Stackable sheet formed container, and use, for plant growth, and shipment

A vegetation growth apparatus, comprising

• a) substantially planar, insulative plastic sheeting formed into a stackable box shape container having only four side walls,
• b) said container having an interior sized to contain receptacles containing initial growth vegetation,
• c) certain of said walls having slits sized to permit roots of certain of said vegetation to be pushed through the slits, and into potting material introduced into said container interior, and enabling vegetation growth alongside the container whereby the container remains stackable,
• d) there being divider sheeting received in the container interior between two container interior sections, the divider sheeting forming an irrigation flow passage between said two sections via upper outlets in the divider sheeting, and a sheeting tray underlying said side walls, divider sheeting and interiors of said sections, there being a lid everywhere spaced from said tray, certain of said side wall slits exposed to the container exterior, between the tray and lid,
• e) the container divider sheeting and the tray consist of the same plastic material forming insulative, elongated cells,
• f) and wherein the tray has side and end walls and a a tray bottom wall, and the entire divider sheeting, tray, and tray side and end walls initially all having everywhere co-planar, parallel, sheet configuration, and subsequently having folding along pre-formed fold lines into ultimate container, divider and tray configurations, wherein all of the tray and container side and end walls are folded upwardly to extend vertically away from said tray bottom wall into a rectangular tray configuration underlying said side and end walls,
• g) said side walls containing elongated parallel cells, the side walls forming hinges for wall flaps adjacent said slits, which are parallel to said cells.
