While hydroponic farms do allow a lot of crop plants to be grown in a relatively small space, they would certainly be a better alternative to traditional farms if those plants grew faster. That could soon be the case, thanks to the development of electrically conductive “eSoil.”

Although hydroponic farms don’t use actual soil, they do utilize a cultivation substrate for the plants’ roots to grow into. Mineral wool is frequently used for this purpose, although its production requires a great deal of energy, plus it doesn’t biodegrade once discarded.

Given the fact that electrical stimulation of the roots had already been shown to boost plant growth, scientists from Sweden’s Linköping University set out to develop an alternative substrate that was both eco-friendly and highly electrically conductive.
