Hydroponics
• Hydroponics : Hydro = Water , Ponics = work
Hydroponics is growing plants in inert medium like coco-peat, Perlite, vermiculite and providing essential nutrients through water i.e. Nutrient solution.
• Inert material means it does not provide nutrition.
• Unlike soil which provide various nutrients to plants.
Why hydroponics?
• Water scarcity at certain location.
• Labour availability problems or labour cost.
• Undulating land. Tillage not possible with tractor/bullocks
• Soil is not cultivable (Barren Sodic soils-Kutchh).
• Automation of cultivation for efficiency.
• Cultivation on Roof top – terrace gardening or urban farming.
• Recreation/hobby like Living wall.
Sloppy, uneven and rocky land
Benefits of Hydroponics
• Efficient use of water and fertilizer. Reduces water consumption by around 80-90 %.
• Better and efficient control on macro and micro nutrients application.
• Recycling of water is possible.• Reduced labor cost on land preparation, compost
, fumigation and inter-culture – removing weeds.• Better control on EC & PH.• Efficient control on soil borne diseases like root
rot.• Better quality, shelf life and Productivity.
Myths and reality
Myth - Hydroponics should be done in polyhouse only.
Reality –NOIt can be done in shade net / open cultivation.
Myth-It uses harmful chemicals.
Reality –NoIt uses pure water soluble fertilizers.
Myth-Only For Salads
Reality:No It can use used for all vegetables

Methods
SUB IRRIGATED : watering from bottom1. DWC – Deep water culture2. Wick Method3. Aeroponics4. Ebb and Flow5. NFT – Nutrient film technique.
TOP IRRIGATED : watering from top
Drip method
Material required
• Substrates.
• Nutrient solution.
• Drip irrigation/grow trays/NFT/grow bags/pots.
• Mulching- Polythene mulching paper/ground net.
Substrates.
• Substrates provide support to roots and holds nutrients solution.
• Coco peat – Obtained from coconut husk.
• Vermiculite – Treated mineral
• Perlite –Treated mineral.
• Sand/pine bark etc.
Fertigation
• Water quality– Water PH. management
– EC – Electrical conductivity. management
– EC of substrate. Management
Nutrient solution Fertilizers: Macro and Micro Nutrient
Use two separate tanks: Tank A and Tank B
These tanks has the macro and micro nutrients solution which is scientifically designed for its right combination and proportion.

Costing
Infra structure cost
• Small grow bag 30-35 rs
• Long grow bag : 80-100 rs.
• 3 year life of each grow bag
• Drip irrigation : 40 000 per acre
Operation cost : Fertilizer cost 15000 to 40000 for 10 gunthe
Savings : no Weeds, Reduced labour, no soil born diseases/ pests, water 80-90% saving
Grow bags arrangement method
Single grow bag arrangement
big grow bag arrangement 2 bags row
big grow bag arrangement 1 bags row
Costing Example
• Data– Crop Zucchini– Plant to plat distance 3 feet– Row to row distance 2 feet– Walking path between rows 2 feet
• Calculation– Since distance between plant is high use single grow
bag– 100 feet x 100 feet L x W = 10000 sq feet area– In one row place 33 grow bags at distance of 3 feet
centre to centre– You can make 50 columns– 33 x 50 = 1650 grow bags (small size)– Price per frow bag 30, 1650 x 30 = 49500
