What is Total Dissolved Solids (TDS)?
TDS stands for Total Dissolved Solids. It refers to the combined content of all inorganic and organic substances dissolved in water, including minerals, salts and nutrients. In hydroponics, measuring TDS using a TDS meter helps determine if the nutrient solution is at the right strength. Too high orRead more
TDS stands for Total Dissolved Solids. It refers to the combined content of all inorganic and organic substances dissolved in water, including minerals, salts and nutrients. In hydroponics, measuring TDS using a TDS meter helps determine if the nutrient solution is at the right strength. Too high or low TDS can affect plant health. Balanced TDS ensures optimal nutrient absorption and supports healthy, steady growth in hydroponic systems.

In the Deep Water Culture (DWC) system, roots are fully immersed in water, which can run out of oxygen. So, an air pump or aerator is needed to provide oxygen for root health. In the Nutrient Film Technique (NFT), a thin stream of water flows continuously over the roots, naturally carrying dissolvedRead more
In the Deep Water Culture (DWC) system, roots are fully immersed in water, which can run out of oxygen. So, an air pump or aerator is needed to provide oxygen for root health. In the Nutrient Film Technique (NFT), a thin stream of water flows continuously over the roots, naturally carrying dissolved oxygen. Thus, NFT doesn’t need an aerator because its water movement keeps roots aerated and healthy.
See lessOxygen is required for healthy root growth. Explain.
Plant roots need oxygen for respiration, which helps absorb nutrients and release energy. In soil, air naturally surrounds roots, but in water, oxygen must be provided. In hydroponics, aerators or flowing water systems (like DWC or NFT) ensure roots don’t suffocate. Without enough oxygen, roots turnRead more
Plant roots need oxygen for respiration, which helps absorb nutrients and release energy. In soil, air naturally surrounds roots, but in water, oxygen must be provided. In hydroponics, aerators or flowing water systems (like DWC or NFT) ensure roots don’t suffocate. Without enough oxygen, roots turn brown, rot and plants become weak. Supplying air to water is essential for healthy, fast-growing hydroponic plants with strong roots.

Capillary action is the process where liquid moves through narrow spaces or tubes due to surface tension and adhesive forces, even against gravity. In hydroponics, this principle is used in the wick method. A cotton wick pulls nutrient-rich water from the container below into the growing medium. ThiRead more
Capillary action is the process where liquid moves through narrow spaces or tubes due to surface tension and adhesive forces, even against gravity. In hydroponics, this principle is used in the wick method. A cotton wick pulls nutrient-rich water from the container below into the growing medium. This helps deliver moisture to plant roots steadily, without the need for any pumps or power, making it perfect for simple systems.

For the hydroponic setup, I selected seeds like mustard, spinach, fenugreek and coriander. These are fast-growing, easy to manage and ideal for beginners. They sprouted well on jute mats or coco peat with regular watering. Their roots quickly adapted to the water-based environment. These microgreensRead more
For the hydroponic setup, I selected seeds like mustard, spinach, fenugreek and coriander. These are fast-growing, easy to manage and ideal for beginners. They sprouted well on jute mats or coco peat with regular watering. Their roots quickly adapted to the water-based environment. These microgreens are ready in 7 to 10 days and provide essential nutrients, making them a great choice for fresh, healthy homegrown greens.
