Chennai-based biotechnology graduate Rahul Dhoka’s rooftop looks like a maze. Only, it’s a maze of over 6,000 organically grown leafy vegetables and herbs such as carrom, kale, lettuce, and spinach.
These vegetables, grown in planters made of PVC pipes that have taken over his 90 square feet rooftop, are grown using hydroponics technique—a method of growing plants in nutrient rich water instead of soil. Non-commercial hydroponics farming does not require large spaces and can be grown on rooftops like Dhoka’s or even in a smaller set-up such as a doorstep. They can also be designed as vertical farms to optimize the land area.
Nanoco Group PLC (LON:NANO) leads the world in the research, development and large-scale manufacture of heavy metal-free nanomaterials for use in displays, lighting, vertical farming, solar energy and bio-imaging.
