the water first, then test and adjust pH last, right before the solution goes to the plant, since adding nutrients itself shifts pH. Checking pH before nutrients are mixed in gives a reading that won't match what the plant actually receives.

Is it safe to store pH Up alongside other nutrient additives?

Yes, store it sealed in a cool, dry location away from direct sunlight and away from acidic products like pH Down to avoid any cap cross-contamination. Keeping bottles tightly closed between uses also prevents evaporation from concentrating the solution over time.
