Greenhouses could take root at Japan's eateries
The Chef's Farm, as it's called, could produce up to 60 heads of lettuce a day. If you do your math, that's about 20,000 heads a year.
Fancy your lettuce fresh off a farm? Dentsu Facility Management is planting the idea of an on-site greenhouse for restaurants that's capable of producing up to 60 heads of lettuce a day. If you do your math, that's about 20,000 heads a year.
The "Chef's Farm" measures about 13 feet wide by 5 feet deep by 7.5 feet tall and comes with five planting beds with sponges to nurture individual seeds; 12 40-watt fluorescent lamps to imitate sunlight; an air shower for moisture; plus a whizbang of gadgetry to monitor lighting strength, water levels, and bed temperatures. Five types of vegetables can be cultivated, which makes for a veritable salad on tap. But whether this idea takes root remains to be seen as there's a hefty 8.3 million yen ($90,552) investment that will take about five years to recoup.
