A method for a hydroponics farm comprising a light source, a container filled with a liquid medium, a plate support positioned above the container comprising a foam support, wherein the foam support supports a plant at a stem portion. The foam support may comprise a small foam fitted in a larger foam. The foam supports may allow ease of transfer of the plants among a plurality of plate supports. The method may comprise exposing the plants to a light source based on characteristics of the plants, such as based on a total plant density, a young plant density and a mature plant density. The method may also comprise periodically raising the level of the liquid medium, spreading a plant density, and oscillating the plant to promote growth.
