Answer: Total Dissolved Solids (TDS) is a measure of the combined content of all the inorganic and organic substances such as mobile charged ions, minerals, salts or dissolved metals in a volume of liquid. Normally TDS is used in water testing, where TDS is defined as anything present that is not pure water (H2O) molecule or suspended solids. Finding out the exact amount of TDS in water ...

What is hydroponics?
"A technique of growing plants in nutrient solution”. Hydroponics literally means water-working or water-activation. It is a cultivation technique for growing plants in highly oxygenated, nutrient enriched water, rather than soil.
The nutrient solution and its mana...
