Saw that video a while back and the funny thing is, since then, Ive figured out that if you really want to maximize production on a large scale like that, the individual 'canopied' plants is not the ideal way to grow dragon fruit. On very large scale, they should be grown like grapes are, long continuous rows on trellis like supports, with the rows running North to South, not East to West or some other random direction. These plants need direct sunlight to produce fruit and the canopy shape means that for about 8 months of the year, one side is in perpetual shade and the other is in sun all year. As the summer approaches, and the sun gets higher, it hits more of the plant, but as winter gets near, and the sun lowers, a good portion of the plant loses any direct sun, which lowers fruit production in those areas. If you watch the video, as the camera pans across the orchard, almost every plant has fruit or flowers on the same parts of the plants.
Now, for us home growers, this is mostly a moot point, unless you have a big yard and you plan on dedicating a lot of space to this fruit, but for larger scale growers, its something to consider.
