NutriHydro pH Control Solutions

Foliage grown at the correct pH exhibit peak health possible for a crop

Quality is in the Details

pH control is necessary for the quality of your crops. A well managed pH will show the highest quality possible you can  achieve. In fact, a crop grown at the correct pH will show very healthy foliage if you look at it up close.

NutriHydro manufactures pH control solutions for use in hydroponics, aeroponics, aquaponics, seedling production, and soil conditioning.

NutriHydro pH Up
Control Solution

pH Up is a mineral based pH adjuster using potassium at the core of its component. Mineral based pH control is the most stable form of pH control thus eliminating the need for constant re-adjustments once the control additive has combined with the base solution. NutriHydro’s pH Up is a widely used pH control solution in the country and commonly used by commercial greenhouses and enthusiasts due to its known effectivity.

NutriHydro pH Down
Control Solution

NutriHydro’s pH Down comes in two variants. Nitrogen based and phosphorus based.  Nitrogen based pH down is usually used for seedling production and for foliage crops. Nitrogen based pH down produces healthier seedlings which lead to better overall yield.

Phosphorus based pH down is usually used for general crops and is the more common acidifying solution. Phosphorus based pH down is  preferred for use by growers when they require crops to flower, bloom, or fruit.

Agriculture Reputation

NutriHydro's pH Control Solutions are stable and therefore can be relied upon to deliver consistent results

Mineral Based Consistency

Mineral based pH control solutions perform stable and consistent. It is perfect for use in a commercial setting and for use of those who will eventually go professional growing.

What is pH all about and why is it important?

NutriHydro's nitrogen based pH down works great in seedling production. Many commercial greenhouses who have discovered the use of nitrogen based pH have yielded healthier seedlings of foliage type.

Pro-Growers Tips

use of tds meters

For users who want to ensure maximum yield from lettuce crops, it is recommended to use a TDS meter. TDS is short for Total Dissolved Sediments Meter. It is used as it is called, to measure total dissolved sediments in water. Doing so gives you a guide n how much nutrient solution is in the water. It is recommended that you use a TDS meter so you can measure objectively and eliminate guess work.

use of ph testers

It is a must to use a PH meter. Lettuce needs water with NutriHydro Letttuce Formula to read between 5.5pH to 6pH. Going below 5.5pH will lead to macronutrient deficiency (NPK deficiency) and stunted growth. Going beyond 6pH will lead to micronutrient deficiency (trace element deficiency) which leads to burnt tips and causing the crop to turn yellow and lose its health. As it is so said in hydroponics, “pH is the key”. Once you have tested your pH, you will need NutriHydro pH Adjuster to dial down your pH to the correct range.


Most frequent questions and answers

The pH level of a liquid solution tells us how acidic or alkaline it is on a scale from 0 to 14, with 7.0 indicating a pH-neutral solution. From this neutral midpoint, the solution becomes increasingly acidic as the pH approaches zero and increasingly alkaline as the pH approaches 14. Pure water is pH neutral.

When you look at the chemistry behind pH, as you probably know, water molecules consist of two hydrogen atoms and one oxygen atom (H2O). But when a compound dissolves in water and produces free ions (atoms or molecules with an electrical charge), it can cause some of the water molecules to split apart, creating positively charged ions (H+) and negative charged hydroxide ions (OH-).

The pH of a solution indicates the concentration of free hydrogen ions it contains. Pure water has equal concentrations of H+ and OH-, while acidic solutions have higher concentrations of H+ than OH- and alkaline solutions have the reverse. These characteristics at the molecular level are responsible for the sour and corrosive properties of acid solutions and the bitter, slippery nature of alkaline solutions.

A pH value is a scale measurement, meaning that each whole number represents a tenfold difference in the concentration of hydrogen ions, and therefore, a tenfold difference in the strength of the acidity or alkalinity.

In soil based planting, plant roots absorb nutrients dissolved in water which originate from organic and inorganic compounds in the soil. Microorganisms and organic matter play a role in the formation and fertility of the soil, while interactions of minerals and water fluctuations in pH levels naturally control soil’s pH. Plants that grow in these soils have evolved and adapted themselves to take advantage of these controlled soil pH levels. Hydroponic growers are solely responsible for recreating the ideal environments that encourage plant roots to absorb vital nutrients.

Whichever type of hydroponic system you are using, the goal is to always deliver water and nutrients to the roots of plants via a water-based nutrient solution. And while it’s crucial that you deliver a consistent supply of the nutrients that are appropriate for the types of plants you are growing, it’s also vitally important that you provide the proper pH levels for nutrient uptake.

Monitoring and adjusting pH in hydroponics ensures the nutrient availability of your solution. Subsequently, if your nutrient solution doesn’t have the correct pH, you risk starving your plants – even though you are providing them with plenty of nutrients.
