For a headline that explicitly excludes the 3rd essential component of growing (light, water, nutrients), the article mentions nothing about how these plants are getting nutrients. I assume they're supplementing liquid nutrients, as they're growing hydroponically in coco husks? If so, that makes the headline seem ridiculous... The coolest thing in the story for me is using salty air to repel pests. Though I wonder about the longevity of that solution. I've never seen a bullet-proof solution to pest control, and especially in self-contained environments, it's usually just a matter of time. Nevertheless, makes me wonder about a saltwater humidifier....
