I should have clarified re indoors: My comment was about setups like in the article, which are reliant on electric lights. One of the biggest limitations they have is electricity cost.

If you’re pumping water at any volume you’re using electricity (or fossil fuels).

You can build head with a windmill, but moving water (gpm) requires horsepower.

Also: LEDs are very efficient vs other types of lighting.

Sure, but how much energy compared to also running grow lights?

Yes, vertical farms will typically use LED lights.
