The exterior of the greenhouses were unimpressive . . . grey, cheap plastic.
It was a different story when they opened the doors though; it was beautiful, colorful and alive.
We visited 4 different nurseries, two orchids, one rose and one gerber daisy. All of them are completely computer controlled. If it gets too hot, the roof opens, too cold and the heaters come on, sensors control the water and any excess that drips out get recycled. It's pretty amazing.
And look at the flowers!
