For YouTuber Kazuki Nakata, the recent price trends have proved to be a boon. Having started indoor farming at home as a hobby during the pandemic, the 37-year-old now has nearly 90,000 subscribers eager to learn how to stretch out store-bought vegetables and grow new ones in containers of water, without soil. "I've seen 4,500 new followers in the past two weeks," he told Reuters at his home in Kawasaki, outside Tokyo, this week. Nakata quit his job at an electronics retailer in 2023 to focus on the 47 types of vegetables he currently grows all over his house. Everything from shiso leaves, onions and daikon radish thrive in empty plastic bottles, beer cans and even the basket of his bicycle. Growing vegetables at home isn't without its challenges. Nakata's family has had to sleep without air conditioning on sweltering summer nights, and his wife complains that she can't breast-feed her newborn in the living room because the curtains need to be open to ensure the leafy greens get their sunlight. Still, with vegetable prices so high, Nakata says the sacrifices have paid off. He recently succeeded in cultivating a robust patch of cabbage leaves in a kitchen bowl using the inedible core and liquid fertilizers - the subject of his next video on YouTube.
