Comment Comment by ClumsyPilot Salads are economic to produce because they have no calories.Calories = Light (energy) + Fertiliser.Efficiency of an LED is like 40%, and Photosynthesis efficiency is like 2%.In other words calories are expensive and ineffieicent to produce through artificial lighting, no amount of 'startuping' will change that.Also nothing here is new, we've had greenhouses, artificial lighting, hydroponics, aquaponics, aeroponics and even vertical farms like 50 years. parent ClumsyPilot 5 years ago
Calories = Light (energy) + Fertiliser.
Efficiency of an LED is like 40%, and Photosynthesis efficiency is like 2%.
In other words calories are expensive and ineffieicent to produce through artificial lighting, no amount of 'startuping' will change that.
Also nothing here is new, we've had greenhouses, artificial lighting, hydroponics, aquaponics, aeroponics and even vertical farms like 50 years.
