Target pH: 5.5 – 6.5
Stop using chemical buffers! Prevent pH swings in hydro with a Torus Hydro PerfectpH.
It’s a smart pH stabiliser. It helps prevent your pH changing as plants use nutrients.
To work, your feed will need to be in contact with your perfectpH as plants feed, or between feeds (e.g. in recirculating systems)
Use it to keeps your pH in the right range for optimum nutrient absorption, using ionisation technology.
It’s easy to use – no programming is needed. Simply place it in your tank and it works instantly. Make sure you recharge it every 3 - 4 months with perfectpH Recharge Solution though!
- Prevent nutrient lockout caused by big pH swings
- Increase nutrient absorption with an optimum pH
- No more chemical buffers
- No programming needed – works automatically
- 90 day manufacturer’s warranty
- Recharge every 2 - 4 months using PerfectpH Recharge Solution
How it Works
As nutrients are used by plants, your pH can slowly drift up and down.
This is caused by the plant spitting out excess ions such as hydrogen (H+) and hydroxide (OH-). These affect the pH of the nutrient solution.
- An increase in H+ ions causes the pH to drop (become more acidic)
- An increase in the OH- ions causes the pH to rise (become more alkaline)
Positively charged ions (like H+) like to attach themselves to negatively charge ions, like carbonates, bicarbonates, silicates and hydroxides (OH).
So, the amount of these negative ions in the solution affects the ability of the solution to neutralise positively charged ions and keep the solution at a stable pH. This is known as the alkalinity of the solution.
When a plant is kicking out an excess of H+ ions, the carbonate present grabs on to them and stops them from affecting the pH. It gets to a point when all negative ions are used up. The buffering stops and the pH will drift dramatically.
Torus Hydro PerfectpH reduces positively charged ions such as H+. This prevents naturally occurring negative ion, which buffer the solution, being consumed. This helps keep your pH within the perfect range.
Why Monitor your pH?
At the wrong pH, some nutrients precipitate out of your solution and change form. This is where they sit in your feeds as solids. Some will actually bind to other nutrients, altering their charge and state but remain in the solution.
When this happens, they can no longer be absorbed by plants. This causes nutrient lockout. As plants use nutrients, your pH can drift. When this happens, plants will end up absorbing too much of some nutrients and not enough of others.
To maximise nutrient uptake, keep your pH within a safe range. For most plants, that’ll be somewhere between 5.5 – 6.5.
How to Use
- Keep PerfectpH in its protective case
- Store at no more than 50oC
- To use, place the perfectPH in your nutrient tank and let it stabilize the pH
Make sure that your nutrient solution comes into contact with your perfectpH during feeds or between feeds. If it's not in contact with your nutrient solution as plants feed, it can't stop your pH changing.
To keep your perfectpH working at its best, recharge it every 3 - 4 months.
Remove perfectpH from your reservoir and submerege it in the perfectpH Recharge Solution. This releases the build up of H+ ions that the perfectpH captures.
Note: We don’t recommend using hydrogen peroxide products when using perfectpH
