Australia has a number of large veggie producers that use glasshouses for growing and have been around and successful for many years. Look up Flavorite and Perfection Fresh for two examples.
Perfection seem to be using a lot of foil tunnels: https://www.perfection.com.au/our-farms/perfection-berries-r... Which makes sense, because they're cheap and easy to construct. But for some reason "indoor farming" startups don't seem very interested in taking the simplest solution that could possibly qualify as "indoors" and scaling it up.
