A 2020 U.S. survey found that typical indoor agriculture crops, per pound of crop yield, consumed between US$0.47 (for leafy greens) and US$1.38 (for microgreens) in inputs (especially seed, growing media, and nutrients) -- though tomatoes were reported at US$0.06 inputs per pound. Labor costs for container farms were reported at US$2.35 per pound.
The average crop-time for fast-growing microgreens, such as many brassicas, is 10–14 days from seeding to harvest. [1] [3] [4] Slower growing microgreens, such as beets, chard, and many herbs, may take 16–25 days to reach harvestable size. Both baby greens and microgreens lack any legal definition.
Moreover, aeroponics provides an enclosed and controlled environment, making it an ideal system for growing pathogen-free seed stocks. The enclosed growth chamber, combined with the isolation of plants from each other, serves to prevent initial contamination from external pathogens and limits the spread of any existing pathogens among plants.
Because of these irreconcilable conflicts, Gericke left his academic position in 1937 in a climate that was politically unfavorable and continued his research independently in his greenhouse. In 1940, Gericke, whose work is considered to be the basis for all forms of hydroponic growing, published the book, Complete Guide to Soilless Gardening ...

Plants placed into nutrient-rich water channels in an NFT system A home-built NFT hydroponic system. Nutrient film technique (NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known as channels.
Intensive agriculture, also known as intensive farming (as opposed to extensive farming), conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area.
The plant microbiome, also known as the phytomicrobiome, plays roles in plant health and productivity and has received significant attention in recent years. [1] [2] The microbiome has been defined as "a characteristic microbial community occupying a reasonably well-defined habitat which has distinct physio-chemical properties.
