Light pipes, like green houses, have an issue that the light source is blocked by the first plant it hits :-). The thing the article calls out that is different is that by using these thin GE grow LEDs they were able to have stacks and stacks of grow rows in a relatively small space.

That said, I would not be surprised to see some farmers in the central valley move to more green houses given their water rationing.
