Prakhar Agarwal and Tanay Tiwari’s IIT Kanpur incubated startup, Macrogardens makes aeroponic towers that allow you to develop 30 occasions extra greens in small balconies.
Delhi’s Abhishek Gupta has arrange a kitchen backyard to save lots of his household from consuming pesticide-laden greens from the market. Just lately, he included a novel aeroponic tower in his kitchen backyard that grows 32 vegetation in an space that beforehand allowed the expansion of solely two vegetation.
“This tower occupies as a lot area as an individual takes whereas standing. And on this small area, I’m rising a number of vegetation like ladyfingers and lettuce. I harvest lettuce for my salad each single day! Subsequent, I’m planning to develop bell peppers,” Abhishek tells The Higher India.
“This vertical tower can also be low on upkeep. I simply have so as to add vitamins as soon as in 7 to 10 days. I’m so proud of this product that I’m planning to buy two extra such towers,” provides the software program engineer.
Aeroponics is a subset of the soil-less hydroponic technique. On this technique, the roots of the vegetation are suspended within the air and irrigated with a nutrient-dense mist. Taking this idea into consideration, Lucknow-based Prakhar Agarwal and Tanay Tiwari developed a novel vertical tower to develop veggies in small areas, appropriate for small condominium balconies in massive cities.
In dialog with The Higher India, Prakhar explains how the aeroponic tower can revolutionise farming in cities.
Meant for balconies
Prakhar, a pc science graduate by training, was at all times keen about rising his personal greens. Apart from decorative vegetation, he wished to develop veggies on his balcony however with out choosing a tedious soil-based system.
“That is once I got here throughout the soilless hydroponic and aeroponic programs. Whereas hydroponics requires a horizontal system utilizing PVC pipes that find yourself taking on quite a lot of area, I wished a small setup appropriate for a balcony,” says the 25-year-old.
When the varsity buddies Prakhar and Tanay have been researching extra on the aeroponic system, an incident compelled them to gas the method. “As soon as, I drank sugarcane juice from a avenue vendor and fell sick. It was so dangerous that I used to be sick for almost 4 months. I knew it was excessive time that we develop our personal meals at dwelling,” he says.
In 2020, Prakhar began engaged on designing an aeroponic tower together with Tanay, and collectively, they launched ‘Macrogardens’ – an IIT Kanpur incubated startup.
“As we wished to optimise area, we wished to develop one thing vertical in contrast to a horizontal PVC pipe hydroponic setup,” he says including that lastly, after engaged on at the very least 20 designs, the buddies got here up with an aeroponic tower that was appropriate for balconies in small residences.
Helps develop 30 occasions extra meals
Utilizing food-grade plastic, Prakhar and Tanay developed an aeroponic tower with 32 modules. “Residences, particularly in cities like Bangalore and Delhi, should not have sufficient area for gardening. It lets you preserve only a few vegetation. However with aeroponic towers, anybody can develop 30 occasions extra produce at a 20 p.c quicker fee in comparison with a soil-based setup,” he says.
Giving an instance, the engineer explains, “One would require an area of 4 sq. toes to develop two cauliflowers. However one can develop 64 cauliflowers in the identical space utilizing aeroponic towers. We now have given 32 pods in a single tower that enables the expansion of two saplings in every pod.”
“Additionally, normally individuals fear about their vegetation withering away once they have to go away for trip or on a piece journey. They’re depending on their neighbours to water their vegetation. However our system resolves that situation as nicely,” he provides.
Prakhar informs that their aeroponic tower robotically sprays water on vegetation utilizing a motor and a water tank that may retailer 65 litres of water. “With this, vegetation can survive for 20 to 30 days with none upkeep. And the facility prices solely Rs 35 to Rs 40 for a month,” he provides.
Moreover, he claims that the aeroponic tower saves as much as 95 p.c water in comparison with a soil-based system the place water is misplaced to transpiration, evaporation, and a big floor space.
Apparently, the aeroponic system — meant for city residents and small-landholding farmers — permits one to develop quite a lot of greens from inexperienced leafy spinach and lettuce to tomatoes, woman fingers, cucumbers, and even tubers like radish and potatoes.
Making cultivating meals simple
The aeroponic tower is priced at Rs 6,500. Together with it, Prakhar additionally provides seeds, cocopeat as media, and 17 sorts of nutrient combine comprising nitrogen, phosphorus, potassium, iron, and hint components like manganese, molybdenum, and zinc.
“The one factor that customers want to remember is including the nutrient to the water provide each 12 to fifteen days in summer time and each 25 days in winter. With our system, you additionally don’t must preserve checking TDS and pH ranges within the water. Our major goal is to indicate individuals the convenience of rising meals at dwelling,” he says.
With this, Prakhar goals to see a behavioural change amongst city residents. “Meals cooked utilizing freshly harvested produce is healthier in its texture and flavour. At any time when I harvest kakdi (cucumber), my mom finds it juicy and mushy. However typically, by the point greens from outdoors attain our plate, they lose their freshness and vitamins.”
“Numerous individuals wish to develop their meals, however with a rising inhabitants and reducing farmland, aeroponics appears to be the way forward for farming. I want for each metropolis dweller to develop their very own pesticide-free meals with this technique,” he provides.
