Save Time + Save Money + Increase Yields

The PerfectpH is the first tool of it's kind, designed to keep pH automatically balanced in hydroponic growing, as well as increase yields and reduce frequency of necessary reservoir changes.

What It Does

Automatic pH Maintenance

PerfectpH keeps pH automatically balanced so plants are safe from harmful pH swings. No more daily pH checks or chemical additions, set your pH as preferred and PerfectpH maintains it in this range.

Less Reservoir Changes

Using PerfectpH, the overall health of the reservoir stays better maintained and balanced. This safely allows for less frequent reservoir changes, saving time, labor, water and nutrients.

Increased Yields

Though required in a typical system to maintain pH, adding pH up/down chemicals block plants from best absorbing nutrients, limiting potential growth and wasting nutrients. By maintaining pH without frequently adding chemicals, the nutrients are used more efficiently and yields are increased.


How It Saves Money

• The PerfectpH recharges every 2-4 months for repeated uses, by a simple rinse in PerfectpH Recharge Solution.

• Each bottle of Recharge Solution comes with enough fluid for multiple recharges, so recharging is cost efficient and allows many growers to save money compared to pH up/down chemicals.

• If using a larger model size than required for your system, PerfectpH will last even more time before requiring a recharge.

What Growers Around The World Say

Since 2017 Torus Hydro has been delivering solutions to make hydroponics easier, simpler, and more sustainable for growers across the globe. Today the PerfectpH has users in the US, UK, Canada, Australia, New Zealand, Spain, France, Germany, Sweden, Russia, Switzerland, Singapore, Chile and more. See what growers around the world have to say:


How It Works

Using ion technology, the PerfectpH attracts and captures the charged particles that influence pH, targeting pH problems at their source and keeping pH in the ideal range for proper growth.

PH is a measurement of charged-hydrogen concentration, and as this concentration changes growers then see spikes or drops in their pH value. What growers are actually witnessing is an excess of positive (H+) or negative (OH-) hydrogen ions building up, which then inhibit the plants from properly absorbing the nutrients they need. Without the PerfectpH, this then requires growers to keep constant attention to make sure that the pH is maintained in the proper range.

The charts below represent a recirculating hydroponic system, where the plants themselves alter this hydrogen ion-concentration by releasing hydrogen ions into the water/nutrient mixture as they grow:

Excess H+/OH- ions build up in the system during photosynthesis, causing pH fluctuation, blocking nutrients from proper absorption, weakening the plants’ immune systems and diminishing yields.

With the PerfectpH, excess H+/OH- ions are attracted and captured from the system, creating a balanced pH, a healthy reservoir environment and greater nutrient-use efficiency, resulting in healthy plants and great harvests.

The PerfectpH acts as an outlet for these ions, capturing ions that would otherwise raise or lower pH outside of the ideal range. Simply drop the PerfectpH capsule model into your reservoir or connect the PerfectpH Inline Edition to your pump, no power required.


Common Questions

What pH value does PerfectpH maintain?

The PerfectpH maintains pH at least within 5.7–6.3 pH, depending on the set-up/plant type/feeding/stage of growth, allowing for slight fluctuation within this range for best nutrient absorption. For most systems, the pH will be maintained between 5.8-6.2.

Does it do anything else?

Yes actually! In addition to balancing pHPerfectpH maintains the ionic balance of your reservoir, allowing for more efficient nutrient absorption and less frequent reservoir changes. Some of our growers go full harvests just topping their reservoir up without problem. We recommend a res change around every 4 weeks for most setups.

How do I recharge it, and how often?

To recharge, remove the PerfectpH from use and submerge the capsule model in (or fill the Inline Edition model with) PerfetpH Recharge Solution liquid for about 2 hours.

Rinse the unit with water and return to use. We recommend a recharge every 2-4 months for best use, but a larger model can be used for your system to extend this time even further.

How does the maintenance cost compare to using pH up/down?

We sought with the PerfectpH to not only make pH maintenance easy but also affordable. Though the initial cost of a PerfectpH is more than buying a bottle of pH up or down, for many growers the maintenance cost in PerfectpH Recharge Solution costs less than frequently using pH up/down chemicals, for some significantly less, with much less labor required.

Why did we create PerfectpH?

Coming with several years of growing experience and a love for the art and science of hydroponics, we’re a team of growers based out of California, who became frustrated with pH problems and the time requirement of frequently checking pH and adding up/down chemicals. We felt there had to be a better way.

We sought out a way to solve this, and after several years of research and development the PerfectpH was born. We felt that there must be other growers who felt how we did too, so we decided to create Torus Hydro to provide growers around the world the freedom and ease of hydroponics without pH worries.

Can I use it in a non-recirculating system? Or a gravity-feed tank?

Yes, the PerfectpH can be used to maintain balanced pH in a reservoir tank (also known as a pre-treatment tank or holding tank), which can then be used with a drain-to-waste / drain-to-use / drip-to-waste / drip-to-use system, or can also be used for non-hydroponic soil cultivation. This tank can be used as a source to hand-water plants, or to pump-feed or gravity feed the system.

To use the PerfectpH like this, connect the PerfectpH Inline Edition to a pump and place inside the tank. This will then circulate the water/nutrient mix through the PerfectpH, treating the mixture and resulting in a balanced pH and a healthy reservoir environment. The diagram below represents this type of use:

Is the PerfectpH right for my grow?

It depends on the specifications of your exact grow, but we offer several different PerfectpH models to work for many different types and sizes of grow set-ups. Use the Product Selector to learn more and find the model right for you.
