Lighting advances, climate control, nutrient factors, and innovations in high tech growing methods galore were showcased to the lucky 50 growers from around the world that signed up for the high tech greenhouse tour that took place during the 2015 Horticulture business days expo in Gorinchem Nl this past week.   For 2 days during the expo, these growers were hosted by various greenhouse operations growing orchids, lisanthus, greens, tomatoes and more.  It’s definitely worth a jump to this link at HortiDaily, a sponsor of the event, to see their photo report in detail.
