In space-constrained Japan, GE helped launched an indoor farm that grows lettuce 2.5 times faster than conventional outdoor agriculture, while cutting waste to just 10 percent (compared to upward of 50 percent outdoors) and water consumption to only 1 percent of conventional outdoor farming. The trick? LED lighting.
Sorry, I don't believe it. Senator McCain told me that only Mexicans can harvest lettuce. < /sarc>
I hated CFLs from the beginning, but in general love my LEDs. I have 3 CFLs left. One I barely use, one is the 150-watt one I want to replace, and one is an outside light that I will soon replace. Other than that all my new bulbs are either LEDs or a few halogens.
I bought some Halo LED conversions for recessed light cans the other day for $25 at Home Depot. They’re nowhere near 150 watts though.
He was wrong, but don't think that Japanese workers are picking this lettuce. Japanese LED lettuce is actually picked by robots. The entire facility is automated.
