After several years of intense experimental work, we conceived, built and tested the Plus4Zones ecological (unheated) greenhouse that enhances the local climate zone by 4 zones.
This allowed us to grow and harvest organic and delicious fruits that have never been successfully grown in the province of Quebec such as cherries, apricots, peaches, nectarines, figs, table grapes and others.
This P4Z ecological greenhouse can benefit people worldwide!
