Phase 6: Assembly of the bottles to make the coverage of the greenhouse.

First, we perforate the low part of the bottle and the stopper in his respective centers to be able to introduce the rope that, finally, will happen for the whole row of bottles and will allow a better assembly of the same ones.

We are repeating the operation with the bottles and this way there is created every row that finally we will use as roofing in the greenhouse.

At first, we decide to place a stopper every 5 bottles (there are specific campaigns of collecting stoppers); but we verify, in early tests, that the structure was remaining slightly weak and it was difficult to manipulate without squashing the plastic for what finally we have put a stopper every two bottles what makes to us every row of bottles much more compact and this way it is not deformed, so easily, in his manipulation and placement in the roof of the greenhouse.

To complete each of the rows of bottles, in our case we have needed 40 bottles for row. Provided that, for every linear meter, we are necessary 12 rows of bottles, since the length of our greenhouse is 6 meters, finally the coverage of our greenhouse will to possess 2880 bottles.
