This invention relates generally to plant growing systems and methods, and more particularly, to container-based indoor farming systems and methods.
Traditional agricultural methods are labor and land intensive and dependent on local climate and weather conditions. Various indoor farming technologies have been developed to address these issues and to produce higher yields in controlled environments.
Unfortunately, current indoor farming systems come with their own limitations. For example, existing aeroponic systems are labor intensive and are not easily automated. In addition, the dense growing environments created by some indoor farming systems can create a stagnant micro-climate under the plant canopy that is susceptible to mold and mildew. Technologies to support aeroponic systems can also be complex, expensive, and difficult to maintain and clean.
It should be appreciated that there is a need for a scalable, automated indoor farming system having component parts that are easily maintained and cleaned. The improved indoor farming system should provide a healthier and more efficient growing environment, and generate a higher crop yield at a lower energy cost. The present invention fulfills these needs and provides further related advantages.

In use, the plant growing system 200 is capable of refreshing the microclimate under a plant canopy 20. When plants 10 are grown in tight proximity to each other an unhealthy microclimate may develop under the plant canopy 20. For example, the tightly packed leaves may shield the area under the plant canopy 20 from moving air and the concentration of CO2 beneath the canopy may fall below an optimal range. At the same time, moisture from the plant 10 and the horticultural plug or soil may accumulate in the stagnant air to create a damp microclimate that is susceptible to the development of mold or mildew. The porous air hose 255 can pump fresh air 25 under the plant canopy 20 to mitigate moisture development, maintain or restore optimal CO2 levels, or both. Carbon dioxide enrichment under the plant canopy will increase crop yield and reduce lighting requirements.
