Abstract: A planter may include a housing configured to house one or more growth units, which are individual positions in the planter for growing an individual plant. The planter may include one or more liquid supply lines embedded in an upper portion of the housing, and a drain line embedded in a lower portion of the housing. A drain that is configured to remove liquid from the planter and supply the removed liquid to a pump via the drain line may also be provided. An upper surface of the housing of the planter may include, for each of the one or more growth units, a through hole that passes through the upper surface of the planter housing into the inner chamber of the growth unit.
