"eSoil hydroponic electrically conductive cultivation substrate... barley seedlings grew up to 50% more in 15 days when roots stimulated electrically... seedlings process nitrogen more effectively, but it's not clear yet how the electrical stimulation impacts this process,... substrate made of cellulose, the most abundant biopolymer, mixed with a conductive polymer called PEDOT... very low energy consumption and no high voltage danger"
