Pre-calibrated and ready to use, this meter helps you feed your plants the right nutrients for healthier growth and prevents crop failure. Includes batteries and easy instructions.

    Features

    Why do I need a nutrient meter?

    Using a nutrient meter is the best way to accurately feed your plants the nutrients that they need. By accurately providing your plants with what they need, you'll notice faster and healther growth - you also will reduce the risk of your crop failiing due to having the wrong nutrient mix - which is the most common reason for failure in hydroponics!

    You'll find that as you test the EC (electrical conductivity) of your nutrient solution, over time you will learn a lot about how your plant consumes water and nutrients. For example in hot and dry conditions, plants typically consumer more water than nutrients (as a percentage), which means the nutrient concentration will go up, as there's less water but a similar amount of nutrients! The is an issue because when the nutrient concentration is too high, it will actually suck water out through the roots of the plant (through osmosis) in order to balance out salinity levels. On the other hand, in cool conditions a plant may rapidly consume nutrients, but not water - resulting in a lower nutrient concentration in the water. Of course this is an issue as the plants won't have enough nutrients to grow!

    Instructions

    Measuring EC is really easy once you're all set up, all you need to do to get an accurate reading is:

    1. Rinse the electrode on the EC meter
    2. Turn the meter on
    3. Immerse the meter electrode in the solution you want to test
    4. Stir gently and wait 30 seconds for the reading to stabilise.
    5. After reading, clear the electrode and turn off the meter. Always replace the protective cap after use.

    💡 Product Use & Care (Grow Lights)

    How do I use grow lights effectively?
    ▼
    Distance & Time: For most houseplants, place the light 30-60cm (12-24 inches) away and run for a 12–16 hour photoperiod. Seedlings and herbs may require the light closer (15-30cm). Using a timer is highly recommended for consistency.
