Hy-Gen pH Complete Control Kit - 150ML pH Up & Down | pH Indicator Kit
Regular price $25.00 Save $-25.00
- In hydroponics "pH" is an extremely important factor. When it is poorly monitored or controlled, plants can become sick or die. It is therefore recommended that pH is tested daily. Hy-Gen pH Up and Hy-Gen pH Down provide the grower with an added control in maintaining optimum pH levels and hence maximizing nutrient availability and plant productivity. A too high or too low pH can complicate the absorption of important nutrients such as iron, calcium, magnesium, etc.
- Generally the pH of the hydroponic solution should be 6.3. It is acceptable, however, to maintain the pH in the range of 6.0 to 6.5. For rockwool a lower pH of 5.8 to 6.0 is recommended. This allows for optimum nutrient solubility and availability.
HY-GENÂź COMPLETE pH KIT is an easy and accurate way to keep track of the nutrient solution pH. The kit gives the added ability to adjust your pH using the pH UP and pH DOWN solutions provided. Adjusting the pH is quite easy and after some time and experience it becomes an art as you start to learn more about your plants and growing system.
The concentrated indicator solution allows you to obtain a reading by using just one drop in the test tube provided. The calibrated colour chart provided helps test your pH to within 0.5 of a pH unit. Testing and adjusting your nutrient solution regularly will ensure your plants are healthy and happy.
Testing and adjusting the nutrient solution pH is made easy with a HY-GEN Complete pH Kit. The kit comes supplied with a test tube, 1mL transfer pipette, 150mL pH Up, 150mL pH Down, colour chart and concentrated indicator solution. Testing only requires one drop of indicator.
- Simple To Use
- Accurate Colour Chart
- Concentrated Indicator Solution
- Only One Drop Required
- pH Up And Down Solution
- Multiple Tests
- Transfer Pipette For Easy Use

FlairForm pH Electrode Storage - 250ML | Ideal for Bluelab & Other pH Meters
Regular price $10.00 Save $-10.00
Dry storage of pH electrodes is the most common cause of pH meter failure in hydroponics!
âpH electrodes last several years when stored properlyâ
pH electrodes should be stored in a specialized solution when not in use. This helps prevent dehydration of the glass electrode and porous frit (or wick) while preserving the electrodeâs filling solution.   pH buffers and distilled water are not suitable for storing pH electrodes as they can upset electrode calibration. Electrode storage solutions are carefully structured formulations that do not interfere with the chemical composition of the liquid/gel that is contained within the electrode.
Flairformâs pH Electrode Storage helps:
- Maintain electrode accuracy and response time.
- Eliminate reading âdriftâ.
- Maximize electrode life-span.

FlairForm Electrode Cleaner - 250ML | Ideal for Bluelab & Other Nutrient Meters
Regular price $10.00 Save $-10.00
For pH & conductivity electrodes
"We have not needed to re-calibrate our pH meters for over 3 years!"
Analytical Laboratory
In many situations, Flairformâs electrode cleaner eliminates the need to re-calibrate. Electrode cleaners are usually made from acids, alkalis or chelates. However, these chemicals are largely ineffective for cleaning electrodes that have been contaminated by nutrient solutions.
Flairform Electrode Cleaner is:
- Suitable for both pH & conductivity meter electrodes.
- Removes both inorganic and organic contamination.
- Restores electrode accuracy and response time.
- Maximizes electrode life-span.
- Unlike with other cleaners, the electrode does not require ârestâ time after being cleaned.
- Easy to use:Â Soak electrode for 5 minutes.

FlairForm pH Buffer 4.0 - 250ML / 1L | Calibration Solution for pH Meters
Regular price $10.00 Save $-10.00
pH meters must be regularly 'calibrated' (i.e. adjusted for accuracy) using standard pH buffer solutions which are made to an internationally agreed recipe.
- Flairform's buffers are formulated with NIST specified ingredients.
- Stabilised to resist algae or growth formation:Â Growths' can contaminate pH electrodes which in turn affects the âslopeâ value beyond the softwareâs ability to compensate.

FlairForm pH Buffer 7.0 - 250ML / 1L | Calibration Solution for pH Meters

FlairForm pH Test Kit - Sufficient for over 800 Tests | Fast pH Readings
Regular price $15.00 Save $-15.00
pH Dropper â Test Kit
For reliable & fast pH readings
âUnlike electronic pH meters, there is NO complex or costly maintenance required with the pH Test Kitâ
Super concentrated â ONE drop per test â approximately 800 tests.
pH range 4.0 to 8.0:Â Many pH testers do not operate below pH 6 (See pH Control).
Produces fast pH readings:Â Note that pH meter electrodes usually need to be left in the sample for several minutes before an accurate/ stable reading is produced.
Waterproof colour chart on side of bottle.
Perfect back-up for die-hard pH meter users.
Supplied with sturdy test tube.
How accurate is Flairformâs pH Test Kit?
When using a pH Test Kit, you will get accurate results every time. Even if electronic pH meters are properly maintained, they are still susceptible to error because lower quality electrodes respond to foreign âspeciesâ (e.g. sodium). For this reason, if using an electronic pH meter, occasionally cross check your readings with a pH Test Kit.

Hy-Gen pH Buffer - 250ML | 7.0 | Calibration Solution for pH Meter
Regular price $10.00 Save $-10.00
pH BUFFER 7 is important as the upper calibration point in the two pointâ calibration of electronic meters. Regularly calibrate your pH meter with both pH BUFFER 4 and
pH BUFFER 7 calibration solutions to ensure that your meter is operating with precision and accuracy between pH 4 and 7.
Monitor the pH on a daily basis. As plants grow, demand for nutrients increase. This means the pH can fluctuate and therefore should be tested and adjusted to maintain an optimum working nutrient solution. Nutrient requirements vary from plant to plant; therefore the ideal pH varies from plant to plant also.
SOLUTIONS SCIENTISTS USE
HY-GENÂź Calibrations solutions are made according to international standards. The pH ELECTRODE STORAGE and PROBE CLEANER solutions are the same quality as those used in laboratories for the safe cleaning and storage of electronic meters. All calibration and care solutions are made using high quality analytical grade constituents.

House & Garden pH Stabiliser - 1L | Eliminates pH Fluctuation |Stabil Osmose
Regular price $50.00 Save $-50.00
House & Garden pH Stabiliser has been developed in order to balance the pH in the growth cycle of the plant and will keep the pH balanced for up to 10 days. House & Garden pH Stabiliser will harmonise with the base nutrient and enable good absorption of the main and trace nutrients by the plants.
A correct pH value leads to better absorption of the main and trace elements. Therefore, maintaining a correct pH value results in better growth and higher yields.
- Dilution rates of pH Stabiliser is 1ml/L
APPLICATION
- Use pH Stabiliser throughout the entire growth cycle.
- Prepare your nutrient container by first adding your pH Stabiliser before adding any base nutrient (e.g Cocos, Hydro or Soil) to the water container. Adjust your EC of the nutrient and then add your Stimulants and Additives. Adjust the pH value to harmonise with the nutrient solution.
