A new 'electronic soil' speeds up plant growth by 50%

I came across this research from Linköping University and thought the approach was fascinating.

They've developed a low-power, soil-like substrate made from cellulose and a conductive polymer. By electrically stimulating the roots of barley seedlings grown in it, they saw a 50% increase in growth in just 15 days.

The interesting part is that it's not just feeding the plant more energy; the stimulation seems to make the plant process nitrogen more efficiently. It's a hydroponic system, so it's not for open-field farming yet, but it's a wild idea for vertical farms or space habitats where maximizing growth speed in a small area is the main goal. Seems like a novel way to approach agritech.
