Quote:
“They [vegetables] grow 22 hours a day, 365 days a year * * * although a couple of hours a day are necessary, says Gus van der Feltz of Philips, for the plant equivalent of sleep) * * * [so indoor farming with LED] could cut growing cycles by up to half compared with traditional farming.
“Water can be recycled continuously, and sensors can detect which nutrients are missing and provide them in small, accurate bursts.
Farms such as these are unlikely to be suitable for heavy crops like corn and potatoes—which grow pretty efficiently in vast fields. But if Green Sense Farms can prove its commercial worth, this form of farming could become widespread for leafy greens and other high-value crops. * * * Indoor farming is, happily, immune to both [insects and bad weather].
