Exemplary sprouters may provide automatic water level adjustment for soaking seeds and growing sprouts from those seeds in trays formed from a hydrophobic material and with holes in the bottom surface of the tray sized such that the surface tension of pure water and the hydrophobic properties of the tray material resists passage of the pure water through the holes. The automatically adjusting may be facilitated by germinating seeds soaking in water changing the surface tension of the soaking water and reducing the resistance to passage through the holes.
