title: The Minitron system for growth of small plants under controlled environment conditions.
abstract: The design and operation of a system is described in which small plants can be grown under controlled environment conditions.  Important features of this "Minitron" system include precise control of temperature and CO2 concentration in a flowing atmosphere.  Plants can be grown either hydroponically or in solid root support medium.  For either culture method, nutrient solution or water is added from an external reservoir, altering neither atmospheric composition nor temperature equilibrium within a closed Minitron chamber.
