Apparatus for growth and development of plants comprising: at least one plant development unit including: an enclosure for enclosing the root portions of plants including substantially humidity retaining side and bottom walls; a plant support member defining a generally flat top surface of said enclosure and including a layer of web material having apertures formed therein to receive plants above the root portions thereof without the provision of an intermediate element which surrounds a portion of the plant; said plant support member being characterized in that it exposes substantially all of the root portions of the plants to the atmosphere contained within said enclosure; nutrient spraying means for providing a nutrient mist enclosure, said nutrient comprising water and dissolved nitrogen and potassium fertilizers; nutrient collection and recirculation means defined in part by a bottom surface of said enclosure; control means for determining the timing of mist provision; environmental sensor means for determining conditions affecting plant transpiration including temperature and humidity inside said enclosure; means for heating said nutrient; and control means for determining the timing of mist provision, said control means being responsive to the outputs of said environmental sensor means indicating temperature and humidity for maintaining a desired temperature and humidity within said enclosure; wherein said spraying means comprises a centrally powered pneumatic system which draws liquid nutrient by venturi action; and wherein the nutrient collection and recirculation means of each plant development unit is isolated from each other plant development unit.
