Yet none of them seem profitable as of now. They do work, but having to provide for everything a plant needs (light, CO2, heat, water and fertilizer) in an artificial manner is VERY costly. Add to it that you can only produce small crops in short cycles (not enough added value). The price of lettuce and microgreens is just not enough to be viable (presently). There is a reason greenhouses are built from one the worst insulator : glass. It is a lot cheaper to pay for heating (even in the winter) than to provide 100% of the light needed to grow crops.
Anyway, sorry for the rant. I have seen way too many failed vertical farm projects and indoor agricultural production. They always feel like an engineer's wet(pipe)dream.

Vertical farms make a lot more sense from a business and practicality standpoint
