Hydroponics Soil-less Farming Guide: System & Setup

What is hydroponics?

A method of growing plants in water enriched with mineral nutrients, completely eliminating the need for soil.

What crops grow best in hydroponics?

Leafy greens (lettuce, spinach, kale), herbs (basil, coriander), tomatoes, cucumbers, strawberries, and bell peppers.

Why does hydroponics use less water than soil farming?

Water is recycled in a closed-loop system, preventing water loss due to soil absorption, runoff, and deep evaporation.

What is the NFT system in hydroponics?

Nutrient Film Technique is a system where a continuous, shallow stream of nutrient-rich water flows over the plant roots.

What pH level is ideal for hydroponic plants?

Most plants require a slightly acidic water environment, with an ideal pH range between 5.5 and 6.5.

What is EC in hydroponics?

Electrical Conductivity measures the concentration of dissolved mineral salts in the water, helping you gauge if your plants need more food.

Can I grow root vegetables like potatoes in hydroponics?

It is possible but difficult. Root crops require deep support structures and are usually grown in substrate systems rather than water channels.

Do hydroponic plants need sunlight?

Yes, they need light for photosynthesis. You can use natural greenhouse sunlight or install LED grow lights for indoor setups.

What is the startup cost of commercial hydroponics?

Commercial setup costs are high, ranging from ₹10 Lakhs to ₹25 Lakhs per acre, but yield rates and profits are significantly higher than traditional farming.

What is the role of coco peat in hydroponics?

Coco peat is used as a supportive, pH-neutral growing medium to hold seeds and roots in net pots before they reach water channels.
