How do you read a truncheon?
To take your first reading, follow these steps.
- Remove the Truncheon from the packaging and ensure the shroud is fitted.
- Submerge the probe head into your solution.
- Wait 10 seconds or so for the thermistor to come to solution temperature.
- Read the measurement displayed by the blinking LEDs.
Does the bluelab truncheon measure pH?
When you combine this pen with Bluelab’s Truncheon Nutrient Meter, you’ll be able to measure conductivity, temperature and pH, which not only enables you to actively manage your nutrient levels but also ensures that your plants have access to the food they need.
What meters do I need for hydroponics?
A TDS meter is a crucial tool that every hydroponic gardener should have access to and know how to use. Without using a TDS meter regularly, growing crops hydroponically is a serious gamble.
What is the perfect PPM for hydroponics?
between 800 to 1500 parts per million
As plants consume nutrients and water, the nutrient strength in the hydroponic reservoir will change. GENERALLY, nutrient strength should run between 800 to 1500 parts per million (ppm).
How many PPM is a tomato?
Recommendations for protected cultivation of tomatoes in the soil are 134-145 ppm N, 16 ppm P, 176-243 ppm K, 49-65 ppm S, 60-90 ppm Ca and 32-36 ppm Mg. Micronutrients like iron (280 ppb or mg/1000 liter), manganese (110 ppb), zinc (65 ppb) and boron (110 ppb) are also important.
What’s the difference between ppm and EC?
The most common are Electro Conductivity (EC) and Parts Per Million (PPM). EC is the best way to display the TDS of a nutrient solution because it is a universal unit. Unlike PPM which is EC x 0.5 or EC x 0.7.
What pH should my hydroponic water be?
between 6 to 6.5
Nutrient solutions used for soilless culture should have a pH between 5 to 6 (usually 5.5), so the pH in the root environment is maintained between 6 to 6.5. This is the pH range at which nutrients are most readily available to plants.
Is PPM the same as pH?
pH refers to the potential of hydrogen ions in your water, which will determine if your water is too acidic or has too much alkaline in it. PPM (parts per million) refers to the concentration of minerals and soluble matter in your watering solution.
What is the ideal EC for tomatoes?
Electrical conductivity (EC), measured in milliMhos, is the measure of electrical conductance of the total dissolved solutes (minerals) in the solution. The optimum EC range for tomatoes is 2.0 to 3.5 milliMhos.
What is the best ppm for tomatoes?
Growing a Variety of Fruits and Vegetables with Hydroponics
| Plant | pH | PPM |
|---|---|---|
| Tomato | 5.5-6.5 | 1400-3500 |
| Watercress | 6.5-6.8 | 280-1260 |
| Watermelon | 5.8 | 1050-1680 |
| Zucchini | 6.0 | 1260-1680 |
What should my EC be in veg?
1.2-1.6
During the vegetative growth stage, it’s best to keep the EC in the 1.2-1.6 range for most plants. If the EC rises above 1.8 during the vegetative growth stage, just add more water to the reservoir to lower the EC. If the EC is too low, just add more fertilizer.
How do I use the truncheon meter?
For the Truncheon Commercial, if the measurement is between two points the lights will blink more frequently closest to the measurement. Tip: Besides being used to measure nutrient levels, the Truncheon Meter can also be used to mix your nutrients into your solution.

How do I use the truncheon thermistor?
Remove the Truncheon from the packaging and ensure the shroud is fitted. (The shroud must be present as readings taken without it will be inaccurate.) 2: Submerge the probe head into your solution. 3: Wait 10 seconds or so for the thermistor to come to solution temperature.
Why do I need the truncheon?
