Hydroponics & Gardening

TDS and pH meters are critical when growing plants by hydroponics.

Hydroponic gardeners all over the world monitor nutrient levels in roughly the same way—by measuring total dissolved solids in the growing solution — but they have different preferences for the format of their test results. Growers in the U.S. often examine a simple ratio known as parts per million PPM). High concentrations of salts increase the solution’s electrical conductivity (EC).

Total dissolved solids readings help to indicate the density of solution which can help to determine when it’s time to add nutrients. Temperature can affect TDS/EC meter readings. It is important that you read your hydroponics nutrient packaging carefully to make sure feeding indications correspond with your meter.
