TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The first six pockets: admeasure 24 inches x 8 inches; and are heat-sealed on the green exterior side of the side panel (100-2) in a position, perpendicular to longitudinal axis of the side panel (100-2) of the tetra vermi bed. The second six pockets: admeasure 24 inches x 8 inches; and are heat-sealed on the green exterior side of the side panel (100-3) in a position, perpendicular to longitudinal axis of the side panel (100-3) of the tetra vermi bed. Each of the thirteenth and fourteenth pocket: admeasures 24 inches x 8 inches; and is heat-sealed on the green exterior surface and near the other lateral side of the main panel (100-1), in position parallel to the longitudinal axis of the main panel (100-1). The first three windows are centrally cut open from the side panel (100-2) in 8 inches x 4.5 inches openings with round corners which are heat-sealed with HDPE nets. The last two windows are centrally cut open from the side panel (100-3) in 8 inches x 4.5 inch openings with round corners which are heat-sealed with HDPE nets. The fourteen pockets are heat-sealed on two sides of the pockets over a 6 inch clearance along the entire length of the pockets. The side panels are rope-folded by 2 inches at one longitudinal end that is farthest from the inverted, U-shaped mouth of the first twelve pockets. The main panel is rope-folded by 2 inches at both lateral ends, which are farthest to the inverted, U-shaped mouth of the last two pockets. Each side panel at unroped longitudinal side is heat sealed with one longitudinal side of the main panel. Two lateral sides of each side panel are each heat-sealed with extended longitudinal sides of the main panel to form vertical comer joints (100-4 to 100-7) that are folded sideways by 2 inches and sealed over folds for additional strength. The window (70-1, 70-2, 70-3, 70-4, 70-5, 70-6) each is 4.5 inches away from the adjoining, inverted U-shaped pocket ((80-1, 80-2), (80-3, 80-4), (80-5, 80-6), (80-7, 80-8), (80-9, 80-10), (80-11, 80-12)) respectively. The inverted U-shaped pocket (80-1, 80-6, 80-7, 80-12) each is 5 inches away from the vertical comer joint (100-4, 100-5, 100-6, 100-7) respectively. Each of the first twelve inverted U-shaped pocket at U-shaped one end is heat-sealed-along with the side panels to the main panel and at the closed other end is anchored over the roped top side of the side panels by cutting out a U-shaped portion off the closed other end and heat sealing it with the side panels. Each of the last two inverted U-shaped pocket at closed other end is anchored over the roped top side of the main panel by cutting out a U-shaped portion off the closed other end and heat sealing it with the main panel. The vermicomposting bed is installed on well laid ground having a gradient of 6 inches over 12 feet by: marking correctly fourteen locations for grouting the fourteen wooden poles on an area selected for installation, where the selected area of the well-laid ground admeasures 15 feet x 6 feet; digging the marked positions into fourteen holes, where each of the hole admeasures 3 inches in diameter x 18 inches deep; grouting each of the wooden pole in each of the dug hole so that each of the pole rises above the well-laid ground to a height of 21 inches; inserting the fourteen pockets onto the respective fourteen wooden poles of the tetra vermi bed simultaneously and sliding down gradually the tetra vermi-bed over the wood wooden poles till the tetra vermi bed touches the well laid ground all along its periphery; and fitting the drain pipe under the drain, so that the tetra vermi bed sits atop the semi-circularly cut-open portion of the drain pipe and placing the other end of the drain pipe above a container, placed in a dug-out pit for collecting vermi wash liquid. In the vermi composting bed, four eyelets are provided at top four comer points of the tetra vermi bed for roping the top edges of the side panels and of the main panel, where the eyelets are covered with folding flaps to protect the roping from damage by the edges of the eyelets.
