Description
An easy-to-use meter for those who want to keep track of their crops.
What is the pH of your water, how many nutrients are left in the water, and what is the temperature of the water?
If you have problems that you don't understand the cause of or want to maximize your results, this meter is worth its weight in gold. The Swedish manual includes a list of values that different crops thrive best in.
The correct pH value is important for your plants to feel good and absorb nutrients in the best way.
The EC value shows how much nutrient is in the water. Some plants are hungrier than others and consume more nutrients than water, and some become overfed if you add the same amount of nutrients each time. With this meter you don't have to guess.
Most often there is more water than nutrients, which means that the concentration of nutrients increases as the water level decreases. A vessel filled with water and a value of 800 for nutrients, may well be over 1100 a few weeks later if half of the water has been used up.
When growing hydroponically, it is important to keep track of the EC value, especially how it changes. The EC meter is a way to measure how much nutrients and water your plants are taking up. If you have an EC starting value, you can check after 1-2 days how much nutrition and water your plants are drinking. If the EC value drops, the plants are drinking more nutrition than water and then you need to add more nutrition. If the EC value rises after 1-2 days, the plants need more water.
Also keep an eye on the color of the leaves. If the plant turns dark green and the leaves become burnt at the ends, it is a sign of too much nutrition (too high an EC value) and you need to add more water.
If the plants are too light in color, the cause is often too little nutrition (too low EC). Is the pH value correct? (too high or low prevents the plant from absorbing nutrition) then add more nutrition.
The neutral PH value is 7.0. Most plants thrive best between 5.2-6.5.
| Crop | Ideal pH value |
|---|---|
| Salad | 5.5-6.5 |
| Tomato | 5.5-6.5 |
| Cucumber | 5.8-6.0 |
| Pepper | 5.8-6.2 |
| Basil | 5.5-6.5 |
| Strawberries | 5.5-6.5 |
| Broccoli | 5.5-6.5 |
| Cabbage | 5.5-6.5 |
With a meter you don't have to guess and can understand if it's not growing properly.
It comes with three bags of Buffer Powder. With these you can easily mix into calibration fluid to calibrate your meter. If you need more calibration fluid, you can buy more bags here
