The two main measurements a hydroponic grower needs to make are pH and EC levels. Both of these can be done with meters. pH is the measure of the acidity of a system and determines how plants and other organisms interact with different nutrients.

How do I test my hydroponic nutrients?
Use a TDS/PPM or EC meter to check the strength of your nutrient solution. If it is too strong, add water. If it is too weak, add a little fertilizer. [See Warnings] Make sure you re-test the pH after making changes.
How do you measure nutrients in water?
To measure the level of nutrients in water (or any solution) you need a so called EC/TDS meter to measure EC level.
How do you test hydroponic water?
In a hydroponic system, you have direct control over the nutrients that you provide to your plants. There are three key variables you want to test for in your water: pH, conductivity (EC), and temperature.
- pH. pH is a measure of acidity in the water.
Do I need a TDS meter for hydroponics?
Every hydroponic grower should have an EC/TDS meter. This takes the guesswork out of the critical process of feeding your plants.
What is the correct EC for hydroponics?
For most hydroponic crops, the ideal range of EC for most crops is between 1.5 and 2.5 dS/m. A higher EC could prevent the plant from absorbing nutrients due to increased (more negative) osmotic pressure, and EC levels that are too low could adversely impact yield.
How often do I add nutrients to my hydroponics?
Every 7-10 days is recommended. A small amount of nutrient in the flush solution (EC 0.6 ) will save the plant from any unnecessary stress. Make sure temperature and pH of flush water is correct. Do not over flush as this can cause inconsistent PPM/EC/CF levels!
Is EC the same as PPM?
Summary. ppm stands for parts per million & is the most common domestically used unit when measuring TDS. EC stands for electrical conductivity, which is a measurement of the ability of something to conduct electricity. In horticulture, EC is the most accurate way to measure nutrient concentration in solution.
What is the best fertilizer for hydroponics?

Is EC the same as TDS?
Total Dissolved Solids (TDS) and Electrical Conductivity (EC) are two separate parameters. TDS, in layman’s terms, is the combined total of solids dissolved in water. EC is the ability of something to conduct electricity (in this case, water’s ability to conduct electricity). That’s TDS!
How often should hydroponic water be changed?
Full Water Changes The best time to change your hydroponic water entirely is after you’ve topped it off enough times to fill it fully. For an average-size hydroponic system, you’ll likely need to change your water every two to three weeks.
What causes pH to rise in hydroponics?
Several factors can cause pH levels to change in hydroponic systems. When the amount of the nutrient solution drops below one gallon, the solution becomes more concentrated as plants absorb the nutrients. As algae consume acidic carbon dioxide during the day, pH levels rise and then fall by evening.
What is the best TDS for hydroponics?
The ideal TDS reading for plants grown hydroponically varies from around 500 or 600 on up to well over 1,000. That said, we suggest sticking with a TDS level of around 800. Leafy greens, like lettuce and spinach, for example, require a TDS level of around 550 to 850, much lower than the 1,200-plus that bok-choy needs.
What is the best ppm for hydroponics?
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).
Is TDS the same as PPM?
Total dissolved solids (TDS) is measured as a volume of water with the unit milligrams per liter (mg/L), otherwise known as parts per million (ppm). For example, if a TDS meter says 100 ppm, that means that from one million particles, 100 are dissolved ions and 999,900 are water molecules.
