The word hydroponics been derived from the Green world "Water Working", is directed to growing plants without soil (Hydro means water and Ponic means working). Hydroponics is the science of soiless growing of plants in nutrient rich solutions. It is a technique where the physiological requirements of plants can be met without use of soil and natural sunlight. In conventional system, seed start germinating when it gets favorable conditions (like: Water, Air, Temperature and Light) maximum energy is utilized by the seed in search of nutrient by developing radical (roots), very less amount of energy is utilized for the growth of the plumule (shoot). In hydroponics, favourable conditions are provided to the seed and food is directly supplied to the plumule, so the maximum energy is utilized in the growth of the plumule rather than in developing radical in search of nutrient. Hydroponics techniques have proven itself to be very useful and efficient for producing food for livestock. The advantages of hydroponics agriculture include control over plant nutrition and therefore increased production, stable harvests of high quality fresh feeds which is available all the year and can be produced on an industrial scale; the food that is available is free from undesirable materials such as weeds, insects, dust, insecticides, germicides, carcinogens and radioactive substances. Hydroponics culture is probably the most intensive method of crop production in today's agricultural industry. With the possibility of adjusting air and root temperature, light, water, plant nutrition and adverse climate, hydroponics agriculture can be made highly productive, conservative of water and land and protective of the environment. With Ayurvet's ProGreen, uncontaminated, consistent and succulent green feed is available 365 days of the year regardless of location or weather. In Ayurvet's Hydroponics machine*, green feeds are grown in controlled environmental conditions with a temperature range of 15°C - 32°C and a relative humidity of 80-85%. Green feed is grown in multilayer shelves. Natural light is let in through suitably glazed windows. Ayurvet's Hydroponics machine has successfully produced Wheat and Paddy nursery in the system. Bio conversion ratio was found to be 6-8 times. Specially prepared nutrient "NUTROSOL" and herbal solution "HERBOSOL" are used for the growth of plants and seed treatment respectively. Advantages includes - 1. Saving of water -- It takes just 2-3 ltrs of water to produce 1 Kg of green feed as compared with 80-9o litre/kg required in conventional system. 2. Marginal land usage -- On an average it requires less than 1/15th of the space needed by conventional agriculture to grow same amount of produce. 3. Reduction in growth time -- The growing time of hydroponics plants takes as little as 7 days from seed germination to a fully --grown plant at a height of 25.30 cm, ready for harvest. Also, the biomass conversion ratio is as high as 6-8 times under optimum conditions. 4. Reduced labour requirement -- This process of growing cattle feed requires minimal man-hour ratio per day. It is as little as 2 to 3 hours per day, needed to maintain & produce hydroponics green feed, as compared to the many hours of intense labour required for growing the same amount of feed as a pasture crop. 5. Constant feed supply- With our hydroponics machine, a consistent supply of green feed is guaranteed 365 days of the year. 6. Enhancement of nutritional value -- Hydroponic green feed is a highly effective particularly nutritious feed, which produces 3 times more protein as compared to conventional content. It has high energy content, Vitamin A & E content and very high moisture content. 7. Completely natural -- There are no pesticides or fungicides used for cultivation of crop and feed.
