I seize a leaf of peppermint from a mattress of mint leaves and style the extreme freshness. Subsequent, I have a look at thyme and odor the highly effective aroma. A bit away, purple basil with a stupendous, coppery glow beckon. I crush a lemon balm leaf, and take within the uplifting, gentle scent.
I’m at Parna Farms, Coimbatore’s first city hydroponic farm, situated proper within the coronary heart of the town at an industrial constructing campus. Unfold throughout 3,000 sq. ft, it grows 2,520 vegetation.
“Our recent lemon balm leaves impart a refined flavour and perfume, making it particularly good for custards, jam and jellies, truffles and tea,” says Akhila Vijayaraghavan, proprietor of the farm. “The purple basil is used for color in salads. Besides possibly amaranthus and palak (spinach), you may eat all of the greens we develop right here uncooked,” says Akhila pointing to forms of lettuce, basil, bok choy, and kale.
Asian water spinach (kang kong), crimson gongura, mustard leaves and methi (fenugreek) are a number of the new additions. “We additionally develop dill leaves, that are used as garnish for fish and meat dishes and pastas. Contemporary peppermint extracts are utilized in baking. We always attempt new crops based mostly on demand, after rounds of trial-and-error.”
A graduate of Molecular Biology from the College of Glasgow, Akhila ran her personal environmental consultancy for over 10 years earlier than turning an city farmer. “I labored with numerous firms, from prescribed drugs to FMCG, and learnt that offer of high quality end-product is a tough process. Agriculture has at all times been one in all my passions; I used to be considering meals crops. A herb can be utilized in cooking, to extract oil, extract vitamins in dry type, and possibly in different medication, perfumery… the probabilities are thrilling,” provides Akhila.
She researched hydroponic methodology and educated herself on farming earlier than diving into it. “Anybody can do it, it isn’t rocket science,” she says.
“Hydroponics combines each sustainability and know-how. In indoor hydroponic cultivation, the management on nutrient provide ensures extra high quality produce, for instance improved oil content material in herbs, in addition to higher crop yield. A hydroponic mint has extra methanol content material than a soil-grown one. The system additionally makes use of 80% much less water than typical agriculture. The water is upcycled for reuse.”
At Parna Farms, greens are grown utilizing the nutrient movie method (NFT), the place a skinny ‘movie’ of nutrient-rich water with macronutrients like nitrogen, potassium, phosphorous and calcium nitrate, and micronutrients like manganese and zinc nourish the roots of the vegetation.
The farm has germination space that makes use of coco peat to sprout vegetation, and a nursery the place web cups (small planters) are full of clay pebbles. There’s additionally the develop system, which entails metallic stands and PVC pipes connected to a lined nutrient tank that pumps water to the vegetation. “We incubate the online cups in a plastic tray for a few weeks. As soon as the plant grows roots, it’s transferred to the principle system with larger vitamins within the water. That is the place it’s absolutely grown and harvested,” explains Akhila.
Hydroponic agriculture, she says, has existed for over 3,000 years, with the Hanging Gardens of Babylon being one of many usually quoted examples of this system. “It is without doubt one of the extra accessible types of fashionable agriculture, tackling the twin issues of water shortage and lack of farmland. It reduces soil-borne pests and illnesses.”
Akhila says the target is to make sure that clients get recent, pesticide-free produce inside three hours of harvest. “Although a palak bunch from right here prices ₹130, they’re prepared to pay the premium to take pleasure in good well being,” says Akhila, including, “You’re what you eat. In hydroponics farming, day by day is a studying curve.”
