Environmental chamber for plant growth analysis

A stand-alone growth cabinet for outdoor use in conducting plant experiments, comprising:

• a frameless upright container comprised of transparent interconnected panels forming a day-lit chamber shell, said chamber shell comprising a pair of side panels, a back panel, a front panel, a roof, and an integral floor panel;
• wherein said interconnected panels are chemically bonded along their periphery to provide a substantially air-tight and frameless chamber shell, adapted to maximize entry of daylight into said growth cabinet;
• a horizontal surface within said chamber shell forming a horizontal plant supporting floor, said horizontal floor having perforations or slots there through on its entire surface;
• a transport vertical surface within said chamber shell rising from said horizontal floor to define an air return plenum adjacent the back panel of said chamber shell, said transparent vertical surface adapted to direct air from said perforated or slotted horizontal floor over the top of said vertical surface and down said air return plenum, said vertical surface and horizontal floor together defining a growth chamber with the chamber shell, said growth chamber being adjacent to the front panel of the chamber shell;
• said transparent panels and said transparent vertical surface being formed of the same plastic material;
• a base having sufficient height to insulate said growth chamber from ground temperature and defeating wind loads;
• means for opening and sealingly closing said growth chamber, said means comprising a door at the front of said chamber shell;
• means for equalized distribution of air forced into said growth chamber associated with said chamber shell;
• and,
• means for control of temperature and humidity, and optionally for monitoring and controlling of carbon dioxide within said growth chamber associated with said chamber shell.
