Thanks to technology, vegetables can now be grown in outer space and deserts, even subterranean tunnels, and soon, the most hostile environment of all: supermarkets. During your rush hour shop, instead of fighting over ready meals you may find yourself in pick-your-own strawberry bliss on aisle 12, free of plastic packaging and air miles.

Energy-efficient LED grow lights, robots and internet-connected vertical farms are some of the technical breakthroughs that are revolutionising edible gardening, notably in places with no outside space at all. And with our global population closing in on eight billion - a majority in garden-less urban apartments - this futuristic tech promises to remove pressure from our natural world (and our own to-do lists) in the nick of time.

Supermarket farming aisles

German company InFarm has more than 100 vertical microfarms already in shops across Germany, Switzerland and France with plans to bring them to the UK. Shelving units with grow lights and hydroponic trays of nutrient-rich water, they resemble shop refrigerators growing live salads, veg, herbs and fruit. Staff simply slide trays in to grow and out once customers have picked everything.

One Bristol-based start-up also hopes to bring vertical farms to high streets using aeroponics that spray roots in a nutrient mist. India Langley, of LettUs Grow, says aeroponics give plants “better access to oxygen and carbon dioxide which results in them growing much faster: we have shown a 70 per cent increase in growth rate compared with hydroponics.”

Langley is keen to highlight benefits including lack of pesticides, “by reducing food miles, we can help slash food waste and reduce the carbon footprint of fresh produce, around 50 per cent of bagged salad we buy in the UK ends up in the bin.”
