I posted on the site BIOsCAMBIO, it autoproducer for their own consumption and for the gift-exchange of seeds and anything else useful to self, the "Practical Guide BIOsCAMBIO N°1: the bottle sprouter." The guide explains "step by step" a new and originalmethod for self-production plants, from seed, re-using emptyplastic bottles and disposable cups used.
Made of 43 slides, the "bottle method seedbed" is fully and freelydownloadable from the site as issued by the same authors in the PDA - Public Domain and Antiscadenza anticopyright antilicenza,"renounced all right."
Previewed at the Fair "Flowers at the Castle" Vicopisano (PI), 19-20 May 2012, the method is taken from an installation-performance of the Group "s "il ià jolie" the" series "autoproductions anticopyright" and was designed and developed by Rosella Federigi and myself (Domenico Vitiello), both also members of GASeS(Group Self Exchange and Solidarity) of Pisa, Italy.
