ph & EC: Aqua Master Meters

Aqua Master Tools offer a range of quality pH, EC and temperature meters for measuring nutrient solution.

Ian has interviewed Pim van Seventer, Sales Manager at Aqua Master Tools, in a series of in-depth videos covering the range of Aqua Master products and what the future has in store.

Watch the video to learn about the Aqua Master brand and the latest innovations.

The Importance of Understanding pH when Growing

pH refers to the measurement of acidity or alkalinity. The pH scale ranges from 0 to 14, with 7 being neutral. A substrate or nutrient solution with a pH below 7 is considered acidic, while a pH above 7 is considered alkaline or basic.

The pH of your media or nutrient can have a substantial effect on plant growth and nutrient availability. Different plants have different preferences for pH. If the pH is outside of the optimal range, some nutrients may become unavailable to plants, even if they are present in the media.

By measuring the pH of your substrates & nutrient solution, you’re able to identify if any amendments are required to adjust the pH to within an appropriate range

Know Your EC When Growing

EC (Electrical Conductivity) is the measurement of the substrates / nutrients ability to conduct an electrical current and indicates the concentration of soluble salts within them. The higher the concentration of soluble salts, the higher the electrical conductivity of your media or nutrient solution.

High levels of soluble salts can be harmful to plants, as they can affect water uptake and cause toxicity issues. Equally, low levels of soluble salts can suggest poor substrate fertility, which can also impact plant growth.

The top 3 reasons why you should measure EC and pH?

1. Nutrient Availability – EC and pH levels affect the availability of nutrients in your media. Different nutrients are available at different pH ranges (lockout), and the electrical conductivity (EC) of the substrate can indicate the presence of certain nutrients. For example, high levels of EC can indicate a high concentration of nutrients like potassium, calcium, and magnesium, while low levels may indicate a lack of these nutrients.
2. Plant Growth – EC and pH levels also affect plant growth. pH can impact the uptake of nutrients by plants, and certain plants grow best in specific pH ranges. Additionally, high levels of EC can be harmful to plants, as they can cause root damage and reduce water uptake.
3. Substrate Health – Measuring EC and pH levels can provide insight into the overall health of the substrate you are using, a balanced pH and nutrient levels will support healthy microbial activity, which in turn helps to maintain substrate structure and promote plant growth.
