The invention is broadly in the agricultural field, more precisely in the field of industrial plant growth facilities. In particular, the invention concerns an industrial plant growing facility (100) for growing a variety of plants using predetermined growth conditions. Also, the invention concerns methods for growing plants in industrial plant growth facilities (100).

Means and methods are provided to produce abiotic stress tolerant plants with improved yield based on the specific identification of a DNA methylation signature in the plants out of a population of the plants. The methods involve identification and utilization of epigenetic features of a plant with high energy use efficiency

A method for raising leaf-and-stem vegetables and a light source device used in the method, which can make production cost of leaf-and-stem vegetables reduced and commercial value thereof enhanced by irradiating parts of leaf-and-stem vegetable with a light optimum therefor. The method for raising leaf-and-stem vegetables by irradiating the vegetables with light, includes a stem growth-inhibiting light source irradiating tops of the stems with light having a blue component light at high ratio, which inhibits the growth of stems, at least during an initial growth period when the stems and leaves become distinguishable from each other.

The present description relates to cryo-sprouts that have been germinated, grown and shipped in the same container. Seeds are placed on a membrane in the container with sufficient water. The container with the seeds is incubated at a pathogen antagonistic temperature during the growth phase. The pathogen antagonistic temperature is preferably between about 35? F. and about 45? F. The cryo-sprouts grown according to these methods have reduced numbers of pathogenic organisms, are greener and have an extended shelf-life.

The present invention provides a method of reducing nitrate content in a plant by supplementing Rhodopseudomonas palustris DSM 29314 with a hydroponic nutrient solution, wherein the plant can grow in the hydroponic nutrient solution. The bacteria can effectively reduce 50% to 88% of the nitrate content in the plant, and only requires half concentration of the hydroponic nutrient solution than usual to enhance the fresh and dry weight of the plant up to 17% to 44%. It can effectively reduce cost, increase income and provide safe crops.

A closed loop compost tea brewing system with a hydroponic reservoir and a compost tea brewing assembly configured to brew compost tea. The compost tea brewer assembly includes a tea brewing reservoir. The system includes has a closed loop arrangement fluidly connecting the tea brewing reservoir and the hydroponic reservoir. The closed loop arrangement is configured to provide continuous fluid flow from the tea brewing reservoir to the hydroponic reservoir, which is recirculated back from the hydroponic reservoir to the tea brewing reservoir.

Disclosed are methods of producing nutrient solutions having unique isotopic fingerprints; methods of producing traceable plants; and methods of identifying the source of a traceable plant that does not rely on expensive artificially separated isotopes. Plants grown with these nutrient solutions will have unique isotopic fingerprints that will be difficult or impossible to counterfeit.
