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.
