A growing trend in urban Japan is indoor farming. As farmland is scarce, a wide variety of herbs and greens can be cultivated in climate-controlled environments under LED lighting at home for energy efficient food production.
Two Japanese farms (Indoor Urban Farming and the Innovatus Fuji Farm in Shizuoka Prefecture) cover almost 20,000 square feet. Farmers here have spent the last year growing five different kinds of lettuce with 12,000 heads of lettuce growing under horticultural LED lighting technology.
Produce mainly includes frilled lettuce, green leaf, and romaine. Their vertical farm set-up is efficient and saves on land, energy and water. Here, produce can be picked, packaged, and sent to store shelves in less than two hours…and it’s not just here. At Delicious Cook’s urban farm (Narashino City, Chiba Prefecture) a diverse selection of edible herbs are also being grown under LED lighting, experimenting successfully with less common herb varieties such as chrysanthemums and coriander. The farm recently finished a 10-month trial where unusual herbs were grown under Philips GreenPower LED system. The resulting crops will be used in the company’s processed food products.
By using Philips horticultural lighting LED systems, farmers are able to set precise combinations of light, temperature, and humidity for the optimal production of each produce type. In using this approach, crop yields are amplified, and quality and flavor remain consistent. Superb!
