With temperature, light and humidity controlled across 12 growing 'rooms,' pollination of plants has also been engineered to be more efficient than bees.

I need more details on this "more efficient than bees" claim. I grow a couple of hydroponic strawberry plants for fun, and every strawberry is a result of my swirling a toothbrush around a flower. I am having a hard time imagining scaling that up without bees.
