Phase 7: Placement of the rows of bottles to construct the ceiling of the greenhouse.

After being presenting and placing the first rows of bottles of the coverage of the greenhouse, which already we explain in the previous paragraph how they were interlacing, they are adjusting and tightening with the interior rope in order that they acquire the suitable structure and some fit perfectly with others.

Later, with the rope every row of bottles is surrounding itself to join every row with the following one. This step we it will repeat every two bottles of the row and the rope will pass for the zone of union between bottles to reinforce the same one and to support the as compact as possible structure.

In the low part of the wings of the greenhouse, fixed to the arches, we place a wire following the whole line of the same one, in which later each of the rows will be sticking of bottles.

In the end of each one of the rows of bottles, we knot a chunk of wire that will be the one that is in use for fixing every row on the wire.

This way, each of the rows of bottles will be getting hooked up by the wire, obtaining this way a fixation that allows, besides his union, to support the sufficient tension in the structure of the cover of the greenhouse.

As we have commented, the climatological conditions have prevented us from being employed with continuity at the greenhouse. This way, we join some rows of bottles inside the Adults' Center; but we have verified that it is more suitable to prepare the rows in the moment previous to join them, for question of the expansion of the same ones with the changes of temperature, for what we prefer waiting for the moments that the climatology it allows to be working at the exterior, though it supposes delaying the construction.

As the rows are added, it is continued joining the same ones with the rope as it explained previously.

To help to spend the thread across the bottles, we have used a wire to facilitate his step. They are these small details that seem to be insignificant, but that at last make the labor much simpler and rapid.

The process has been the same during the whole placement of the cover and we have used some of the blue bottles gathered to give him a decorative touch to the greenhouse.

The work of placement of the coverage of the greenhouse we have been combining it with the preparation of the soil of the same one, which already we will detail in a following paragraph, but we leave here some images to show the good environment of participation and collaboration in the joint work realized by our pupils and for that always we have possessed the collaboration and support of the personal of the Penitentiary Center.
