Many health-conscious people around the world are beginning to grow their own food, says Market research group Garden Media .

According to a 2017 Garden Trends Report, clean, healthy living is driving changes in the garden industry today, with 37 percent of millennials and 28 percent of baby boomers growing herbs indoors.

Garden Media predicts that despite living in sampler spaces in urban environments, more people will be growing plants indoors, as they crave organic local food.

In its 2016 Life at Home survey, furniture maker Ikea reported that six in 10 people worldwide now grow vegetables and flowers indoors, with the balcony as the favorite green spot.

"Gardening in this general sense is most widely rooted in Shanghai, where three quarters of the population grow something at home," the Ikea report said. "Decorative plants and flowers are the norm in Shanghai and Mumbai. New Yorkers are just as likely to grow vegetables as flowers."

Growing a happy home

Based on Ikea's study, metropolitans have many reasons for growing, but the most stated ones are: for fun, to decorate their homes, and to have fresh produce available when they cook.

City growers also claim that they enjoy their weekdays more than the others, from simply caring for something, seeing what they've planted thrive or eating something they've grown.

Technology is making indoor gardening easier

Seeing a budding and potentially lush market, Ikea released a new product called the Growroom, a nine-foot tall wooden spherical greenhouse made of shelves to grow various plants. This is primarily for herbs, vegetables and fruits, which can be grown indoors. The unique furniture is a do-it-yourself stuff.

Ikea designers teamed up with architects Sine Lindholm and Mads-Ulrik Husum to create the Growroom, as they saw a demand in locally grown food.

"Standing tall as a spherical garden, it empowers people to grow their own food much more locally in a beautiful and sustainable way," the designers wrote on Medium.

"Technology is making indoor gardening easier," noted Garden Media.

The market research group predicts that practice of "growing under lights" will increase by 6.3 percent yearly through 2021, faster than the projected US GDP growth rate of 2.2 percent over the same period, as IBISWorld forecast. "Gardening indoors gives anyone living anywhere access to grow 365 days of fresh, healthy food," Garden Media stated.
