Growing marijuana for recreational and, above all, medicinal use is an interesting business in the US and Canada. The number of grow rooms is increasing every year and with it the potential for our diffusers. They are ideal for generating required conditions (uniform temperature and sufficient airflow for leaves moving) so that these controversial plants can achieve maximum growth. We have delivered more than 3 km of fabric diffusers in two phases and they have been installed in 24 rooms of the Canadian company WeedMD. Looking at the photos, it seems the plants are doing well.
